Introduction

Teletype is a dynamic, musical event triggering platform.

What's new?

Version 2.1

Teletype version 2.1 introduces new operators that mature the syntax and capability of the Teletype, as well as several bug fixes and enhancement features.

Major new features

Tracker Data Entry Improvements

Data entry in the tracker screen is now buffered, requiring an ENTER keystroke to commit changes, or SHIFT-ENTER to insert the value. All other navigation keystrokes will abandon data entry. The increment / decrement keystrokes (] and [), as well as the negate keystroke (-) function immediately if not in data entry mode, but modify the currently buffered value in edit mode (again, requiring a commit).

Turtle Operator

The Turtle operator allows 2-dimensional access to the patterns as portrayed out in Tracker mode. It uses new operators with the @ prefix. You can @MOVE X Y the turtle relative to its current position, or set its direction in degrees with @DIR and its speed with @SPEED and then execute a @STEP.

To access the value that the turtle operator points to, use @, which can also set the value with an argument.

The turtle can be constrained on the tracker grid by setting its fence with @FX1, @FY1, @FX2, and @FY2, or by using the shortcut operator @F x1 y1 x2 y2. When the turtle reaches the fence, its behaviour is governed by its fence mode, where the turtle can simply stop (@BUMP), wrap around to the other edge (@WRAP), or bounce off the fence and change direction (@BOUNCE). Each of these can be set to 1 to enable that mode.

Setting @SCRIPT N will cause script N to execute whenever the turtle crosses the boundary to another cell. This is different from simply calling @STEP; @SCRIPT N because the turtle is not guaranteed to change cells on every step if it is moving slowly enough.

Finally, the turtle can be displayed on the tracker screen with @SHOW 1, where it will indicate the current cell by pointing to it from the right side with the < symbol.

New Mods: EVERY, SKIP, and OTHER, plus SYNC

These mods allow rhythmic division of control flow. EVERY X: executes the post-command once per X at the Xth time the script is called. SKIP X: executes it every time but the Xth. OTHER: will execute when the previous EVERY/SKIP command did not.

Finally, SYNC X will set each EVERY and SKIP counter to X without modifying its divisor value. Using a negative number will set it to that number of steps before the step. Using SYNC -1 will cause each EVERY to execute on its next call, and each SKIP will not execute.

Script Line "Commenting"

Individual lines in scripts can now be disabled from execution by highlighting the line and pressing ALT-/. Disabled lines will appear dim. This status will persist through save/load from flash, but will not carry over to scenes saved to USB drive.

New Operators

W [condition]: is a new mod that operates as a while loop. The BREAK operator stops executing the current script BPM [bpm] returns the number of milliseconds per beat in a given BPM, great for setting M. LAST [script] returns the number of milliseconds since script was last called.

New Operator Behaviour

SCRIPT with no argument now returns the current script number. I is now local to its corresponding L statement. IF/ELSE is now local to its script.

New keybindings

CTRL-1 through CTRL-8 toggle the mute status for scripts 1 to 8 respectively. CTRL-9 toggles the METRO script. SHIFT-ENTER now inserts a line in Scene Write mode.

Bug fixes

Temporal recursion now possible by fixing delay allocation issue, e.g.: DEL 250: SCRIPT SCRIPT KILL now clears TR outputs and stops METRO. SCENE will no longer execute from the INIT script on initial scene load. AVG and Q.AVG now round up from offsets of 0.5 and greater.

Breaking Changes

As I is now local to L loops, it is no longer usable across scripts or as a general-purpose variable. As IF/ELSE is now local to a script, scenes that relied on IF in one script and ELSE in another will be functionally broken.

Version 2.0

Teletype version 2.0 represents a large rewrite of the Teletype code base. There are many new language additions, some small breaking changes and a lot of under the hood enhancements.

Major new features

Sub commands

Several commands on one line, separated by semicolons.

e.g. CV 1 N 60; TR.PULSE 1

See the section on "Sub commands" for more information.

Aliases

For example, use TR.P 1 instead of TR.PULSE 1, and use + 1 1, instead of ADD 1 1.

See the section on "Aliases" for more information.

PN versions of every P OP

There are now PN versions of every P OP. For example, instead of:

P.I 0
P.START 0
P.I 1
P.START 10

You can use:

PN.START 0 0
PN.START 1 10

TELEXi and TELEXo OPs

Lots of OPs have been added for interacting with the wonderful TELEXi input expander and TELEXo output expander. See their respective sections in the documentation for more information.

New keybindings

The function keys can now directly trigger a script.

The <tab> key is now used to cycle between live, edit and pattern modes, and there are now easy access keys to directly jump to a mode.

Many new text editing keyboard shortcuts have been added.

See the "Modes" documentation for a listing of all the keybindings.

USB memory stick support

You can now save you scenes to USB memory stick at any time, and not just at boot up. Just insert a USB memory stick to start the save and load process. Your edit scene should not be effected.

It should also be significantly more reliable with a wider ranger of memory sticks.

WARNING: Please backup the contents of your USB stick before inserting it. Particularly with a freshly flashed Teletype as you will end up overwriting all the saved scenes with blank ones.

Other additions

Breaking changes

WARNING: If you restore your scripts from a USB memory stick, please manually fix any changes first. Alternatively, incorrect commands (due to the above changes) will be skipped when imported, please re-add them.

Known issues

Visual glitches

The cause of these is well understood, and they are essentially harmless. Changing modes with the <tab> key will force the screen to redraw. A fix is coming in version 2.1.

Quickstart

Panel

Panel Overlay
Panel Overlay

The keyboard is attached to the front panel, for typing commands. The commands can be executed immediately in LIVE mode or assigned to one of the eight trigger inputs in EDIT mode. The knob and in jack can be used to set and replace values.

LIVE mode

Teletype starts up in LIVE mode. You'll see a friendly > prompt, where commands are entered. The command:

TR.TOG A

will toggle trigger A after pressing enter. Consider:

CV 1 V 5
CV 2 N 7
CV 1 0

Here the first command sets CV 1 to 5 volts. The second command sets CV 2 to note 7 (which is 7 semitones up). The last command sets CV 1 back to 0.

Data flows from right to left, so it becomes possible to do this:

CV 1 N RAND 12

Here a random note between 0 and 12 is set to CV 1.

We can change the behavior of a command with a PRE such as DEL:

DEL 500 : TR.TOG A

TR.TOG A will be delayed by 500ms upon execution.

A helpful display line appears above the command line in dim font. Here any entered commands will return their numerical value if they have one.

SCRIPTS, or several lines of commands, can be assigned to trigger inputs. This is when things get musically interesting. To edit each script, we shift into EDIT mode.

LIVE mode icons

Four small icons are displayed in LIVE mode to give some important feedback about the state of Teletype. These icons will be brightly lit when the above is true, else will remain dim. They are, from left to right:

EDIT mode

Toggle between EDIT and LIVE modes by pushing TAB.

The prompt now indicates the script you're currently editing:

Script 1 will be executed when trigger input 1 (top left jack on the panel) receives a low-to-high voltage transition (trigger, or front edge of a gate). Consider the following as script 1:

1:

TR.TOG A

Now when input 1 receives a trigger, TR.TOG A is executed, which toggles the state of output trigger A.

Scripts can have multiple lines:

1:

TR.TOG A
CV 1 V RAND 4

Now each time input 1 receives a trigger, CV 1 is set to a random volt between 0 and 4, in addition to output trigger A being toggled.

Metronome

The M script is driven by an internal metronome, so no external trigger is required. By default the metronome interval is 1000ms. You can change this readily (for example, in LIVE mode):

M 500

The metronome interval is now 500ms. You can disable/enable the metronome entirely with M.ACT:

M.ACT 0

Now the metronome is off, and the M script will not be executed. Set M.ACT to 1 to re-enable.

Patterns

Patterns facilitate musical data manipulation-- lists of numbers that can be used as sequences, chord sets, rhythms, or whatever you choose. Pattern memory consists four banks of 64 steps. Functions are provided for a variety of pattern creation, transformation, and playback. The most basic method of creating a pattern is by directly adding numbers to the sequence:

P.PUSH 5
P.PUSH 11
P.PUSH 9
P.PUSH 3

P.PUSH adds the provided value to the end of the list-- patterns keep track of their length, which can be read or modified with P.L. Now the pattern length is 4, and the list looks something like:

5, 11, 9, 3

Patterns also have an index P.I, which could be considered a playhead. P.NEXT will advance the index by one, and return the value stored at the new index. If the playhead hits the end of the list, it will either wrap to the beginning (if P.WRAP is set to 1, which it is by default) or simply continue reading at the final position.

So, this script on input 1 would work well:

1:

CV 1 N P.NEXT

Each time input 1 is triggered, the pattern moves forward one then CV 1 is set to the note value of the pattern at the new index. This is a basic looped sequence. We could add further control on script 2:

2:

P.I 0

Since P.I is the playhead, trigger input 2 will reset the playhead back to zero. It won't change the CV, as that only happens when script 1 is triggered.

We can change a value within the pattern directly:

P 0 12

This changes index 0 to 12 (it was previously 5), so now we have 12, 11, 9, 3.

We've been working with pattern 0 up to this point. There are four pattern banks, and we can switch banks this way:

P.N 1

Now we're on pattern bank 1. P.NEXT, P.PUSH, P, (and several more commands) all reference the current pattern bank. Each pattern maintains its own play index, wrap parameter, length, etc.

We can directly access and change any pattern value with the command PN:

PN 3 0 22

Here the first argument (3) is the bank, second (0) is the index, and last is the new value (22). You could do this by doing P.N 3 then P 0 22 but there are cases where a direct read/write is needed in your patch.

Check the Command Set section below for more pattern commands.

Patterns are stored in flash with each scene!

TRACKER mode

Editing patterns with scripts or from the command line isn't always ergonomic. When you'd like to visually edit patterns, TRACKER mode is the way.

The TAB key cycles between LIVE, EDIT and TRACKER mode. You can also get directly to TRACKER mode by pressing the NUM LOCK key. TRACKER mode is the one with 4 columns of numbers on the Teletype screen.

The current pattern memory is displayed in these columns. Use the arrow keys to navigate. Holding ALT will jump by pages.

The edit position is indicated by the brightest number. Very dim numbers indicate they are outside the pattern length.

Use the square bracket keys [ and ] to decrease/increase the values. Backspace sets the value to 0. Entering numbers will overwrite a new value. You can cut/copy/paste with ALT-X-C-V.

Scenes

A SCENE is a complete set of scripts and patterns. Stored in flash, scenes can be saved between sessions. Many scenes ship as examples. On startup, the last used scene is loaded by Teletype.

Access the SCENE menu using ESCAPE. The bracket keys ([ and ]) navigate between the scenes. Use the up/down arrow keys to read the scene text. This text will/should describe what the scene does generally along with input/output functions. ENTER will load the selected scene, or ESCAPE to abort.

To save a scene, hold ALT while pushing ESCAPE. Use the brackets to select the destination save position. Edit the text section as usual-- you can scroll down for many lines. The top line is the name of the scene. ALT-ENTER will save the scene to flash.

Keyboard-less Scene Recall

To facilitate performance without the need for the keyboard, scenes can be recalled directly from the module's front panel.

Init Script

The INIT script (represented as I) is executed when a preset is recalled. This is a good place to set initial values of variables if needed, like metro time M or time enable TIME.ACT for example.

Commands

Nomenclature

Syntax

Teletype uses prefix notation. Evaluation happens from right to left.

The left value gets assignment (set). Here, temp variable X is assigned zero:

X 0

Temp variable Y is assigned to the value of X:

Y X

X is being read (get X), and this value is being used to set Y.

Instead of numbers or variables, we can use operators to perform more complex behavior:

X TOSS

TOSS returns a random state, either 0 or 1 on each call.

Some operators require several arguments:

X ADD 1 2

Here ADD needs two arguments, and gets 1 and 2. X is assigned the result of ADD, so X is now 3.

If a value is returned at the end of a command, it is printed as a MESSAGE. This is visible in LIVE mode just above the command prompt. (In the examples below ignore the // comments).

8           // prints 8
X 4
X           // prints 4
ADD 8 32    // prints 40

Many parameters are indexed, such as CV and TR. This means that CV and TR have multiple values (in this case, each has four.) We pass an extra argument to specify which index we want to read or write.

CV 1 0

Here CV 1 is set to 0. You can leave off the 0 to print the value.

CV 1        // prints value of CV 1

Or, this works too:

X CV 1      // set X to current value of CV 1

Here is an example of using an operator RAND to set a random voltage:

CV 1 V RAND 4

First a random value between 0 and 3 is generated. The result is turned into a volt with a table lookup, and the final value is assigned to CV 1.

The order of the arguments is important, of course. Consider:

CV RRAND 1 4 0

RRAND uses two arguments, 1 and 4, returning a value between these two. This command, then, chooses a random CV output (1-4) to set to 0. This might seem confusing, so it's possible to clarify it by pulling it apart:

X RRAND 1 4
CV X 0

Here we use X as a temp step before setting the final CV.

With some practice it becomes easier to combine many functions into the same command.

Furthermore, you can use a semicolon to include multiple commands on the same line:

X RRAND 1 4; CV X 0

This is particularly useful in INIT scripts where you may want to initialize several values at once:

A 66; X 101; TR.TIME 1 20;

OPs and MODs

Variables

General purpose temp vars: X, Y, Z, and T.

T typically used for time values, but can be used freely.

A-D are assigned 1-4 by default (as a convenience for TR labeling, but TR can be addressed with simply 1-4). All may be overwritten and used freely.

OP OP (set) (aliases) Description
A A x get / set the variable A, default 1
B B x get / set the variable B, default 2
C C x get / set the variable C, default 3
D D x get / set the variable D, default 4
DRUNK DRUNK x changes by -1, 0, or 1 upon each read saving its state, setting will give it a new value for the next read
DRUNK.MIN DRUNK.MIN x set the lower bound for DRUNK, default 0
DRUNK.MAX DRUNK.MAX x set the upper bound for DRUNK, default 255
DRUNK.WRAP DRUNK.WRAP x should DRUNK wrap around when it reaches it's bounds, default 0
FLIP FLIP x returns inverted state (0 or 1) on each read (also settable)
I I x get / set the variable I, this variable is overwritten by L, but can be used freely outside an L loop
O O x auto-increments after each access, can be set, starting value 0
O.INC O.INC x how much to increment O by on each invocation, default 1
O.MIN O.MIN x the lower bound for O, default 0
O.MAX O.MAX x the upper bound for O, default 63
O.WRAP O.WRAP x should O wrap when it reaches its bounds, default 1
T T x get / set the variable T, typically used for time, default 0
TIME TIME x timer value, counts up in ms., wraps after 32s, can be set
TIME.ACT TIME.ACT x enable or disable timer counting, default 1
LAST x get value in milliseconds since last script run time
X X x get / set the variable X, default 0
Y Y x get / set the variable Y, default 0
Z Z x get / set the variable Z, default 0

DRUNK

Changes by -1, 0, or 1 upon each read, saving its state. Setting DRUNK will give it a new value for the next read, and drunkedness will continue on from there with subsequent reads.

Setting DRUNK.MIN and DRUNK.MAX controls the lower and upper bounds (inclusive) that DRUNK can reach. DRUNK.WRAP controls whether the value can wrap around when it reaches it's bounds.

O

Auto-increments by O.INC after each access. The initial value is 0. The lower and upper bounds can be set by O.MIN (default 0) and O.MAX (default 63). O.WRAP controls if the value wraps when it reaches a bound (default is 1).

Example:

O           => 0
O           => 1
X O
X           => 2
O.INC 2
O           => 3 (O increments after it's accessed)
O           => 5
O.INC -2
O 2
O           => 2
O           => 0
O           => 63
O           => 61

LAST

Gets the number of milliseconds since the current script was run. From the live mode, shows time elapsed since last run of I script.

For example, one-line tap tempo:

M LAST SCRIPT 

Running this script twice will set the metronome to be the time between runs.

Hardware

The Teletype trigger inputs are numbered 1-8, the CV and trigger outputs 1-4. See the Ansible documentation for details of the Ansible output numbering when in Teletype mode.

OP OP (set) (aliases) Description
CV x CV x y CV target value
CV.OFF x CV.OFF x y CV offset added to output
CV.SET x Set CV value
CV.SLEW x CV.SLEW x y Get/set the CV slew time in ms
IN Get the value of IN jack (0-16383)
PARAM PRM Get the value of PARAM knob (0-16383)
TR x TR x y Set trigger output x to y (0-1)
TR.POL x TR.POL x y Set polarity of trigger output x to y (0-1)
TR.TIME x TR.TIME x y Set the pulse time of trigger x to y ms
TR.TOG x Flip the state of trigger output x
TR.PULSE x TR.P Pulse trigger output x
MUTE x MUTE x y Disable trigger input x
STATE x Read the current state of input x

CV

Get the value of CV associated with output x, or set the CV output of x to y.

CV.OFF

Get the value of the offset added to the CV value at output x. The offset is added at the final stage. Set the value of the offset added to the CV value at output x to y.

CV.SET

Set the CV value at output x bypassing any slew settings.

CV.SLEW

Get the slew time in ms associated with CV output x. Set the slew time associated with CV output x to y ms.

IN

Get the value of the IN jack. This returns a valuue in the range 0-16383.

TR

Get the current state of trigger output x. Set the state of trigger output x to y (0-1).

TR.POL

Get the current polarity of trigger output x. Set the polarity of trigger output x to y (0-1). When TR.POL = 1, the pulse is 0 to 1 then back to 0. When TR.POL = 0, the inverse is true, 1 to 0 to 1.

TR.TIME

Get the pulse time of trigger output x. Set the pulse time of trigger output x to yms.

TR.TOG

Flip the state of trigger output x.

TR.PULSE

Patterns

Patterns facilitate musical data manipulation– lists of numbers that can be used as sequences, chord sets, rhythms, or whatever you choose. Pattern memory consists four banks of 64 steps. Functions are provided for a variety of pattern creation, transformation, and playback.

New in teletype 2.0, a second version of all Pattern ops have been added. The original P ops (P, P.L, P.NEXT, etc.) act upon the ‘working pattern’ as defined by P.N. By default the working pattern is assigned to pattern 0 (P.N 0), in order to execute a command on pattern 1 using P ops you would need to first reassign the working pattern to pattern 1 (P.N 1).

The new set of ops, PN (PN, PN.L, PN.NEXT, etc.), include a variable to designate the pattern number they act upon, and don’t effect the pattern assignment of the ‘working pattern’ (ex: PN.NEXT 2 would increment pattern 2 one index and return the value at the new index). For simplicity throughout this introduction we will only refer to the P ops, but keep in mind that they now each have a PN counterpart (all of which are detailed below)

Both patterns and their arrays of numbers are indexed from 0. This makes the first pattern number 0, and the first value of a pattern is index 0. The pattern index (P.I) functions like a playhead which can be moved throughout the pattern and/or read using ops: P, P.I, P.HERE, P.NEXT, and P.PREV. You can contain pattern movements to ranges of a pattern and define wrapping behavior using ops: P.START, P.END, P.L, and P.WRAP.

Values can be edited, added, and retrieved from the command line using ops: P, P.INS, P.RM, P.PUSH, P.HERE, P.NEXT, and P.PREV. Some of these ops will additionally impact the pattern length upon their execution: P.INS, P.RM, P.PUSH, and P.POP.

To see your current pattern data use the <tab> key to cycle through live mode, edit mode, and pattern mode. In pattern mode each of the 4 patterns is represented as a column. You can use the arrow keys to navigate throughout the 4 patterns and their 64 values. For reference a key of numbers runs the down the lefthand side of the screen in pattern mode displaying 0-63.

From a blank set of patterns you can enter data by typing into the first cell in a column. Once you hit <enter> you will move to the cell below and the pattern length will become one step long. You can continue this process to write out a pattern of desired length. The step you are editing is always the brightest. As you add steps to a pattern by editing the value and hitting <enter> they become brighter than the unused cells. This provides a visual indication of the pattern length.

The start and end points of a pattern are represented by the dotted line next to the column, and the highlighted dot in this line indicates the current pattern index for each of the patterns. See the key bindings for an extensive list of editing shortcuts available within pattern mode.

OP OP (set) (aliases) Description
P.N P.N x get/set the pattern number for the working pattern, default 0
P x P x y get/set the value of the working pattern at index x
PN x y PN x y z get/set the value of pattern x at index y
P.L P.L x get/set pattern length of the working pattern, non-destructive to data
PN.L x PN.L x y get/set pattern length of pattern x. non-destructive to data
P.WRAP P.WRAP x when the working pattern reaches its bounds does it wrap (0/1), default 1 (enabled)
PN.WRAP x PN.WRAP x y when pattern x reaches its bounds does it wrap (0/1), default 1 (enabled)
P.START P.START x get/set the start location of the working pattern, default 0
PN.START x PN.START x y get/set the start location of pattern x, default 0
P.END P.END x get/set the end location of the working pattern, default 63
PN.END x PN.END x y get/set the end location of the pattern x, default 63
P.I P.I x get/set index position for the working pattern.
PN.I x PN.I x y get/set index position for pattern x
P.HERE P.HERE x get/set value at current index of working pattern
PN.HERE x PN.HERE x y get/set value at current index of pattern x
P.NEXT P.NEXT x increment index of working pattern then get/set value
PN.NEXT x PN.NEXT x y increment index of pattern x then get/set value
P.PREV P.PREV x decrement index of working pattern then get/set value
PN.PREV x PN.PREV x y decrement index of pattern x then get/set value
P.INS x y insert value y at index x of working pattern, shift later values down, destructive to loop length
PN.INS x y z insert value z at index y of pattern x, shift later values down, destructive to loop length
P.RM x delete index x of working pattern, shift later values up, destructive to loop length
PN.RM x y delete index y of pattern x, shift later values up, destructive to loop length
P.PUSH x insert value x to the end of the working pattern (like a stack), destructive to loop length
PN.PUSH x y insert value y to the end of pattern x (like a stack), destructive to loop length
P.POP return and remove the value from the end of the working pattern (like a stack), destructive to loop length
PN.POP x return and remove the value from the end of pattern x (like a stack), destructive to loop length

P.N

get/set the pattern number for the working pattern, default 0. All P ops refer to this pattern.

P

get/set the value of the working pattern at index x. All positive values (0-63) can be set or returned while index values greater than 63 clip to 63. Negative x values are indexed backwards from the end of the pattern length of the working pattern.

Example:

with a pattern length of 6 for the working pattern:

P 10 retrieves the working pattern value at index 6

P.I -2 retrieves the working pattern value at index 4

This applies to PN as well, except the pattern number is the first variable and a second variable specifies the index.

P.WRAP

when the working pattern reaches its bounds does it wrap (0/1). With PN.WRAP enabled (1), when an index reaches its upper or lower bound using P.NEXT or P.PREV it will wrap to the other end of the pattern and you can continue advancing. The bounds of P.WRAP are defined through P.L, P.START, and P.END.

If wrap is enabled (P.WRAP 1) a pattern will begin at its start location and advance to the lesser index of either its end location or the end of its pattern length

Examples:

With wrap enabled, a pattern length of 6, a start location of 2 , and an end location of 8.

P.WRAP 1; P.L 6; P.START 2; P.END 8

The pattern will wrap between the indexes 2 and 5.

With wrap enabled, a pattern length of 10, a start location of 3, and an end location of 6.

P.WRAP 1; P.L 10; P.START 3; P.END 6

The pattern will wrap between the indexes 3 and 6.

If wrap is disabled (P.WRAP 0) a pattern will run between its start and end locations and halt at either bound.

This applies to PN.WRAP as well, except the pattern number is the first variable and a second variable specifies the wrap behavior (0/1).

P.I

get/set index position for the working pattern. all values greater than pattern length return the first step beyond the pattern length. negative values are indexed backwards from the end of the pattern length.

Example:

With a pattern length of 6 (P.L 6), yielding an index range of 0-5:

P.I 3

moves the index of the working pattern to 3

P.I 10

moves the index of the working pattern to 6

P.I -2

moves the index of the working pattern to 4

This applies to PN.I, except the pattern number is the first variable and a second variable specifics the index.

Control flow

OP OP (set) (aliases) Description
IF x: ... if x is not zero execute command
ELIF x: ... if all previous IF / ELIF fail, and x is not zero, execute command
ELSE: ... if all previous IF / ELIF fail, excute command
L x y: ... run the command sequentially with I values from x to y
W x: ... run the command while condition x is true
EVERY x: ... run the command every x times the command is called
SKIP x: ... run the command every time except the xth time.
OTHER: ... runs the command when the previous EVERY/SKIP did not run its command.
SYNC x synchronizes all EVERY and SKIP counters to offset x.
PROB x: ... potentially execute command with probability x (0-100)
SCRIPT SCRIPT x get current script number, or execute script x (1-8), recursion allowed
SCENE SCENE x get the current scene number, or load scene x (0-31)
KILL clears stack, clears delays, cancels pulses, cancels slews, disables metronome
BREAK BRK halts execution of the current script

IF

If x is not zero execute command

Advanced IF / ELIF / ELSE usage

  1. Intermediate statements always run

    SCRIPT 1:
    IF 0: 0        => do nothing
    TR.P 1         => always happens
    ELSE: TR.P 2   => else branch runs because of the previous IF
  2. ELSE without an IF

    SCRIPT 1:
    ELSE: TR.P 1   => never runs, as there is no preceding IF
  3. ELIF without an IF

    SCRIPT 1:
    ELIF 1: TR.P 1  => never runs, as there is no preceding IF
  4. Independent scripts

    SCRIPT 1:
    IF 1: TR.P 1    => pulse output 1
    
    SCRIPT 2:
    ELSE: TR.P 2    => never runs regardless of what happens in script 1
                       (see example 2)

L

Run the command sequentially with I values from x to y.

For example:

L 1 4: TR.PULSE I   => pulse outputs 1, 2, 3 and 4
L 4 1: TR.PULSE I   => pulse outputs 4, 3, 2 and 1

W

Runs the command while the condition x is true or the loop iterations exceed 10000.

For example, to find the first iterated power of 2 greater than 100:

A 2
W LT A 100: A * A A 

A will be 256.

EVERY

Runs the command every x times the line is executed. This is tracked on a per-line basis, so each script can have 6 different "dividers".

Here is a 1-script clock divider:

EVERY 2: TR.P 1
EVERY 4: TR.P 2
EVERY 8: TR.P 3
EVERY 16: TR.P 4

The numbers do not need to be evenly divisible by each other, so there is no problem with:

EVERY 2: TR.P 1
EVERY 3: TR.P 2

SKIP

This is the corollary function to EVERY, essentially behaving as its exact opposite.

OTHER

OTHER can be used to do somthing alternately with a preceding EVERY or SKIP command.

For example, here is a script that alternates between two triggers to make a four-on-the-floor beat with hats between the beats:

EVERY 4: TR.P 1
OTHER: TR.P 2

You could add snares on beats 2 and 4 with:

SKIP 2: TR.P 3

SYNC

Causes all of the EVERY and SYNC counters to synchronize their offsets, respecting their individual divisor values.

Negative numbers will synchronize to to the divisor value, such that SYNC -1 causes all every counters to be 1 number before their divisor, causing each EVERY to be true on its next call, and each SKIP to be false.

SCRIPT

Execute script x (1-8), recursion allowed.

There is a limit of 8 for the maximum number of nested calls to SCRIPT to stop infinite loops from locking up the Teletype.

SCENE

Load scene x (0-31).

Does not execute the I script. Will not execute from the I script on scene load. Will execute on subsequent calls to the I script.

WARNING: You will lose any unsaved changes to your scene.

Maths

Logical operators such as EQ, OR and LT return 1 for true, and 0 for false.

Metronome

An internal metronome executes the M script at a specified rate (in ms). By default the metronome is enabled (M.ACT 1) and set to 1000ms (M 1000). The metro can be set as fast as 25ms (M 25). An additional M! op allows for setting the metronome to experimental rates as high as 2ms (M! 2). WARNING: when using a large number of i2c commands in the M script at metro speeds beyond the 25ms teletype stability issues can occur.

Access the M script directly with alt-<F10> or run the script once using <F10>.

Just Friends

More extensively covered in the Just Friends Documentation.

OP OP (set) (aliases) Description
JF.TR x y Simulate a TRIGGER input. x is channel (0 = all) and y is state (0 or 1)
JF.RMODE x Set the RUN state of Just Friends when no physical jack is present. (0 = run off, non-zero = run on)
JF.RUN x Send a 'voltage' to the RUN input. Requires JF.RMODE 1 to have been executed, or a physical cable in JF's input. Thus Just Friend's RUN modes are accessible without needing a physical cable & control voltage to set the RUN parameter. use JF.RUN V x to set to x volts. The expected range is V -5 to V 5
JF.SHIFT x Shifts the transposition of Just Friends, regardless of speed setting. Shifting by V 1 doubles the frequency in sound, or doubles the rate in shape. x = pitch, use N x for semitones, or V y for octaves.
JF.VTR x y Like JF.TR with added volume control. Velocity is scaled with volts, so try V 5 for an output trigger of 5 volts. Channels remember their latest velocity setting and apply it regardless of TRIGGER origin (digital or physical). x = channel, 0 sets all channels. y = velocity, amplitude of output in volts. eg JF.VTR 1 V 4.
JF.TUNE x y z Adjust the tuning ratios used by the INTONE control. x = channel, y = numerator (set the multiplier for the tuning ratio), z = denominator (set the divisor for the tuning ratio).
JF.MODE x Set the current choice of standard functionality, or Just Type alternate modes. You'll likely want to put JF.MODE x in your Teletype INIT scripts. x = nonzero activates alternative modes. 0 restores normal.
JF.VOX x y z Create a note at the specified channel, of the defined pitch & velocity. All channels can be set simultaneously with a chan value of 0. x = channel, y = pitch relative to C3, z = velocity (like JF.VTR).
JF.NOTE x y Polyphonically allocated note sequencing. Works as JF.VOX with chan selected automatically. Free voices will be taken first. If all voices are busy, will steal from the voice which has been active the longest. x = pitch relative to C3, y = velocity.
JF.GOD x Redefines C3 to align with the 'God' note. x = 0 sets A to 440, x = 1 sets A to 432.
JF.TICK x Sets the underlying timebase of the Geode. x = clock. 0 resets the timebase to the start of measure. 1 to 48 shall be sent repetitively. The value representing ticks per measure. 49 to 255 sets beats-per-minute and resets the timebase to start of measure.
JF.QT x When non-zero, all events are queued & delayed until the next quantize event occurs. Using values that don't align with the division of rhythmic streams will cause irregular patterns to unfold. Set to 0 to deactivate quantization. x = division, 0 deactivates quantization, 1 to 32 sets the subdivision & activates quantization.

TELEXi Teletype Input Expander

The TELEXi (or TXi) is an input expander that adds 4 IN jacks and 4 PARAM knobs to the Teletype. There are jumpers on the back so you can hook more than one TXi to your Teletype simultaneously.

Inputs added to the system by the TELEX modules are addressed sequentially: 1-4 are on your first module of any type, 5-8 are on the second, 9-12 on the third, and so on. A few of the commands reference the module by its unit number – but those are rare.

TI.PARAM.MAP

If you would like to have a PARAM knob values over a specific range, you can offload the processing for this to the TXo by mapping the range of the potentiometer using the MAP command. It works a lot like the MAP operator, but does the heavy lifting on the TXi, saving you space in your code and cycles on your processor.

For instance, let's have the first knob return a range from 0 to 100.

TI.PARAM.MAP 1 0 100

You can reset the mapping by either calling the map command with the default range or by using the INIT command (TO.PARAM.INIT 1).

TI.PARAM.CALIB

You can calibrate your PARAM knob by using this command. The steps for full calibration are as follows:

  1. Turn the PARAM knob x all the way to the left
  2. Send the command 'TI.PARAM.CALIBRATE x 0'
  3. Turn the PARAM knob x all the way to the right
  4. Send the command 'TI.PARAM.CALIBRATE x 1'

Don't forget to call the TI.STORE command to save your calibration between sessions.

TI.IN.CALIB

You can calibrate your IN jack to external voltages by using this command. The steps for full calibration are as follows:

  1. Send a -10V signal to the input x
  2. Send the command 'TI.IN.CALIBRATE x -1'
  3. Send a 0V signal to the input x
  4. Send the command 'TI.IN.CALIBRATE x 0'
  5. Send a 10V signal to the input x
  6. Send the command 'TI.IN.CALIBRATE x 1'

Don't forget to call the TI.STORE command to save your calibration between sessions.

TELEXo Teletype Output Expander

The TELEXo (or TXo) is an output expander that adds an additional 4 Trigger and 4 CV jacks to the Teletype. There are jumpers on the back so you can hook more than one TXo to your Teletype simultaneously.

Outputs added to the system by the TELEX modules are addressed sequentially: 1-4 are on your first module of any type, 5-8 are on the second, 9-12 on the third, and so on. A few of the commands reference the module by its unit number – but those are rare.

Unlike the Teletype's equivalent operators, the TXo does not have get commands for its functions. This was intentional as these commands eat up processor and bus-space. While they may be added in the future, as of now you cannot poll the TXo for the current state of its various operators.

TO.TR.PULSE.DIV

The pulse divider will output one trigger pulse every y pulse commands. For example, setting the DIV factor to 2 like this:

TO.TR.P.DIV 1 2

Will cause every other TO.TR.P 1 command to emit a pulse.

Reset it to one (TO.TR.P.DIV 1 1) or initialize the output (TO.TR.INIT 1) to return to the default behavior.

TO.TR.WIDTH

The actual time value for the trigger pulse when set by the WIDTH command is relative to the current value for TO.TR.M. Changes to TO.TR.M will change the duration of TR.PULSE when using the WIDTH mode to set its value. Values for y are set in percentage (0-100).

For example:

TO.TR.M 1 1000
TO.TR.WIDTH 1 50

The length of a TR.PULSE is now 500ms.

TO.TR.M 1 500

The length of a TR.PULSE is now 250ms. Note that you don't need to use the width command again as it automatically tracks the value for TO.TR.M.

TO.TR.M.ACT

Each TR output has its own independent metronome that will execute a TR.PULSE at a specified interval. The ACT command enables (1) or disables (0) the metronome.

TO.TR.M.COUNT

This allows for setting a limit to the number of times TO.TR.M will PULSE when active before automatically disabling itself. For example, let's set it to pulse 5 times with 500ms between pulses:

TO.TR.M 1 500
TO.TR.M.COUNT 1 5

Now, each time we activate it, the metronome will pulse 5 times - each a half-second apart.

TO.TR.M.ACT 1 1

PULSE ... PULSE ... PULSE ... PULSE ... PULSE.

The metronome is now disabled after pulsing five times. If you call ACT again, it will emit five more pulses.

To reset, either set your COUNT to zero (TO.TR.M.COUNT 1 0) or call init on the output (TO.TR.INIT 1 1).

TO.TR.M.MUL

The following example will cause 2 against 3 patterns to pulse out of TO.TR outputs 3 and 4.

TO.TR.M.MUL 3 2
TO.TR.M.MUL 4 3
L 3 4: TO.TR.M.ACT I 1

TO.M.SYNC

This command causes the TXo at device d to synchronize all of its independent metronomes to the moment it receives the command. Each will then continue to pulse at its own independent M rate.

TO.CV.LOG

The following example creates an envelope that ramps to 5V over a logarithmic curve:

TO.CV.SET 1 V 5
TO.CV.LOG 1 2
TO.ENV.ATT 1 500
TO.ENV.DEC.S 1 2
TO.ENV.ACT 1 1

When triggered (TO.ENV.TRIG 1), the envelope will rise to 5V over a half a second and then decay back to zero over two seconds. The curve used is 2, which covers 0V-5V.

If a curve is too small for the range being covered, values above the range will be limited to the range's ceiling. In the above example, voltages above 5V will all return as 5V.

TO.OSC

Setting an OSC frequency greater than zero for a CV output will start that output oscillating. It will swing its voltage between to the current CV value and its polar opposite. For example:

TO.CV 1 V 5
TO.OSC 1 N 69

This will emit the audio-rate note A (at 440Hz) swinging from '+5V' to '-5V'. The CV value acts as an amplitude control. For example:

TO.CV.SLEW.M 1 1
TO.CV 1 V 10

This will cause the oscillations to gradually increase in amplitude from 5V to 10V over a period of one minute.

IMPORANT: if you do not set a CV value, the oscillator will not emit a signal.

If you want to go back to regular CV behavior, you need to set the oscillation frequency to zero. E.g. TO.OSC 1 0. You can also initialize the CV output with TO.CV.INIT 1, which resets all of its settings back to start-up default.

TO.OSC.RECT

The rectification command performs a couple of levels of rectification based on how you have it set. The following values for y work as follows: * y = 2: "full-positive" - inverts negative values, making them positive * y = 1: "half-positive" - omits all negative values (values below zero are set to zero) * y = 0: no rectification (default) * y = -1: "half-negative" - omits all positive values (values above zero are set to zero) * y = -2: "full-negative" - inverts positive values, making them negative

TO.OSC.SLEW

This parameter acts as a frequency slew for the targeted CV output. It allows you to gradually slide from one frequency to another, creating a portamento like effect. It is also great for smoothing transitions between different LFO rates on the oscillator. For example:

TO.CV 1 V 5
TO.OSC.SLEW 1 30000
TO.OSC.LFO.SET 1 1000
TO.OSC.LFO 1 100

This will start an LFO on CV 1 with a rate of 1000mHz. Then, over the next 30 seconds, it will gradually decrease in rate to 100mHz.

TO.OSC.CTR

For example, to create a sine wave that is centered at 2.5V and swings up to +5V and down to 0V, you would do this:

TO.CV 1 VV 250
TO.OSC.CTR 1 VV 250
TO.OSC.LFO 1 500

TO.ENV.ACT

This setting activates (1) or deactivates (0) the envelope generator on CV output y. The envelope generator is dependent on the current voltage setting for the output. Upon activation, the targeted output will go to zero. Then, when triggered (TO.ENV.TRIG), it will ramp the voltage from zero to the currently set peak voltage (TO.CV) over the attack time (TO.ENV.ATT) and then decay back to zero over the decay time (TO.ENV.DEC). For example:

TO.CV.SET 1 V 8
TO.ENV.ACT 1 1
TO.ENV.ATT.S 1 1
TO.ENV.DEC.S 1 30

This will initialize the CV 1 output to have an envelope that will ramp to +8V over one second and decay back to zero over thirty seconds. To trigger the envelope, you need to send the trigger command TO.ENV.TRIG 1. Envelopes currently re-trigger from the start of the cycle.

To return your CV output to normal function, either deactivate the envelope (TO.ENV.ACT 1 0) or reinitialize the output (TO.CV.INIT 1).

TO.ENV.EOR

The most important thing to know with this operator is that you can only cause the EOR trigger to fire on the same device as the TXo with the envelope. For this command, the outputs are numbered LOCALLY to the unit with the envelope.

For example, if you have an envelope running on your second TXo, you can only send the EOR pulse to the four outputs on that device:

TO.ENV.EOR 5 1

This will cause the first output on TXo #2 (TO.TR 5) to pulse after the envelope's attack segment.

TO.ENV.EOC

The most important thing to know with this operator is that you can only cause the EOC trigger to fire on the same device as the TXo with the envelope. For this command, the outputs are numbered LOCALLY to the unit with the envelope.

For example, if you have an envelope running on your second TXo, you can only send the EOC pulse to the four outputs on that device:

TO.ENV.EOC 5 1

This will cause the first output on TXo #2 (TO.TR 5) to pulse after the envelope's decay segment.

Advanced

Teletype terminology

Here is a picture to help understand the naming of the various parts of a Teletype command:

Teletype command terminology
Teletype command terminology
COMMAND

The entire command, e.g. IF X: Y 1; Z 2;.

PRE

The (optional) part before the PRE SEP, e.g. IF X.

POST

The part after the PRE SEP, e.g. Y 1; Z 2.

SUB

A sub command (only allowed in the POST), e.g. Y 1, or Z 2.

PRE SEP

A colon, only one is allowed.

SUB SEP

A semi-colon, that separates sub commands (if used), only allowed in the POST.

NUM

A number between −32768 and 32767.

OP

An operator, e.g. X, TR.PULSE

MOD

A modifier, e.g. IF, or L.

Sub commands

Sub commands allow you to run multiple commands on a single line by utilising a semi-colon to separate each command, for example the following script:

X 0
Y 1
Z 2

Can be rewritten using sub commands as:

X 0; Y 1; Z 2

On their own sub commands allow for an increased command density on the Teletype. However when combined with PRE statements, certain operations become a lot easier.

Firstly, sub commands cannot be used before a MOD or in the PRE itself. For example, the following is not allowed:

X 1; IF X: TR.PULSE 1

We can use them in the POST though, particularly with an IF, for example:

IF X: CV 1 N 60; TR.P 1
IF Y: TR.P 1; TR.P 2; TR.P 3

Sub commands can also be used with L, though due to (current) limitations on how many separate numbers, OPs and MODs are allowed in a single command this can be tricky (even if you can fit the text on a line).

Aliases

In general, aliases are a simple concept to understand. Certain OPs have been given shorted names to save space and the amount of typing, for example:

TR.PULSE 1

Can be replaced with:

TR.P 1

Where confusion may arise is with the symbolic aliases that have been given to some of the maths OPs. For instance + is given as an alias for ADD and it must be used as a direct replacement:

X ADD 1 1
X + 1 1

The key to understanding this is that the Teletype uses prefix notation2 always, even when using mathematical symbols.

The following example (using infix notation) will not work:

X 1 + 1

Aliases are entirely optional, most OPs do not have aliases. Consult the OP tables and documentation to find them.

Avoiding non-determinism

Although happy accidents in the modular world are one of it's many joys, when writing computer programs they can be incredibly frustrating. Here are some small tips to help keep things predictable (when you want to them to be):

  1. Don't use variables unless you need to.

    This is not to say that variables are not useful, rather it's the opposite and they are extremely powerful. But it can be hard to keep a track of what each variable is used for and on which script it is used. Rather, try to save using variables for when you do want non-deterministic (i.e. variable) behaviour.

  2. Consider using I as a temporary variable.

    If you do find yourself needing a variable, particularly one that is used to continue a calculation on another line, consider using the variable I. Unlike the other variables, I is overwritten whenever L is used, and as such, is implicitly transient in nature. One should never need to worry about modifying the value of I and causing another script to malfunction, as no script should ever assume the value of I.

  3. Use PN versions of OPs.

    Most P OPs are now available as PN versions that ignore the value of P.I. (e.g. PN.START for P.START). Unless you explicitly require the non-determinism of P versions, stick to the PN versions (space allowing).

  4. Avoid using A, B, C and D to refer to the trigger outputs, instead use the numerical values directly.

    As A-D are variables, they may no longer contain the values 1-4, and while this was the recommend way to name triggers, it is no longer consider ideal. Newer versions of the Teletype hardware have replaced the labels on the trigger outputs, with the numbers 1 to 4.

JF.MODE x Set the current choice of standard functionality, or Just Type alternate modes. You'll likely want to put JF.MODE x in your Teletype INIT scripts. x = nonzero activates alternative modes. 0 restores normal.
JF.NOTE x y Polyphonically allocated note sequencing. Works as JF.VOX with chan selected automatically. Free voices will be taken first. If all voices are busy, will steal from the voice which has been active the longest. x = pitch relative to C3, y = velocity.
JF.QT x When non-zero, all events are queued & delayed until the next quantize event occurs. Using values that don't align with the division of rhythmic streams will cause irregular patterns to unfold. Set to 0 to deactivate quantization. x = division, 0 deactivates quantization, 1 to 32 sets the subdivision & activates quantization.

JF.RUN x Send a 'voltage' to the RUN input. Requires JF.RMODE 1 to have been executed, or a physical cable in JF's input. Thus Just Friend's RUN modes are accessible without needing a physical cable & control voltage to set the RUN parameter. use JF.RUN V x to set to x volts. The expected range is V -5 to V 5
JF.SHIFT x Shifts the transposition of Just Friends, regardless of speed setting. Shifting by V 1 doubles the frequency in sound, or doubles the rate in shape. x = pitch, use N x for semitones, or V y for octaves.

JF.TR x y Simulate a TRIGGER input. x is channel (0 = all) and y is state (0 or 1)
JF.TUNE x y z Adjust the tuning ratios used by the INTONE control. x = channel, y = numerator (set the multiplier for the tuning ratio), z = denominator (set the divisor for the tuning ratio).
JF.VOX x y z Create a note at the specified channel, of the defined pitch & velocity. All channels can be set simultaneously with a chan value of 0. x = channel, y = pitch relative to C3, z = velocity (like JF.VTR).
JF.VTR x y Like JF.TR with added volume control. Velocity is scaled with volts, so try V 5 for an output trigger of 5 volts. Channels remember their latest velocity setting and apply it regardless of TRIGGER origin (digital or physical). x = channel, 0 sets all channels. y = velocity, amplitude of output in volts. eg JF.VTR 1 V 4.

TO.TR.M.SYNC x synchronizes the PULSE for metronome on TR output number x
TO.TR.POL x y sets the polarity for TR output n
TO.TR.PULSE x TO.TR.P pulses the TR value for output x for the duration set by TO.TR.TIME/S/M
TO.TR.PULSE.DIV x y TO.TR.P.DIV sets the clock division factor for TR output x to y
TO.TR.PULSE.MUTE x y TO.TR.P.MUTE mutes or un-mutes TR output x; y is 1 (mute) or 0 (un-mute)
TO.TR.TIME x y sets the time for TR.PULSE on output n; y in milliseconds
TO.TR.TIME.M x y sets the time for TR.PULSE on output n; y in minutes
TO.TR.TIME.S x y sets the time for TR.PULSE on output n; y in seconds
TO.TR.TOG x toggles the TR value for output x
TO.TR.WIDTH x y sets the time for TR.PULSE on output n based on the width of its current metronomic value; y in percentage (0-100)
TOSS randomly return 0 or 1
TR x TR x y Set trigger output x to y (0-1)
TR.POL x TR.POL x y Set polarity of trigger output x to y (0-1)
TR.PULSE x TR.P Pulse trigger output x
TR.TIME x TR.TIME x y Set the pulse time of trigger x to y ms
TR.TOG x Flip the state of trigger output x
V x converts a voltage to a value usable by the CV outputs (x between 0 and 10)
VV x converts a voltage to a value usable by the CV outputs (x between 0 and 1000, 100 represents 1V)
W x: ... run the command while condition x is true
WRAP x y z limit the value x to the range y to z inclusive, but with wrapping
WW.END x Set the loop end position (0-15)
WW.MUTE1 x Mute trigger 1 (0 = on, 1 = mute)
WW.MUTE2 x Mute trigger 2 (0 = on, 1 = mute)
WW.MUTE3 x Mute trigger 3 (0 = on, 1 = mute)
WW.MUTE4 x Mute trigger 4 (0 = on, 1 = mute)
WW.MUTEA x Mute CV A (0 = on, 1 = mute)
WW.MUTEB x Mute CV B (0 = on, 1 = mute)
WW.PATTERN x Change pattern (0-15)
WW.PMODE x Set the loop play mode (0-5)
WW.POS x Cut to position (0-15)
WW.PRESET x Recall preset (0-7)
WW.QPATTERN x Change pattern (0-15) after current pattern ends
WW.START x Set the loop start position (0-15)
WW.SYNC x Cut to position (0-15) and hard-sync the clock (if clocked internally)
X X x get / set the variable X, default 0
Y Y x get / set the variable Y, default 0
Z Z x get / set the variable Z, default 0
