During some "research", I found someone who built his own audio
interface:
http://www.em411.com/blog/3536/0/Live_SetsDIY_Interface.html

There's a video to watch in order to see it in action. It's quite
monome-like, but I guess it's not based on any of the DIY-kits. Would be
interesting to know where his idea came from.

ahh, i almost knew you were gonna post evans stuff before checking the 
link.  his original one is based on midibox (the one with the plexi-case 
and round buttons and knobs), the newer one with the bright square 
buttons i dont know but that one looks more monome-like.  ive been 
bugging him to consider OSC instead of midi since i got my box.

i know him online only, but he's a damn cool guy, he posted here once 
about buying a kit if i remember.

also, fwiw he posted his first box on the reaktor forum i think before 
the 40h was available, although im not sure the actual timeframe.  he 
originally was using a patch that was a modded version of one of my 
reaktor user lib patches, his setup was really cool when i saw videos 
and the patch itself, i dont know what hes doing box-wise now but he 
tells me he's working on some software for the Nintendo DS (music apps 
ala Nanoloop for the old GreyBrick Gameboy).

hey even, are you reading this?  keep up the great work!

also, i must say that while the Lemur interface originally was what got 
me into considering the monome (2-way control), it was Evan's machine 
that got me literally counting down the days till i could buy a 40h. his 
stuff is really inspiring.  as i said before, im a software guy, so i 
didnt have the guts to build one, so i thought the monome was the 
perfect compromise of custom interface meets lazy i-dont-want-to-solder 
mentality.

I thought someone else here might also be interested in his DIY-box. 
Sorry if the word "clone" made it sound like I assumed he made a "copy".
I just didn't find a suitable and short title for "this guy built 
something that reminds me of a monome, but with faders and knobs".

It was quite late when I stumbled over his page, so I didn't take the 
time to do some reading about the insides of his creation. Does he offer 
any information about how to make one of these?

wayyy back evan sent me info on the buttons he was using:

he also divulged that the early 16x16 prototype served as inspiration 
for his work, so, there you have it. he's done well adapting the idea to 
his performance.

rooker, clone isnt a bad word really, i was honestly just adding to what 
you said since i talk to him here and there over the past year or so. 
sorry if i came off wierd there!

like i said, his box is pretty cool, but i think he'd benifit alot from 
switching from the midi-based setup he uses now, especially someone that 
mainly uses reaktor, since reaktor's midi out, well, it leaves a bit to 
be desired, to politely understate it.  it's OSC implimentation isnt 
bad, though, except for the float-only thing.

im glad you posted the link here, i think alot of folks here would be 
interested, especially the kit folks.  also, im glad to see him get any 
exposure, i think its pretty cool the things he is doing (especially his 
first box, imo that one is just crazy looking, with all the knobs and 
the plexi case).  like i said, his first postings on the Reaktor forum 
with his controller videos (same one on the link) got me more excitied 
about the monome/40h than even the first links the people on the Reaktor 
forum posted to monome site itself.  it really shows well how a simple 
array of buttons and leds can be so limitless and liberating when you 
think about it (i before was comparing to the lemur, and while that 
thing is just amazing i think i stil prefer the monome's more open-ended 
(and open-source) angle towards the custom 2-way OSC-based controller).
