[sdiy] Midi continious controller gennerators / controler surfaces?

[Bret Truchan]

Hi Julian,

I might be able to help you out.  Unfortunatly, my solution isn't very 
mature.  How about using an Atmel AVR micocontroller to output the midi 
information?  I have a BASCOM (basic) program that I can give you that does 
that.  Using a rotary encoder (Digikey CT3001-ND) for your input would be 
slick.  I have bascom code that reads that rotary encoder, too.  If you 
don't like the rotary encoder idea, you could simply use the A/D converters 
on the AVR Microcontroller and use simple potentiometers instead. If you 
want a LOT of knobs and buttons, perhaps use an analog multiplexer, such as 
this one: Digikey 296-3517-5-ND.

I'm just throwing out ideas. :-)  The problem with my approach is that you'd 
need a programming board for the AVR Microcontroller, a compiler, such as 
BASCOM, and it would potentially be a lot of work.

Have you considered the Pocket Electronic from Doepfer?  It's listed in 
Doepfer's product page, at the bottom.  Here's some discussion about it:

Have fun!
