What would be even better would be if someone can point me to a
kit I could build myself that I could hook up to a variable

continuous way (obviously there would be some sampling rate
involved).The attached schematic shows the simplest way I've found to make a
MIDI interface. The PIC 16F88 has 7 analog channels (pins RA4-0 and RB7
and 6) that could be interfaced to potentiometers of less than about 10kilohms for 10-bit resolution. If you have access to a PIC
programmer I can provide the code in an open-source way.Martin
Thanks Martin!
With all the work that I imagine goes into designing a custom MIDI
interface I usually just find some cheap MIDI keyboards on ebay and
chop them up, but then again I don't know much about MIDI.Maybe you can answer a couple of general questions for me?
Is MIDI capable of doing continuous stuff?
What is it's maximum sampling/transmission rate for MIDI?
Thanks for the schematic! I think what intimidated me most is the
interfacing of the software to the hardware: my C/C++ code is a bit
rusty... That schematic is pretty cool though! So many possabilities!
I think the Arduino will serve you very well for this. Its US$30
assembled and you can do what you want with it. You could do midi
with it if you really wanted, but I think MIDI mostly gets in the way
these days, unless you are using MIDI hardware like old synths, etc.

Looking at things from a more basic level, you can come up with a
more direct solution... It may sound small in theory, but it in
practice, it can change entire economies. - Amy Smith
