My pick for this kind of job would be this box by Angelo Fraietta : http://www.users.bigpond.com/angelo_f/instruments.html
it has a lot of analog and digital ins and outs and the connectors are compatible with the i-cube sensors etc. The "Dumb Controller" can be set up via MIDI from your computer using a Max-like "boxes and wires" language. The "Smart Controller" has its own CPU and can be used at gigs and in installations without a PC.
The price is cheaper than most other boxes, I've seen.

hi all,
is there a way to read control voltage output in pd using a soundcard? what object should i use with adc~? can i simply plug the CV (maximum of 6 volts) to my soundcard or i need to buy an analog to digital
converter? Soundcards usually are capacitively coupled to their inputs, so the response drops off as the frequency drops below a few cycles per second, leaving no response at all for DC, which control voltage mostly is. One way around would be to pass the CV through an analog multiplexer that was rapidly switching between your CV and ground. If you know how to do electronics a bit you could use a 4052 analox mux and a 555 oscillator running about 1kHz to switch it. I would go for a PIC16F88 microcontroller, which has 7 10-bit ADC channels, outputting MIDI.
