Hello, I would like to make a multi-channel USB sound card to serve as an interface between a software sequencer and a modular synthesizer. The number of channels would be 16 with possible extension by the ADAT protocol or other. Bandwidth is not essential since the signals sent will be of low frequency: LFO, ADSR, GATE. Which version of TEENSY should I use? Who would be interested in helping me out with the software part ? Thanks in advance to the volunteers !
