Nick and Arnold, Ok, so as you say jitter is too much important to use the solution given by Paul to my first post : using two different soundcards as input and output. Hence it is not possible, as I thought, to use the built-in (often low-quality and noisy, though) soundcard of a laptop computer, for example, as output. Ok, thank you. I precise that it was just an interrogation (about a potential commercial use), I personally use a single soundcard in full-duplex for my guitar. So, the solution would be a bit more complicated, but resembles what I proposed in my second post with USB : Firewire ADC for each instrument, and a Firewire DAC, such that everyone is kept synchronized. And I suppose that the number of Firewire ADC is also very limited by the number of Firewire busses.
