Thank you very much, that seems to come up to my expectations ! I take advantage of this thread to explain my thoughts. I was thinking about, for instance, an electric guitar with a built-in ADC, that could be plugged in a computer via a USB (or Firewire) cable, the guitar being recognized as a 'snd-usb-audio' device under the system. With this view in mind, it might be useful to get many "digital" instruments like that, as well as a DAC, all available in a single JACK server. Will JACK2 be able to handle this ? I mean, you run jack2_start, and all the available (and desired) peripherals appear in the connections. :) I suppose that it raises many issues like synchronization between different physical peripherals. Handling many peripherals as separated devices might not be optimal compared to one single device with multiple inputs/outputs, as well. And actually I am not sure this idea is really essential... :) That was just a view of a weird future where several people plug all their USB guitar directly into a single computer, and do not even need to make use of a guitar amp. What a wonderful future of digital music I am painting here ! Forget it ! :D Adrien On Mon, Jul 28, 2008 at 4:01 PM, Paul Davis <paul@xxxxxxxxxxxxxxxxxxxxx> wrote: > > On Mon, 2008-07-28 at 14:59 +0200, Adrien DANIEL wrote: >> Hi ! >> >> I am wondering how to use JACK with more than one soundcard.
