[Jack-Devel] Usage feasibility Q

Hi all, New to JACK wrt actual usage, I'm having a project which I want to setup as follows: 1. JACK in (hw:0,0) -> "JACK mixer" (This one should be as low a latency as possible, preferably 48 frames @48 Khz, i.e. 1ms buffer size) 2. Any-app-using-ALSA -> ALSA JACK plugin -> JACK "mixer" 3. JACK "mixer" -> JACK DSP plugin -> JACK out (hw:0,0) This will, in this particular case, run on a RPi3. Design goals are: One low latency route between input and output on a I2S sound card (1. above) and the rest of the applications using ALSA should share a higher latency route. The output of the JACK "mixer" should pass a JACK plugin before reaching hw:0,0. Before I get my hands too dirty I'd just like to ask if this architecture is feasible to do ? Regards /Robert
