[PD] Virtual Mixer for Telematic Music

I just read a little while back that you can indeed use multiple adcs~ in
one patch, but no where is it explained for my particular case. I don't
want multiple adcs~ to route some channels here and some other channels
some where else. I need to be able to switch between 2 interfaces within
the same patch, so that I can use the same set of sliders to mix sound,
separately, either coming in from the internet via Jacktrip or locally via
my local interface.
What I would then do is, the output of the adc~ receiving audio channels
from Jacktrip over the internet will be routed to the dac~ to the local
sound, while the adc~ receiving audio channels from my local setup, should
be routed to some dac~ that will send the audio over Jacktrip to the remote
I'm not quite sure what you mean by crossfade. I just want to switch the
sliders in my patch to either control sound coming via jacktrip or to
control sound coming via my local interface, i.e. sound coming in from the
internet or sound coming in from local musicians.It has nothing to do with
timing between signals, just a switch between the incoming sets of audio.
The idea is to use the same set of 8 sliders to manage 8 channels either
coming in from Jacktrip or coming in from the local interface. I think the
term 'fader' is misleading; when I say fader I mean the sliders that one
finds on a mixer. I hope that makes my problem a little more clear :)
