Not sure if your speaking to me
I’m gonna answer anyways 
So I have an nw2s::o16 that brings 16 channels for the modular to channel 1-16 on my audio interface (via a patchbay in normal configuration). Channels 17-24 are also from a 8 normaled channels on the same patchbay, default input is a few reverbs, an iPad over soundcard and a synth. Another patchbay allows reconfiguration, like splitting various of the euro channels into reverbs.
So nothing’s really set I’m stone, but while patching i just send things more or less arbitrary into a free input on the o16 and possibly reconfigure the patchbays to send to the reverbs. But when I press record in the saw, i want to record all 24 channels, which will be everything…
And nothing is preconfigured in my case, except the addac manual latches that I interpret as mutes in the teletype + 301…
If question was not directed to me, feel free to disregard entirely
