Oh yea Alt outs yes.
This was a studio scenario and so Alt outs are my PFL listeners.
I got around the issue by re-recording back into a couple of channels back within Reaper.
BUT I should have used the QU stick in the desk. DUH!!!
However thats when I realised there is NO volume control anywhere for the out put of the 2 Track out.
See from what I gather you cant get back into the MAC from the master of the QU
Its a 32 by 32 USB …
Unlike the GSR24 where the master can record back into the Mac or PC
Anyhow….
cheers
