I was doing sound at the ‘live’ stage of a psy-festival with a Qpac a couple of months ago.
We had two ipads - one to mix FOH and one to do monitors .
Its a pretty great little mixer ! and I think it would suit a large live-electronic setup pretty well.
I found the effects ok… the ‘dub delay’ was fucking terrible but hey maybe I just didn’t have time to get my head around it (but really its a dub delay how complicated can it be).
Also doing dub shots on an ipad isn’t fun.
Neither it trying to mix a 9 piece afro-beat band on an ipad (with…dodgy foldbacks). next year im trying to get them to hire a Qu32 or Qu24 console and only 1 ipad. ANYWAY
Qpac = all good in my books unless your mixing bands for 3 days
