In the same way that FX, Groups and Mixes are available on the right-side of the Qu-Pad display, DCAs would be a real benefit here for faster access. Currently, if needing to reassign channels and move a DCA fader, it takes 3-4 user steps to locate and start adjusting, taking you away from the current view. With the quick access on the right calling the DCA fader to the master/focus fader position, you would keep your current view/layer. Example workflow:
Balancing lead and backing vocal levels with one another, realising the band needs taking down a bit with DCA 2, then wanting to add in a new vocal channel to DCA 1 in reality means leaving the vocal mics/their faders unattended while you switch layers. Although you could locate your DCA fader strips near/next to the input channels, this all uses up screen space. I find the typical outcome is I switch to using Groups instead, which are quicker to access and assign. However, this uses all four groups for Vox, Gtrs, Keys, Drums or similar just for control purposes unless intentionally wanting to process bussed signals. Groups are quite useful to keep aside for parallel processing or something like an ADT bus for guitars etc. hence why I’m trying to free them up again.
On an iPad Pro 12.9 there is plenty of space for this since the app scales, but for smaller iPads it would need to defer the space to groups and mixes. I appreciate this takes the interface of Qu-PAD further away from the physical layout of Q16/24/32 surfaces, but that’s probably not an issue(?).
