One idea worth stealing for the Qu-Pad App would be the ability to select a Channel and be presented with a view of all of the send levels for that channel.
I work often as a monitor engineer. We usually have about ten minutes to change over from one band to the next. I usually start on stage right and work my way across, adjusting the level in four or five wedges for about a dozen channels. It’s easy to make a mistake when I to switch layers (mixes) back and forth.
It would be nice to have access to the dynamics for that channel in the same view too, but I don’t want to be greedy.
