I currently have a two knobs on my Akai MPK25 to control a pair of sends (Guitar and Vocal) to my monitors but this is the only thing I really use that keyboard for, so I'd like to remove it from my rig.
I use the Duet app to display MS3 on my mic-stand-mounted iPad but find it a bit finicky to make small changes to these sends via on-screen knobs. Is there any way to make +/- buttons that would change those levels by something like 0.2 dB per press?
MacBook Pro with Retina display, OS X El Capitan (10.11.1)
