Knob Lab

I connect it through Apple’s Audio Midi Setup and in Studio One and Pro Tools have it running Metric AB’s A/B switcher. Just have it sitting on a stand facing me and always on and push the knob when I want to switch to a different reference. Please add buttons and I’ll buy those too!

Firstly, I’ll explain why I gave this app four stars and what can be done to turn it into five stars: Add support for aftertouch and program changes! I use both of those frequently in my setup, so I would love to see them added as controllable knobs. Now for the main review. My MIDI keyboard only has one wheel and one slider for CC control, so I was looking for a cheap method to control more CC parameters without using my PC mouse in my DAW (which is too tedious for my liking). Then I had the idea to try looking for an app that could do that! I browsed through several paid apps until I found this free one that seemed to do exactly what I needed. Sure enough, it does, and it works really well!

Cool, but no way to add pitch bends. Hesitant to purchase Sonic Labs.
