Opened a new project as well and tried with the controller and midi pattern. Went back to project I was working on too.
I played in the bass part and I have a synth part - both using the A-Pro. I've turned arp on and off, and have mix at 0%.
Here's a pedestrian question for ya! I've tried playing individual single notes, chords, patterns and I'm getting nothing. Loaded numbers of presets to include shapes and tried the above. No doubt its probably operator error, but can't figure it out even after two cups of coffee!
