Having got up and crawling, if not running, with GA4 I have a weird issue that is perplexing me as I cannot find the solution.
My hardware is an Akai MPC (Elements version) and a Novation Impulse 61. I have the latest drivers for both installed.
The issue is this with MIDI control set to all MIDI inputs:
Groove Agent stand alone: doesn’t respond to Impulse, MIDI activity indicator comes on for the MPC, but nothing is triggered (pads are mapped correctly) and ‘edit/learn trigger note’ is greyed out.
Groove Agent in Reaper: Impulse works, MPC midi signals are seen by Reaper (and works with Addictive Drums), GA learns trigger notes but is not triggered.
Cubase Artist 9: Everything works.
The obvious answer is only to use Cubase, but alas the project I am working on with some friends is being done in Reaper . . and it would be quite useful to have the stand alone version work too.
