The Volume knob on the Keyboard Controller Window (above the Pitch Wheel) keeps snapping back to the 11 o’clock position. I have no choice but to leave it there and use other volume controls to set the level.
Is this a bug or a feature? It feels like a bug.
[SOLVED]
The problem was caused by the Master Volume being mapped to MIDI CC7. This caused it to be triggered whenever the not E3 was played.
Other controls had CC mapping applied and I cleared them all. This applies to the Model 15 app and the Model D app running on MacOS.
I hope this post might help other users who encounter this problem.
