A rec button like the Rec on the dashboard. But the recording process should only concern mouse click / touch mouvements on control interface (only visible button, knobs, swicthes, list box, the process could also lock patches to avoid confusion). A sort of "automation record" with overdub. Then, a Play button to listen the result. If not satisfied, overdub the recording.
It could be a "on the fly" kind of recording, with no file to save to make it easy to implement.
Guess If i'm clear, I'm tired...
