You are right, indeed, that the controls listed are in the main window…and can be controlled by knob or fader.
However, there is not full overlap between the PlayBack page controls and the remote MIDI commands.
The point I meant to make earlier, which I still stand by, is that one cannot fully control the PU machines from direct remote/MIDI/control.
The MIDI spec (Appendix C) specifies that there are MIDI note-messages dedicated for PU machine (on active track), including
- combo Rec (doubling Rec1 button) input-specific record triggers, which become Overub and Replace depending on context.
- Play-stop (like Rec2) depending on context.
- the Multiply simply doubles the loop to be longer, but there is no way to divide/shorten the loop.
- controls for hands-free tack selection, Mute, Cue, and toggling Sync.
The remaining Playback controls of a PU are only MIDI’able by CC #16-21 to address the PlayBack page controls (Pitch, Direction, etc), to specific values. This makes things complicated, as some MIDI controllers can only button-switch between 0 and some value, where it would be better to have (more) dedicated macros or toggles between simpler controls.
Loopers come from a heritage of people with at least one hand full, and it’s really frustrating to have to set obtuse button-combinations or indirect MIDI mapping to do things that have classically been controlled directly by one-touch actions.
If they were able to add reception for PU-specific MIDI-note command like “Pickup Play/Stop” and “Multiply”, I don’t see why they could not (eventually) add dedicated one-touch MIDI actions for
- divide (cut loop in half)
- Replace (regardless of context, so it can have seperate action than OverDub)
- change direction (Forward/Reverse)
I used to own a Gibson EDP+, and the (more abundant) buttons were context dependent, but it was intuitive.
It is for the same reason that I’m presently doing most looping with a Boss RC202.
