Reply to Mapping question with loops...

The loop set and loop active commands do not appear to function if you press a button with them assigned, whilst your track is between a current loop start and loop end marker, whether or not the loop is active.

outside of a loop marker, it works as expected... And also, whilst INSIDE a current loop (but not active), the on screen 'active' loop button works, just not the midi control version (LOOP ACTIVE).
