Expression Pedal Heel:  Pitch Mix = A10 + B0

Expression Pedal Toe:  Pitch Mix = A0 + B10

Scale-constrained intervals in two phase-offset loops (preset medium-long decay times).

Flex switch Learn modulates scale root notes for overdubs within the loops.

Expression pedal mixes loop input from A through B. The opposite side continues to loop.
