A.When a BOSS EV-5 (or similar) expression pedal is connected to the RC-50, you can assign it to control a specific patch parameter, such as phrase volume, phrase pan, patch tempo, patch level, and others.

Note: You can't use the expression pedal to control a phrase's "original tempo" setting (the original tempo is set automatically during recording).
The volume and tempo can be controlled within the ranges shown in the following table.
Parameter range
Volume 0 - 200
Tempo 40 - 250
