To activate and deactivate Learn Mode, press the Store
and Tap/Cancel buttons simultaneously. The Store and
Tap/Cancel LEDs will light to indicate that Learn Mode is

knobs 5 to 20, press the Edit Pages to cycle to the desired
Edit Page.
The unit supports learned patches for Bypass and Tap, as
well as all available parameters controlled with the front
panel Edit knobs.

messages. This channel can be assigned in System Mode
with the MIDI Channel parameter.

The parameters controlled with the EDIT
knobs can be patched to Continuous
Controller messages.
