Switching the Memory of a MIDI-Compatible Pedal When You Switch Patches
For each patch, you can specify which memory of the MIDI-compatible pedal is selected.
Example
Outputting PC#1 (program number 1) when patch 01-1 is recalled
1. Choose a patch 01-1.
2. Press the [EDIT] button. In the eect chain screen, choose “CTL” with the [1] knob, and press the [ENTER] button.
3. Choose “PATCH MIDI1”–“PATCH MIDI4” with the [1]–[3] knobs, and press the [ENTER] button.
4. Use the [1] knob to set the MIDI CH.
* Set this to match the MIDI channel of the MIDI-compatible pedal that's connected.
5. Press the [PAGE >] button to switch the PAGE 2.
6. Use the [3] knob to set PC to “1.”
7. Press the [EXIT] button and [ENTER] button simultaneously, then execute the Write operation.

MEMO
If you want a CC (control change) to be transmitted simultaneously with the PC (program change), you can use PAGE 3 and PAGE 4 to specify
two dierent CC messages. For details, please refer to “Parameter Guide” (PDF).
