In addition to the dedicated pedal included with the GO:PIANO88 (GO-88P), Roland recommends the DP-2.
Connect the DP-2 while the GO-88P is powered off, and do not operate the pedal while the unit is starting up.
Regarding use with the Roland DP-10:
Due to a specification change, DP-10 units manufactured from February 2026 onward are not compatible with certain keyboards, including this model. For details, refer to "DP-10: The pedal does not respond despite being connected according to the instructions".
When using an older DP-10, set the function switch to the "Switch" position.
Note: Half pedaling is not supported.
