What is CONTROLLER mode?
In this mode, the [MIDI CH] button, [PGM CHANGE] button, and VALUE knob are assigned different functions than in the
normal PLAY mode.
To switch the A-500S to CONTROLLER mode...
If you simultaneously press the [MIDI CH] button and the [PGM CHANGE] button, the [MIDI CH] button and [PGM
CHANGE] button will light, and the A-500S will be in CONTROLLER mode.
If you again press the [MIDI CH] button and [PGM CHANGE] button simultaneously, the [MIDI CH] button and [PGM
CHANGE] button will go dark, and the A-500S will be in Normal PLAY mode.
* CONTROLLER mode works only in PLAY mode. It is not available in UTILITY mode.
