The A-88 has four operating modes:
- Play Mode: This is the mode that is automatically selected when you power on the A-88. You can use the controllers (bender, d-beam, pedals, etc.) with their default settings.
- Function Mode: Press the FUNCTION button to enter this mode. You can then use the A-88 keyboard to make settings or transmit MIDI messages.
- SuperNATURAL mode: Press the SuperNATURAL button to enter this mode. SuperNATURAL mode sets the controllers on the A-88 to specific MIDI Controllers that match up with Roland's SuperNATURAL products (like the INTEGRA-7 sound module).
- MIDI Visual Control Mode: Hold FUNCTION and press the SuperNATURAL button to enter this mode. Entering this mode allows the A-88 to control video devices that support the MVC protocol.
