If you wish to use the A-Pro series controllers to control another MIDI device without being connected to a computer, you will need to set the MIDI I/F Switch setting to "OFF."
This setting (when set to "ON") normally routes the MIDI signal to the USB connection and a computer (if connected), where it can be routed by the computer application. By setting this to "OFF," the A-Pro series will route the MIDI signal directly to the MIDI OUT jack.
- Simultaneously press the ACT and ◀ button to enter EDIT mode.
- Use the Value Knob to select "MIDI Setting" on the screen, then press the Value Knob in to select this option.
- Use the Value Knob to select "MIDI I/F Switch" on the screen, then press the Value Knob in to select this parameter.
- Use the Value Knob to select "OFF" on the screen, then press the Value Knob in to confirm this setting.
You should now be able to use the A-Pro series controller to control another MIDI device directly.
