5. MIDI OUT Connector – Use a five-pin MIDI cable to connect the MIDI
OUT of the Photon 25 to the INPUT of an external MIDI device.
The operation of the MIDI OUT port changes depending on whether or not a
USB cable is connected to the Photon.
● USB cable connected:
MIDI data from your computer is
passed to the MIDI OUT port.
Note: When a USB cable is
connected, you should activate
"MIDI echo" in your sequencer if
you want the Photon to control
another MIDI device.
● USB cable not connected:
Whatever you play on the
Photon is sent to the
MIDI OUT port.
Note: If you have another device
connected to the Photon's MIDI IN port, that device's MIDI
information will be ignored.
6. Sustain Pedal Input – Connect a keyboard sustain pedal (not included). Use
any manufacturer's sustain pedal: when you turn on the Photon 25, it will
automatically calibrate itself to the pedal.
