OPERATION Transmitting MIDI Messages To transmit MIDI messages, set the Mode Switch to the MIDI OUT position. Operation 1 The note number is transmitted when the corresponding key is pressed. Use the Octave Shift Switch, and select the position appropriate to the octave range you want. GZ-5 can send note numbers 17 to 108 but it has 32 keys only. Velocity is also transmitted when a key is pressed. GZ-5 sends the velocity in accordance with the selected position of the velocity switch.
Operation 2 The MIDI messages listed below are transmitted when completing the operation shown in the following table.
