A Vocal Harmonizer is controlled via MIDI Note data received from the PSR540. Setting a MIDI Transmit Channel on the PSR540 to 'Upper' or 'Lower' enables either the Upper or Lower part of the Keyboard to control the Vocal Harmonizer.

NOTE: The Upper portion of the Keyboard consists of all keys to the right of the Split Point and the Lower portion consists of all keys below the Split Point.
