	Allows the control of more than one Key message on one channel at a a time.
Poly Mode	The VC-1 is 16 or 8 voices polyphonic (depending on the patch used). So the Poly Mode
	can be used the VC-1 is controlled by a keyboard or sequencer.
	Allows only one MIDI massage on one channel. The VC-1 is 8 voices polyphonic using
	8 MIDI channels. The Mono mode is ideal for a MIDI Guitar System (GR-33, GR-20,
Mono Mode	etc.) hat has Mono mode, and transmits the messages of each string separately on a
	different channel. In the other words, Mono mode makes it possible to reproduce
	guitar sounds without spoiling the natural characteristics of the instrument.

Select Poly or Mono mode depending on the type of Mode Message sent from the external MIDI device.

When Mono mode messages are received by the VC-1, the messages can now be received on a channel

group (= eight consecutive MIDI channels, the basic channel being the lowest number).

*The Mono mode of the VC-1 allows it to receive only the note and bender messages for each channel, therefore it is NOT possible to set a different sound for each note separately.

When the VC-1 is being controlled by an external MIDI device, the Key mode selected in each Patch affects how the Tones are played and how the control messages run as shown in the following pictures.
