Key Mode Alteration
Poly Mode or Mono Mode is an element that determines how to output the Upper and Lower Tones.
There are two ways of the The VC-1 can use either mode.
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.
