Channel Message
4 Channel Message Overview
4.1 Send Channel
For information about the MIDI channels of the channel messages that are sent when this Instrument
is played, see
1.2.3
Part Assignments . Note, however, that the MIDI channel of the performance
information that corresponds to the keyboard main part can be changed by the Keyboard Channel
setting value.
4.2 Receive Channel
For information about the MIDI channel numbers of channel messages received by each part, see
1.2.3
Part Assignments . The MIDI channel number of a channel message that changes DSP settings also
coincides with the MIDI channel of the part using the DSP. A channel message is not received by a part
that is turned off by the Part Enable Parameter value explained under
19.6
Part Parameter .
4.3 Instrument Velocity Resolution
The upper seven bits of the 14-bit resolution correspond to the Note On/Off message, while the lower
seven bits correspond to the High Resolution Velocity Prefix message. (Note1)
Note On/Off High Resolution Velocity Prefix
Upper 7 bits
Lower 7 bits
14bits
The initial default value for the lower 7 bits is 00H. Receipt of a High Resolution Prefix message
causes the lower seven bits to be set, but note on/off is not performed.
Receipt of a Note On/Off message causes the upper seven bits to be set with note on/off performed
with 14-bit resolution Velocity.
The High Resolution Velocity Prefix message corresponds the message immediately following the Note
On/Off message, and the lower seven bits are cleared to 00H immediately following note on/off by the
Note On/Off message. 7-bit resolution note on/off using only the Note On/Off message also continues
to be supported.
For details about each message, see ”
