CHANNEL MESSAGES
Channel messages contain data related to the performance
on the keyboard for the specific channel.
■ Note On/Note Off (Key On/Key Off)
Messages which are generated when the keyboard is played.
Reception note range = C-2 (0) - G8 (127), C3 = 60
Velocity range = 1 - 127 (Only the Note On velocity is
received)
Note On: Generated when a key is pressed.
Note Off: Generated when a key is released.
Each message includes a specific note number which
corresponds to the key which is pressed, plus a velocity value
based on how hard the key is struck.
■ Control Change
Control Change messages let you select a voice bank, control
volume, panning, modulation, portamento time, brightness
and various other controller parameters, through specific
Control Change numbers which correspond to each of the
various parameters.
Bank Select MSB (Control #000)
Bank Select LSB (Control #032)
Messages which select variation voice bank numbers by
combining and sending the MSB and LSB from an
external device. The functions of MSB and LSB messages
differ depending on the tone generator mode. MSB numbers
select voice type (Normal Voice or Drum Voice), and LSB
numbers select voice banks.
(For more information about Banks and Programs, see Voice
List in the separate Data List.)
A new bank selection will not become effective until the next
Program Change message is received.
Modulation (Control #001)
Messages which control vibrato depth using the Modulation
Wheel.
Setting the value to 127 produces maximum vibrato and 0
results in vibrato off.
Portamento Time (Control #005)
Messages which control the duration of portamento, or a
continuous pitch glide between successively played notes.
When the parameter Portamento Switch (Control #065) is set
to on, the value set here can adjust the speed of pitch
change.
Setting the value to 127 produces maximum portamento time
and 0 results in minimum portamento time.
Data Entry MSB (Control #006)
Data Entry LSB (Control #038)
Messages which set the value for the parameter specified by
RPN MSB/LSB (page 183) and NRPN MSB/LSB (page 183).
Parameter value is determined by combining the MSB and
LSB.
Main Volume (Control #007)
Messages which control the volume of each Part.
Setting the value to 127 produces maximum volume and 0
results in volume off.
Pan (Control #010)
Messages which control the stereo panning position of each
Part (for stereo output).
Setting the value to 127 positions the sound to the far right
and 0 positions the sound to the far left.
Expression (Control #011)
Messages which control intonation expression of each Part
during performance.
Setting the value to 127 produces maximum volume and 0
results in volume off.
Hold1 (Control #064)
Messages which control sustain on/off.
Setting the value between 64 - 127 turns the sustain on,
between 0 - 63 turns the sustain off.
Portamento Switch (Control #065)
Messages which control portamento on/off.
Setting the value between 64 -127 turns the portamento on,
between 0 - 63 turns the portamento off.
Sostenuto (Control #066)
Messages which control sostenuto on/off.
Holding specific notes and then pressing and holding the
sostenuto pedal will sustain those notes as you play
subsequent notes, until the pedal is released.
Setting the value between 64 -127 turns the sostenuto on,
between 0 - 63 turns the sostenuto off.
Harmonic Content (Control #071)
Messages which adjust the filter resonance set for each Part.
The value set here is an offset value which will be added to or
subtracted from the voice data. Higher values will result in a
more characteristic, resonant sound. Depending on the voice,
the effective range may be narrower than the range available
for adjustment.
