Modulation Wheel (Control Change #001)
The MIDI data produced when a modulation wheel is
operated. Setting the value to 127 produces maximum
vibrato and 0 results in vibrato off.
Portamento Time (Control Change #005)
Messages which control the duration of portamento, or a
continuous pitch glide between successively played notes.
Setting the value to 127 produces maximum portamento
time and 0 results in minimum portamento time. When the
parameter Portamento Switch (Control Change #065) is set
to on, the value set here can adjust the speed of pitch
change.
Data Entry MSB (Control Change #006)
Data Entry LSB (Control Change #038)
Messages which set the value for the parameter specified
by RPN MSB/LSB (page 182) and NRPN MSB/LSB (page
182). The value is represented by two control change data
numbers — the MSB and the LSB.
Main Volume (Control Change #007)
Sets the volume for each individual part. Setting the value
to 127 produces maximum volume and 0 results in volume
off.
Pan (Control Change #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 Change #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 Change #064)
Messages which control sustain on/off. Notes playing when
the pedal is pressed will be sustained. Setting the value
between 64 - 127 turns the sustain on, between 0 - 63 turns
the sustain off. While sustain is on, notes currently playing
will be sustained, even if Note Off messages are received.
n
The Half Damper function lets you finely control the length of
sustain over a range of 1 - 127, according to the depth at which
you press a continuous foot pedal.
Portamento (Control Change #065)
Messages which control portamento on/off. Setting the
value between 64 –127 turns the portamento on, and
between 0 - 63 turns the portamento off.
If portamento is turned on and the Mono/Poly parameter is
set to "mono," expressive legato play is possible. In other
words, when you play one note before releasing the next,
the pitch will glide smoothly from note to note, and the
envelopes (PEG, FEG and AEG) will stay in effect from note
to note — mimicking the natural behavior of acoustic
instruments. The speed of the pitch glide is determined by
the portamento time (Control Change #005).
Sostenuto Pedal (Control Change #066)
Messages which control sostenuto on/off. Setting the value
between 64 –127 turns the sostenuto on, between 0 - 63
turns the sostenuto 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.
Harmonic Content (Control Change #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.
Release Time (Control Change #072)
Messages which adjust the AEG release time set for each
Part. The value set here is an offset value which will be
added to or subtracted from the voice data.
Attack Time (Control Change #073)
Messages which adjust the AEG attack time set for each
Part. The value set here is an offset value which will be
added to or subtracted from the voice data.
Brightness (Control Change #074)
Messages which adjust the filter cutoff frequency set for
each Part. The value set here is an offset value which will
be added to or subtracted from the voice data.
Decay Time (Control Change #075)
Messages which adjust the AEG decay time set for each
Part. The value set here is an offset value which will be
added to or subtracted from the voice data.
Effect Send Level 1 (Reverb Depth)
(Control Change #091)
Specifies the reverb effect send level.
Effect3 Send Level 3 (Chorus Depth)
(Control Change #093)
Messages which adjust the send level for the Chorus
effect.
Data Increment (Control Change #096)
Data Decrement (Control Change #097)
Messages which increase or decrease the MSB value of
pitch bend sensitivity, fine tune, or coarse tune in steps of
1. You will need to assign one of those parameters using
the RPN in the external device in advance.
