About MIDI
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 Switch (Control #066)
Messages which control sostenuto on/off.
Setting the value between 64 - 127 turns sostenuto on,
between 0 - 63 turns sostenuto off.
When notes are held before and during the time
sostenuto is turned on, those notes (and only those
notes) will be sustained until sostenuto is turned off.
Soft Pedal Switch (Control #067)
Messages which control soft pedal on/off.
Setting the value between 64 - 127 turns soft pedal on,
between 0 - 63 turns soft pedal off.
When soft pedal is on, the sound becomes softer and
lower in volume.
Harmonic Content (Control #071)
Messages which adjust the VCF resonance set for each
voice.
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.
Release Time (Control #072)
Messages which directly adjust the AEG release time set
for each voice.
Attack Time (Control #073)
Messages which directly adjust the AEG attack time set
for each voice.
Brightness (Control #074)
Messages which directly adjust the VCF cutoff fre-
quency set for each voice.
Lower values will result in a softer sound. Depending on
the voice, the effective range may be narrower than the
range available for adjustment.
Effect1 Depth (Reverb) (Control #091)
Messages which adjust the send level for the Reverb
effect.
Effect3 Depth (Variation Chorus) (Control #093)
Messages which adjust the dry/wet balance for the
Chorus Variation Effect.
Effect4 Depth (Variation Depth) (Control #094)
Messages which adjust the send level for the Variation
depth.
Data Increment (Control #096)
Decrement (Control #097) for RPN
Messages which increase or decrease the value of Pitch
Bend Sensitivity, Fine Tune, or Coarse Tune.
You must assign one of those parameters using the RPN
in the external device in advance.
RPN (Registered Parameter Number) LSB (Control
#100)
RPN (Registered Parameter Number) MSB (Control
#101)
Messages which offset, or add or subtract values from
the Pitch Bend Sensitivity, Fine Tune, or Coarse Tune
parameters.
First send the RPN MSB and RPN LSB to specify the
parameter which is to be controlled. Then use Data
Increment/Decrement to set the value of the specified
parameter.
Note that once the RPN has been set for a channel,
subsequent data entry will be recognized as the same
RPN’s value change. Therefore after you use the RPN,
you should set a Null (7FH, 7FH) value to avoid an
unexpected result.
Messages which can be transmitted are as follows:

Channel Mode Messages

All Sounds Off (Control #120)
Clears all sounds currently sounding on the specified
channel. However, the status of channel messages such
as Note On and Hold On is maintained.
Reset All Controllers (Control #121)
The values of the following controllers will be reset to
the defaults: Pitch Bend, Channel Pressure, Sustain
Switch, Modulation, Expression, Portamento, RPN*,
NRPN*, Volume, Pan.
* Number not specified; internal data will not change.
