Pan (Control #010)
Messages which control the stereo panning position of
each voice (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
voice during performance.
Setting the value to 127 produces maximum volume
and 0 results in volume off.
Sustain Switch (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.
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
frequency 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 (Delay Depth) (Control
#094)
Messages which adjust the send level for the Delay
effect.
Data Increment (Control #096)
Decrement (Control #097) for RPN
Messages which increase or decrease the MSB value
of pitch bend sensitivity.
You must assign one of those parameters using the RPN
in the external device in advance.
The data byte is ignored.
When the maximum value or minimum value is
reached, the value will not be incremented or
decremented further. (Incrementing the fine tune will not
cause the coarse tune to be incremented.)
RPN (Registered Parameter Number)
LSB (Control #100)
RPN (Registered Parameter Number)
MSB (Control #101)
Messages which offset, or add or subtract values from
a voice's pitch bend sensitivity.
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 received are as follows:
RPN MSB RPN LSB
00 00
00 01
00 02
