PCM Synth Tone (PCMS)

Parameter Value Explanation
TVA Env Level 1–3 0–127
Specify the TVA envelope levels (Level 1–Level 3). These settings specify how the volume will
change at each point, relative to the standard volume (the Partial Level value specied in the TVA
screen).

* If you set TVA Env Level 3 near “0,” the sound may decay if you continue playing legato. If this
occurs, you can raise the TVA Env Level 3 value so that the sound continues.
Output tab
Output Level 0–127 Species the signal level of each partial.
Chorus Send Level 0–127 Species the level of the signal sent to the chorus for each partial.
Reverb Send Level 0–127 Species the level of the signal sent to the reverb for each partial.
LFO1/LFO2 tab
An LFO (Low Frequency Oscillator) causes change over a cycle in a sound. Each partial has two LFOs (LFO1/LFO2), and these can be used to cyclically change the pitch, cuto
frequency and volume to create modulation-type eects such as vibrato, wah and tremolo. Both LFOs have the same parameters.
Waveform
Selects the waveform of the LFO.
SIN Sine wave
TRI Triangle wave
SAW-U Sawtooth wave
SAW-D Sawtooth wave (negative polarity)
SQR Square wave
RND Random wave
BND-U
Once the attack of the waveform output by the LFO is allowed to develop in standard fashion, the
waveform then continues without further change.
NOTE
You must turn the Key Trigger parameter to “ON.” If this is “OFF,” it will have no eect.
BND-D
Once the decay of the waveform output by the LFO is allowed to develop in standard fashion, the
waveform then continues without further change.
NOTE
You must turn the Key Trigger parameter to “ON.” If this is “OFF,” it will have no eect.
TRP Trapezoidal wave
S&H Sample & Hold wave (one time per cycle, LFO value is changed)
CHAOS Chaos wave
VSIN Modied sine wave. The amplitude of a sine wave is randomly varied once each cycle.
STEP
A waveform generated by the data specied by LFO Step 1–64. This produces stepped change with
a xed pattern similar to a step modulator.
Rate
0–127, Note
Adjusts the modulation rate, or speed, of the LFO.
If you want the LFO rate to be synchronized with the tempo, specify the setting as a note value
relative to the synchronization tempo.
* You can control this parameter using the Matrix Control.
(Example) For a tempo of 120 (120 quarter notes occur in 1 minute (60 seconds))
Value LFO Rate
(half note)
1 second (60/60 = 1 [second])
(quarter note)
0.5 seconds (60/120 = 0.5 [second])
(eighth note)
0.25 seconds (60/240 = 0.25 [second])
NOTE
This setting will be ignored if the Waveform parameter is set to “CHAOS.”
