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, cutoff
frequency and volume to create modulation-type effects such as vibrato, wah and tremolo . Both LFOs have the same parameters .

Explanation
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 specified in the TVA
screen) .

Once the attack of the waveform output by the LFO is allowed to develop in standard fashion, the
waveform then continues without further change .

Trapezoidal wave
Sample & Hold wave (one time per cycle, LFO value is changed)
Chaos wave
Modified sine wave . The amplitude of a sine wave is randomly varied once each cycle .
A waveform generated by the data specified by LFO Step 1–64 . This produces stepped change with
a fixed pattern similar to a step modulator .
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
1 second (60/60 = 1 [second])
(half note)
0 .5 seconds (60/120 = 0 .5 [second])
(quarter note)
0 .25 seconds (60/240 = 0 .25 [second])
(eighth note)
NOTE
This setting will be ignored if the Waveform parameter is set to
LFO Rate Detune makes subtle changes in the LFO cycle rate (Rate parameter) each time a key is
pressed .
Higher settings will cause greater change . This parameter is invalid when Rate is set to
