FEEDBACK:
One operator in each of the 8 algorithms has its output fed
back to its input. This is the feedback operator. The
amount of feedback applied can be adjusted over a range
of 0 to 7. By increasing the FEEDBACK level the harmon-
ics are increased, resulting in the generation of noise-like
sounds.

The Low Frequency Oscillator produces low-frequency
sine, saw-tooth or square waves, or a SAMPLE/HOLD
waveform. The LFO waveform can be used то арр!у vibrato,
tremolo ог "мом" effects to the voices. The amount of
LFO modulation applied can be controlled using the
modulation wheel, or breath controller once appropriate
WAVE,SPEED and DELAY parameters are set. (Refer to
page 26)
WAVE:
This selects the waveform output by the LFO. Any of the
six waveforms shown below can be selected.

SPEED:
The speed (frequency) of the LFO can be set from O to
99, O is the slowest L FO speed while 99 is the fastest.
DELAY:
This creates a delay between initial key closure and ap-
plication of LFO modulation. A setting of O results in no
delay — LFO modulation begins the instant a key is pressed
— and a setting of 99 creates the longest delay.
PMD/AMD:
Pressing this key alternately switches to PMD and AMD.

PMD (Pitch Modulation Depth):
Varies, over a O to 99 range, the depth of LFO modulation
applied to pitch. A O setting produces no pitch modulation,
and a setting of 99 produces maximum modulation.
The PMD function is separate from the effect of the con-
trollers, and can be used to apply vibrato effects that are
entirely independent of the controller settings.
AMD (Amplitude Modulation Depth):
Varies, over a O to 99 range, the depth of LFO modula-
tion applied to amplitude. A O setting produces no ampli-
tude modulation, and a setting of 99 produces maximum
modulation.
The AMD function is separate from the effect of the con-
trollers, and can be used to apply tremolo effects that are
entirely independent of the controller settings.
* MODULATION SENSITIVITY
MOD SENS.
PITCH/ AMP
This adjusts the sensitivity (depth) of pitch and amplitude
modulation. This parameter must be greater than O before
any amplitude or pitch modulation can be applied.
Be sure to check this parameter before using the modula-
tion wheel or other controllers.

PITCH:
Sensitivity to pitch modulation is variable from O to 7.
This value sets the modulation sensitivity for all oper-
ators. Applying pitch modulation results in vibrato type
effects.
