When modulation is 0, the basic sawtooth waveform
will be produced, and when it is 99, a sawtooth wave
of double the frequency will be produced. If the
modulation value is a negative number, a different
effect will result than with positive settings.
Pulse wave
-98 -33 0
Waveform (pulse width) modulation will modify a
pulse waveform as shown below, creating time-variant
change in the sound. When modulation is 0, a square
wave will be produced, and when it is 99, the pulse
width will be 0, meaning that there will be no sound.
If the modulation value is a negative number, the
results will be inverted.
Triangle wave
-99 -25 0
Waveform modulation will modify a ramp wave as
shown below, creating time-variant change in the
sound. When modulation is 0, a triangle wave will
result, and as the modulation value increases, the
waveform will become a ramp wave (a waveform in
which the slope is broken in two). At a modulation
value of 50, a trapezoidal wave will result, and at a
value of 99 the waveform will once again be a triangle
wave. If the modulation value is a negative number,
the results will be inverted.Compared to sawtooth or
pulse waves, this waveform produces a strong
fundamental with fewer overtones, making it particu-
larly suitable for bass sounds etc.
1–3a: Wave
Main Wave
Selects the main waveform. Select either Saw
(sawtooth wave) or Pulse (pulse wave).
Level
Specifies the output level of the main waveform.
Wave Edge
Adjusts the amount of high-range overtones for the
main waveform. As the pitch rises, this effect will
become stronger, and in the low range there will be
little effect. Lower settings of this parameter will
produce a more mellow sound, and in the vicinity of 0
the volume will also decrease.
Triangle Level
Specifies the output level of the triangle waveform. It
will be output mixed with the main waveform.

Sine Level
Specifies the output level of the sine waveform. It will
be output mixed with the main waveform.
Phase Shift (Triangle & Sine Phase Shift)
Specifies the phase difference between the main
waveform and the triangle and sine waveforms. (The
triangle and sine waveforms will always be in phase
with each other.)
1–3b: Waveform (Waveform Modulation)
Waveform
Specifies the waveform. For the way in which this
value will affect the waveform, refer to the diagrams
shown on the previous page for sawtooth wave, pulse
wave, and triangle wave.
LFO
Selects the source LFO for waveform modulation.
LFO settings are made in the "Program P5."
Intensity (Waveform Modulation LFO Intensity)
Specifies the depth and direction of the waveform
modulation that will be controlled by the LFO
specified in "LFO."
AMS (Alternate Modulation Source)
Selects a modulation source ( p.48 of this manual)
that will control "Waveform."
Intensity (Waveform AMS Intensity)
Specifies the depth and direction of the waveform modula-
tion controlled by the "AMS." For negative settings, the
polarity of the modulation source will be inverted.
1–3c: Wave Shape
Input (Input Level)
Specifies the level of the signal that is input from the
standard oscillator to the wave shaping table.
