5.2.3. Pulse Width
This knob affects only the square wave of VCO 1. It has no impact on the saw or triangle
waveforms. What it does is alter the width of the square wave from a "round-sounding" 50%
to increasingly narrow-sounding pulse waves. See the Signal enhancers [p.48] section of the
Basic Synthesis [p.46] chapter for a visual representation of the waveforms.
The Pulse Width can be modulated by an LFO or other sources via the patch bay. See the
PWM [p.31] section for more information and related links to other chapters.

♪ : The setting of the Pulse Width knob does not affect the square wave of VCO 2.
5.2.4. Metalizer
This knob affects only the triangle wave of VCO 1. It has no impact on the saw or square
waveforms. The
Metalizer
takes the peaks of the basic triangular waveform and “folds”
them downward to create very complex jagged waveforms that are rich in high harmonics.
See the Signal enhancers [p.48] section of the Basic Synthesis [p.46] chapter for a visual
representation of the waveforms.
5.2.5. FM
FM stands for Frequency Modulation. This knob affects all three waveforms of VCO 1 at
the same time. By default the FM source is VCO 2, so the frequency of that oscillator will
modulate the frequency (pitch) of VCO 1 as the value of this knob is increased.
When range switch of VCO 2 is set to LFO the frequency modulation will sound more like
vibrato. But when it is set to Fine or All the frequencies of VCO 2 are so high that they will
cause a significant disruption to the waveforms being generated by VCO 1. The resultant
sound can be clangorous (bell-like) or somewhat noisy depending on the frequencies and
waveforms involved.
5.2.6. Ultrasaw Amt
This knob affects only the sawtooth wave of VCO 1. It has no impact on the square or
triangle waveforms. An increase in its value will mix the original sawtooth wave with
two phase-shifted copies of itself, resulting in a fatter sound. The result is different in
character than that of detuned sawtooth waveforms being generated by two different VCOs.
See the Signal enhancers [p.48] section of the Basic Synthesis [p.46] chapter for a visual
representation of the waveforms.
5.2.7. PWM
The Pulse Width of the square wave can be modulated by a source such as LFO 1 (the pre-
wired default) or another source via the patch bay [p.58] . See the Signal enhancers [p.48]
section of the Basic Synthesis [p.46] chapter for a visual representation of the waveforms.
