The parameters is:
- Sawtooth wave: modification of the SPREAD parameter
-
Triangular wave: modification of the WRAP parameter
-
Square wave: modification of the WIDTH parameter
these parameters assume the following functions:
SPREAD: Defines the degree of deformation of the sawtooth waveform. If the parameter is
set with values above zero, the sound will be slightly out of tune; this effect will increase as
the value becomes higher.
WRAP: Defines the degree of deformation of the triangular waveform. In this case, the greater
the deformation, the more overtones are added to the sound generated by the signal.
WIDTH: sets the pulse width of the waveform. The trimmer can be turned to the minimum or
maximum setting to enrich the harmonic spectrum of the sound.

[FM]
(Frequency Modulation)
: defines the depth of the frequency modulation of the signal generated
by Osc.1 by the signal originating from the second oscillator. As the knob is turned clockwise,
the modulation depth increases. The resulting sound will be rich in overtones, suitable for
metallic timbres and sound effects.
In addition, you can obtain changes in tone without changing the pitch of Osc.1 by adjusting
the [FINE] and [RANGE] trimmers of the OSCILLATOR 2 section.
If the modulation is not noticeable enough, lower the slider [OSC1
ð
OSC2] of the OSCILLATOR
COMMON section.
