8.3.5 OSC 2 PITCH MOD FADER
• The OSC 2 PITCH MOD fader controls the amount of PITCH MODULATION
applied to the OSC 2 SQUARE waveform. The PITCH MODULATION SOURCE
is selected in the OSC EDIT page described later in this section. Pitch
modulation is often used to create a vibrato eect, but can be used in many
other ways. The range of modulation is very wide, allowing both traditional
and creative modulations.
Controlling the frequency using an external signal is a form of frequency
modulation (FM), however as FM is more commonly used to describe the use
of an audio oscillator modulating another audio oscillator, the use the term
PITCH MODULATION is preferred in this instance.
Note: Because the DeepMind 12 LFO can reach well into the audio range, it
is possible to create traditional frequency modulation (FM) when the LFO is
used as the source for PITCH MODULATION of the OSCs.
The diagram below shows the waveforms obtained with LFO control of
OSC 2.
As you increase the amount of PITCH MODULATION, the variance in the pitch
of the oscillator will increase, resulting in larger increases and decreases as
demonstrated in the diagram below:

The OSC 2 PITCH MOD range is from 0.00 cents to 36.0 semitones, and the
default setting is 0.00 cents.
The OSC 2 PITCH MOD fader has a non-linear response which gives more
resolution at smaller settings, to allow delicate or ne use of the modulation.
The response of the OSC 2 PITCH MOD fader is shown below:
The fader position, current value, and stored value for the OSC 2 PITCH MOD
fader is shown on the PROG screen. There is also a visualization of the
waveform as shown below. The arrows indicate the polarity of the
waveform.
Note: for ENVELOPE sources, the arrow will only point in the UP direction
indicating that the base modulation will be positive from the base pitch.
Note: for Uni-polar LFO sources, the arrow will only point in the UP direction
indicating that the base modulation will be positive from the base pitch.
The default source for the pitch modulation is LFO1. For more information
on selecting the OSC 2 pitch modulation source in the OSC EDIT menu, please
consult the section later in this document.
