combination with the OSC 1 SQUARE waveform output.

8.3.4 SQUARE WAVEFORM SWITCH

ON=SQUARE
This switch controls the SQUARE waveform output for OSC 1.
The SQUARE waveform has a hollow sound, which does not sound as rich as
a sawtooth waveform due to the lack of even harmonics. Traditionally it is
often used to emulate a clarinet because of its similarity to the output of the
instrument. However in modern electronic music it is commonly used to thin,
nasal or cavernous sounds.
The SQUARE waveform contains a fundamental sine wave and its odd numbered
harmonics at a fi xed ratio. The level of each harmonic is the same as sawtooth
wave. I.e. the content of nth harmonic is 1/n, except there are no even numbered
harmonics present.
The characteristics of the SQUARE waveform are shown below:

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 eff 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 of an LFO signal
the term PITCH MODULATION is preferred in this instance.
Note: Because the DeepMind 12 LFO can reach well into the audio range
(1280 Hz) 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.
