8.3 OSC
The Oscillators (OSCs) have a completely analog implementation. The signal path
of the waveform is purely analog circuitry. The pitch of these analog oscillators
is controlled digitally to ensure superior tuning accuracy and stability across the
entire range of playable notes.
• OSC 1 - This dual oscillator generates two dierent waveforms - one
SAWTOOTH, and one SQUARE. The waveforms can be used independently or
together to create harmonically rich content.
Features include pitch modulation of both the sawtooth and square
waveforms, and pulse width modulation of the square waveform.
• OSC 2 - This single oscillator generates a SQUARE waveform.
Features include pitch oset, independent level control, pitch modulation
and tone control modulation of the square waveform.
• NOISE - This generates a NOISE waveform. The NOISE generator is a
completely analog implementation and produces pink noise with a gentle
roll-o of lower frequencies.
8.3.1 OSC 1 PITCH MOD FADER
• The OSC 1 PITCH MOD fader controls the amount of PITCH MODULATION
applied to the OSC1 waveforms. 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 eect, but can be used in many other
ways. The range of modulation is very wide, allowing both traditional and
creative modulations.
Controlling the frequency by 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 the
term PITCH MODULATION is preferred in this instance.
Note: Because the DeepMind 6 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 1:
