58 DeepMind 12D User Manual • SLEW-RATE - This option allows you to smooth out the transitions of the LFO 8.3 OSC waveform. The SLEW RATE reduces the rate of change of the LFO waveform shape. The Oscillators (OSCs) have a completely analog implementation. The signal path of the waveform is purely analog circuitry. The pitch of these analog oscillators LFO SLEW RATE is controlled digitally to ensure superior tuning accuracy and stability across the entire range of playable notes. 0 • OSC 1 - This dual oscillator generates two different waveforms - one 85 SAWTOOTH, and one SQUARE. The waveforms can be used independently or together to create harmonically rich content. 170 Features include pitch modulation of both the sawtooth and square 255 waveforms, and pulse width modulation of the square waveform. • OSC 2 - This single oscillator generates a SQUARE waveform. The SLEW RATE range is from 0-255, with 0 being no change, and 255 full smoothing. Features include pitch offset, independent level control, pitch modulation and tone control modulation of the square waveform. The default SLEW RATE setting is 0. • PHASE - As each voice has independent LFOs, this option allows you to control the phase relationship between the LFO waveforms. • NOISE - This generates a NOISE waveform. The NOISE generator is a completely analog implementation and produces pink noise with a gentle roll-off of lower frequencies. • POLY - All voices use an independent LFO. This is the default mode. • MONO - All voices use a common LFO. • SPREAD - With a setting of 1, there is a 1 degree shift between the LFOs for each voice. As you begin to increase the SPREAD value, the phase of the LFO for each consecutive voice will be shifted by the amount of SPREAD applied. For example, with a 90 degree setting, the first voice will always be at 0 degrees, and each consecutive voice will be shifted by an additional 90 degrees. So with 4 voice UNISON, voice 1 would be at 0 degrees, voice 2 would be at 90 degrees, voice 3 would be at 180 degrees, and voice 4 would be at 270 degrees.

waveform. The SLEW RATE reduces the rate of change of the LFO
waveform shape.
The SLEW RATE range is from 0-255, with 0 being no change, and 255 full

The default SLEW RATE setting is 0.

- All voices use an independent LFO. This is the default mode.

- All voices use a common LFO.
•
SPREAD
- With a setting of 1, there is a 1 degree shift between the LFOs
for each voice. As you begin to increase the SPREAD value, the phase of
the LFO for each consecutive voice will be shifted by the amount of
SPREAD applied. For example, with a 90 degree setting, the first voice

by an additional 90 degrees. So with 4 voice UNISON, voice 1 would be
at 0 degrees, voice 2 would be at 90 degrees, voice 3 would be at 180
degrees, and voice 4 would be at 270 degrees.
The PHASE SPREAD range is from 1-254 degrees.
The default PHASE setting is POLY.

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 effect, 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 12D 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.
