24 Oscillators Dave Smith Instruments
Oscillator Parameters (Front Panel)
Shape: Sine, Sawtooth, Pulse, Super Saw —
This button selects the
waveshape generated by the oscillator. You can also turn the oscillator off
by selecting no waveshape.
Pitch:
Sets the base frequency of Oscillator 1 or 2 over a 9-octave range
from 16 Hz to 8 KHz (when used with the Transpose buttons). Adjustment
is in semitones. The global
master coarse
and
master fine
settings affect
the pitch of the oscillators. See “Global Settings” on page 119 for more
information.
Fine Tune: -50...+50
– Fine tune control with a range of a quarter tone up
or down. The 12 o’clock position is centered. Steps are in cents (50 cents =
1/2 semitone).
Shape Mod:
-64…+63 – Changes the “pulse” width of the selected
waveform, which modifies its harmonic content and timbre. To generate
a square wave when
pulse
is selected as the waveform, set this parameter
to 0. When
super saw
is selected as the waveshape,
shape mod
controls
the thickness (detuning) of the Super Saw.
Applying waveshape modulation using a low frequency oscillator or other
modulation source in the mod matrix is a great way to add movement and thickness to
a sound.
Sync 2>1: Off, On
—Turns Oscillator 1 hard sync on. Sync forces Oscillator
1 (the slave) to restart its cycle every time Oscillator 2 (the master) starts
a cycle. This provides a way to create more complex, harmonically rich
shapes from simple waveforms—especially when the frequency of Oscil-
lator 1 is set to a different interval than Oscillator 2.
