18 Oscillators Sequential
To use an LFO to sweep through the waves in a wavetable:
1. Use the
shape
knob on Oscillator 3 to select one of the 32 wavetables.
2. In the
lfo
section, press the
lfo
3 button, then the
destination
button.
3. In the display, choose
osc
3
shapemod
as the destination.
4. Hold down a note on the keyboard and listen as you set the
frequency
and
amount
of LFO 3 modulation as desired. Higher
frequency
settings
sweep through the wavetable faster. Higher
amount
settings sweep
though a wider range of waves in the wavetable.
Oscillator Parameters (Front Panel)
Shape:
Selects the waveshape generated by the oscillator. Oscillators 1
and 2 produce triangle, sawtooth, and pulse analog waveshapes. These
waveshapes are continuously variable. Oscillator 3 produces triangle,
sawtooth, super saw, and pulse waves, plus 32 wavetables containing 16
waves each .
Octave:
Sets the base frequency of an oscillator over a 5-octave range. The
global
master coarse
and
master fine
settings affect the pitch of the
oscillators. See “Global Settings” on page 119 for more information.
Pitch: -700...+699—
Fine tune control with a range of 7 semitones (a
major 5th) up or down. The 12 o’clock position is centered.
Shape Mod:
On Oscillator 1 and 2, this 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. On Oscillator 3, this knob selects a waveshape within the
currently selected wavetable. If
super saw
is selected as the waveshape,
shape mod
controls the thickness (detuning) of the Super Saw.
Applying waveshape modulation using an LFO or other modulation source in
the mod matrix is a great way to add movement to a sound.
