23 Prophet X User’s Guide Oscillators
To audition the oscillators:
1. Press the
global
button.
2. Use Soft Knob 1 to navigate to the
basic program
command, then press
Soft Key 1 (
write now
).
3. In the basic program, only Oscillator 1 is audible. (The level of Oscil-
lator 2 is set to zero and Instruments 1 and 2 do not have an instrument
selected.)
4. In the
oscillators
section, press the
shape
button to step through the
various waveshapes. Sawtooth is selected by default. Notice that it is
possible to select no waveshape.
5. As you toggle through the waveforms, turn the
shape mod
knob and
listen to how the timbre of the waveform changes. When
super saw
is
selected as the waveshape, this knob controls the thickness (detuning)
of the Super Saw wave.
6. Turn up the level of Oscillator 2 in the Mixer and experiment with
setting each oscillator to a different waveshape. Experiment with the
fine tune
knob on the oscillators and notice how slightly detuning the
oscillators in relation to each other creates movement and thickness in
their combined sound.
7. Try rotating the filter’s
cutoff
and
resonance
knobs to see how they
affect the sound of the oscillators.
8. Use the
pitch
knob to change the pitch (in semitones) of the oscillators.
Try tuning one oscillator to a interval such as a third, a fifth, or a sixth.
9. With both oscillators on, press the sync 2 > 1 button, then rotate the
pitch
knob on Oscillator 1 while you hold a note. This is the classic
hard sync sound. You can route an envelope to Oscillator 1 pitch using
the modulation matrix to create this effect each time you play a note.
You’ll learn more about the mod matrix in “Modulation” on page 55.
