Synchronize ES2 oscillators
Typical oscillator sync sounds tend toward the aggressive, screaming leads that synthesizer
manufacturers like to talk about. The rectangular and sawtooth waveforms of oscillators 2
and 3 feature a Sync option. When this parameter is turned on, the phase of oscillator 2 or 3 is
synchronized with oscillator 1.
Every time oscillator 1 starts a new oscillation phase, the synchronized oscillator (oscillator 2
or 3) is also forced to restart its phase from the beginning. Between the waveform cycles of
oscillator 1, the waveform cycles of the synchronized oscillators run freely.
You can achieve interesting synchronized oscillator sounds by modulating the frequency of
the synchronized oscillator with an envelope generator. This constantly changes the number of
phases within a section of the synchronization cycle, resulting in corresponding changes to the
frequency spectrum.
Modulate the synchronized oscillator frequency with an envelope
1 Set the oscillator 2 Wave knob to Sync.
2 Set up a modulation routing as follows: modulation target Pitch2, source Env2.
3 Adjust the settings of Envelope 2.
