SYNC
SYNC refers to syncing the phases of two oscillators together. By syncing a VCO (slave) to another one
(master) the slave oscillator is forced to restart its cycle every time the master oscillator does. The
reset or hard sync happens when there’s a clear rising edge on the master VCO (picture 19). There’s
another type of sync called soft sync or flip that doesn’t reset the phase of the slave oscillator to the
start, rather it causes the oscillator to switch from the falling edge to the rising edge (or vice versa)
whenever there’s a rising edge on the master VCO (picture 20). Soft sync has a different sonic quality
and is able to produce some octave-switching effects when changing the relative pitch of the master
and slave oscillators.
Using SYNC can be a method to make sure that two slightly detuned oscillators produce the exact
same pitch without much timbral change to the slave oscillator. When detuning the slaved oscillator a
considerable amount (in reference to the master oscillator) this will result in a very distinctive timbre.
Most oscillators that have a SYNC input expect a SQUARE VCO to act as the master but VORTEX
accepts most waveshapes as long as the amplitude of the signals is high enough.
