Try using the auxiliary envelope to sweep the pitch of Oscillator 1 when it is
synced to generate the classic, hard-edged sync sound.

Sub Octave: 0...127—
pitched one octave below Oscillator 1. Adding a sub octave to sounds
such as bass is a great way to increase low-register presence.
—Enables the outputs of oscillators 1 and 2 to be mixed

in varying amounts. A setting of 0 is equivalent to 100% Oscillator 1
and 0% Oscillator 2. A setting of 127 is the opposite. A setting of 64 is a
50-50 mix of both oscillators.
0...127 – Sets the output level of the white noise generator.

0...127 – Adds randomized detuning to the oscillators to
Osc Slop:
emulate the tuning instability of vintage analog oscillators. This tuning
instability is a big part of what made vintage instruments sound charac-
teristically warm and fat. The oscillators in the Prophet Rev2 are very
stable, and will not drift. Use parameter to dial in as little or as
osc slop
much drift as you like.
