The Pitch Engines Bolt-on contains 2 extra pitch processing engines to boost capabilities of SFXEngine.

Arpeggiator will change the pitch of the sound between several selected pitches at a fixed rate. You can choose from 2 to 6 tones and the sequence will repeat. Can be used for many sorts of bleeps, chimes and signals. Modulate the speed for some unusual effects.

Pitch Modulator will change the pitch of the sound. Use it to shift the pitch of a sample or waveform. Modulate the pitch to produce vibrato or other more extreme audio effects.

For these pitch-only modulators, pitch changes affects all engines, not only the former ones, so the location of the engine is not important (all pitch effects are processed and summed in advance of other effects).
