Son of a pitch is an audio pitch bend effect. The pitch of the incoming signal can be controlled by the pitch knob or by a sync to host LFO. The pitch knob ranges from +3 octaves to -3 octaves of the original pitch. The effect also features an LFO controlled filter section. There are 3 filters to choose from, 2 SV filters and a butterworth filter. The filter section can be bypassed sending the dry signal straight to the pitch bender.
