Son of a Pitch 1.1
The pitch of the incoming signal is controllable via 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.
