Event-based pitch shifter

Chops audio into individual beats and shifts each beat downwards in pitch. Only allowing downwards shifts helps keep timing very tight - depending on complexity, whole rhythm sections can be shifted!

Tune Coarse tune (semitones)
Fine Fine tune (cents)
Decay Adjust envelope of each chunk (a fast decay can be useful while setting up)
Thresh Trigger level to divide the input into chunks
Hold Minimum chunk length
Mix Mix original signal with output
Quality The High setting uses smoother pitch-shifting and allows processing of stereo signals

Alternative uses include a triggered flanger or sub-octave doubler (both with mix set to 50% or less) and a swing quantizer (with a high threshold so not all beats trigger).
