UltraPitch is a formant-corrected pitch shifter with 6-voices. All pitch shifting is done with optional formant-correction to avoid the old chipmunk effect, or for excellent gender-bending.
Make a guy into a girl, or an alto sax into a tenor, etc. Each voice has independent stereo panning and delay, plus a little Animator delay-randomizer.
Set the pitchshift by musical intervals (with 5 cent resolution), plus the formant mapping can be fully manual or you can use the presets that perfectly match instrumental formant responses.
UltraPitch can create huge and thick stereo chorusing, doubling, parallel harmonies, excellent vocal slap/spread effects, and much more. The factory presets include classic setups for instruments, voices, plus some rather "outside the box" effects.
