PITCH SHIFTERS! What are your favorite? Zero-Latency, 64-bit?

Please tell me what your favorite pitch shifters are!

I'm X1d Build 535 64-bit on Windows 7 + every ProChannel plugin . . . but Cakewalk's standard pitch shifter is still 32 bit with a compensated delay.


Unfortunately, there's a bass drum I want to pitch down 4 semitones and the compensated latency of Cakewalk's Pitch Shifter messes up the tempo, even if I freeze the track and then bounce the FX to the WAV file.


Please tell me what your favorite pitch shifters are, preferably zero-latency and 64-bit!
