hello
Are there any other Realtime pitch shifting objects abstractions externals than the one included in the documentation ???
the classic one, maybe the patch you saw : /pd/doc/3.audio.examples/56.delay.pitchshift.pd
frequency shifter : /pd/doc/3.audio.examples/52.ssb.modulation.pd
also, you can use some spectral techniques to do this with some modifications, you can turn the /pd/doc/4.fft.examples/11.pianorev.pd reverb patch to a pitch-shifter
