I’m planning to control them with 2 input devices (iphones wirelessly with the c74 object) Thanks!

does ‘in real time’ mean live audio input? Cos ya can’t vary speed in real time!! Only retrospectively; and pitch modulation will also introduce some latency, as frequency is a function of time. That said, granulation may well be the way to go, but consider a delay line as well.

change pitch only: gizmo~ value changes
change speed and pitch, locked: change sig~ only
to change speed without changing pitch: value for sig~ –> [!/ 1.] (reciprocal) –> value for gizmo~

so for example, 2.0 speed –> 0.5 pitch (drop an octave, back to original pitch)

only sounds good for a limited range depending on the fft~ size, but that’s a limitation of any pitch-shifting.

extreme values in one or both of these can sound pretty awesome…
