Hello, does anyone know a good way to achieve changing the pitch and speed in real time, but separately? I’m planning to control them with 2 input devices (iphones wirelessly with the c74 object) Thanks!
Timo’s Grainstretch~ and DiraclE~ externals would be a good start. http://cycling74.com/forums/topic.php?id=37749
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.
GMEM’s bufgranul~ and livegranul~ are worth trying too.
[gizmo~] and [sig~] with appropriate locking back and forth as to whether the values affect each other:
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…
