Probably simple… increase pitch and speed…
Hi there. I’m new to this forum. I’ve created a simple looper from the MSP tutorial 14 for a simple drum rhythm loop. I want to increase the speed and pitch of the beat simultaneously over about a minute from say 70Hz to 440Hz and be able to set the rate at which they increase (perhaps exponentially). I’ve tried curve~ and line~ into the left inlet of groove~ but no joy. I want the repeating pattern to increase in rhythm and pitch, not just what’s in the buffer.
I would be very grateful for any help – I’m pretty new to this…
Not quite sure what you mean you want in the sentence, "I want the repeating pattern to increase in rhythm and pitch, not just what’s in the buffer." What do you want besides what’s in the buffer?
But if you just want to increase the pitch and tempo of what you’re looping, like speeding up a tape recorder, this approach works:

Hi Christopher, thanks for getting back to me. Sorry I haven’t replied sooner. That patch works great! Only I now realise I want to increase speed without increasing pitch (possibly by up to 3 or 400 times) Would you know a quick way to do this?
decorrelation of pitch and speed is commonly achieved using granular playback; look in Cycling74/examples/sampling/granular.
