a friend of mine has been doing live delay line looping (from any input source) with pd, manipulating the time (length) and feedback on a delay and getting interesting looping-stretching-compressing effects from the feedback back into the delay.
My attempts in max have been unsuccessful so far and I am a little lost. He has been using an object called vd~ which is described below.
Is there something similar in max, or a way I can get the same sort of result through a delay line?
[vd~] implements a 4-point interpolating delay tap from a corresponding delwrite~ object. The delay in milliseconds of the tap is specified by the incoming signal.
