[PD] change the length of looped soundfile without audio-clicks

Hallo Frank, Hi pd-list,
hhhmmm...sorry I guess my explanation was not very precise.
I studied the pd-example-patches Frank mentioned but [samphold~] has a big disadvantage: if we change a start or stop point of a loop-playback, then this change will be executed only after each cycle of the [phasor~](thus when it jumps from 1 to again). But if we work with long soundfiles and want to change their length "on the fly"- from long loop length to short loop length for instance - then [samphold~] can*t do what we want.
So my question is:
How is it possible to change in real-time the start and stop position of a soundfile in loop mode without getting audible audio clicks.
Any other ideas, suggestions???

whenever I change the start and/or stop position in real-time I get a short

One popular approach is to use [samphold~] to only set the new limits
whenever the phasor~ jumps anyway. The samplers in 3.audio.examples
and Miller's book contain lots of examples of this approach.
