@weightless Hey, thank you! It worked to get rid of the click, but the pitch changes when changing start or end. I guess its because I recalculate the speed of the phasor when the loop changed (in the subpatch [pd compensateSpeed]) and this recalculation happens instantly. I tried to also put a [line~] object in between but still get the pitch-changes / wrong speed when cropping the sample

As my first pd-extended project I'm putting together a sample player / looper where you can crop the sample by specifying a start and end point. I have a crown envelope to avoid clicking when the loop restarts. Is there any way to avoid clicking when the sample position (start or end changed) is changed?
