Hello!

I'm working on an audio looper that will stretch based on BPM changes detected by Ableton Link. Not sure if this is remotely the best way to go about things but the project I'm using this in is quite noisy and therefore what might be unacceptable to some might be exciting to us, and perhaps you as well.

Astute readers of this forum may detect that I have lifted solutions from this thread: https://forum.pdpatchrepo.info/topic/6403/timestretch-abstractions

This is a proof of concept for now and I will update as things get more ironed out. Enjoy!

I have used @xbarbie's solution for years and while it works perfectly for text files it does not work well with larger audio files on my raspberry pi. If you have hcs available and you want a different solution I have this abstraction that takes symbol input and outputs a 1 or 0 just like @xbarbie's. Relative paths work as well.

Oh my goodness thank you @whale-av for the contribution to such an old thread. I figured out how to integrate poly 1 1 as mentioned above and my solution looks like this:

Hopefully this and your patches help anyone who comes along in the future.

I'm personally still trying to figure this out. Does anyone know how to integrate poly 1 1 into this correctly for the note-offs?
