Issues with looping time-stretched music in Unity

Thank you for the extra info!

I was able to reproduce the issue on my side when changing the parameter during runtime, so I will forward this to the dev team for further investigation.

In the meantime, another possible workaround you could try is using an Autopitch Modulator.

Here’s a quick setup to test:

  1. Create a new event and add only the livesLeft parameter sheet
  2. Drag your asset onto the audio track, click the single instrument and enable Loop Instrument
  3. Right click on the pitch knob, select Add Modulation > Autopitch
  4. Set the root pitch to 3 and tweak the min pitch to match your design

Hope this helps! Let me know if this works for your project.
