Another user has somewhat recently reported a similar issue to you i.e. tracks with volume automation/modulation applied to them desynchronize when subject to virtualization - does this sound like the same behaviour you’re experiencing? [Mixing different loops/tracks to "compose" a soundtrack at runtime in a Unity game](https://qa.fmod.com/t/mixing-different-loops-tracks-to-compose-a-soundtrack-at-runtime-in-a-unity-game/21065) A desync when virtualization occurs shouldn’t be happening. Could I get you to upload your FMOD Studio project (or a stripped down version where you can still reproduce the issues) to your [FMOD user profile](https://www.fmod.com/profile#uploads) so that I can take a closer look? Note that you’ll have to register a project with us to do so. --- _[View the full topic](https://qa.fmod.com/t/audio-clip-length-and-performance/21308)._
