I’ve noticed what seems to be a bug with transition timelines in FMOD Studio 2.02.29. If I create a transition timeline and don’t add a fade in to the destination there is still an audible fade in. This means I can’t fade out the source while having the destination come in immediately.

I’m afraid I haven’t been able to reproduce this issue. When I test here, if there is no fade-in curve on the destination region, I am unable to hear any fade-in when auditioning the event.

I must therefore be doing something differently to you. Are you able to upload a project that exhibits this issue to the [uploads tab of your profile page](https://www.fmod.com/profile#uploads)?
