Hi! I assume you’re talking about crossfading between several mixes which should stay strictly synchronous, by the use of a continuous parameter automation, with seek speed enabled. What you describe is indeed a missing functionality of FMOD: the possibility to add a seek speed on volume (and other attributes). That way, you’ll be able to use a discrete parameter, or continuous without seek speed on it (it will react instantly, going for instance from 4 to 2, as you want), but the cross fade would still be possible by that volume seek speed. **The more we tell FMOD staff this feature would be great (which I really think), the more are the chances they implement it soon 😉** However there’s some (a bit cumbersome) workarounds. You can read the answer I gave on [that thread](https://qa.fmod.com/t/how-do-i-crossfade-every-variation-of-my-our-games-overworld-music-into-each-other/16985), it may give you some leads. --- _[View the full topic](https://qa.fmod.com/t/need-help-on-evolutive-music/17094)._
