Support additional types audio tweens?

[johanhelsing]

Maybe I'm mistaken, but as far as I understand, it looks like kira supports lots of different tweens (allowing frequency slides etc.), but that the only exposed tween is through the fade_in command.

Or maybe exposing such features is out of scope?

I wouldn't say it's out of scope, but probably quite low priority compared to features like audio streams and clocks.
