[added: 96] Multi-frequency opacity

Hi all,
I've been away from this community for a while, so forgive me if this has already been discussed/implemented (though I couldn't see it in the docs).
I'd really like a way to set a layer's opacity based on the bass/mid/treble (or more granular if possible I guess) currently playing, rather than just a slider. I know I can do a slider, but opacity would allow for some neat effects too.
