I did a quick search on the forum as well as the internet, of course and probably not the whole thing, but I got a question and need your expertise:
I'm able to set the layer, clip and composition opacity to "external audio", right? (under transform) - If I'd like to switch between "external audio on" and "please just keep it at 100%" I'd, if it was an effect, just map a key of the midi controller to the "bypass button" or smth. - The transform thingy is missing such a feature (and of course the bypass means "completely off", instead setting it to a specific parameter).
Is there any way to switch between audio reactive opacity and "100%" opacity with just a tip of a button? I'm sorry if it's not quite clear what I mean, really little sleep.

Thanks a lot in advance
PS: If I'm just missing a effect that could do this feel free to slap me with what ever you want.
