hahaha. yeah kind of. like an Envelope Follower. lets says you laid down some neuro whip turn around basses let's say A to F# if you have a device that detects pitch and has a map or side chain capability, you could have it automate the dry wet of a flange, saturator, reverb, etc. BUT it would only kick on when the Amaj plays. what made me think of this was vocal sampling. I was thinking how I could get a more natural sound when going from note to note in a sampler. I came to the conclusion that there's more harmonics on some notes than other when you sing naturally. A little more raspy. then I figured I would add a distortion for harmonics and wow filter on others to change the "vowel" slightly. that way it wouldnt sound so robotic and unnatural. then I thought if I could do it with an envelope follower and the answer is no because I'm not automating the amplitude, I'm automating the pitch. I now some notes are naturally "louder" than others, so It would work some what if I dont compress before hand. I feel like it could be done with midi fx stuff in ableton. but I don't really use midi fx stuff so I don't know. I'll have to get on some knowledge about that.
