so I'm completely new to After Effects (normally work with premiere or stop motion animation) so if I've not given enough/or the right information, just let me know what you need to know.
I have a four frame animation, and want to use keyframes generated by audio to choose which frame to show of the animation (it's for a music video and each frame is a different position while playing an instrument). I was hoping to assign a frame to different value ranges generated by the audio, I've managed to animate other things with audio keyframes and linear expressions. The issue I seem to be having is that keyframes seem to only exist for effects, so I can't figure out how to assign each frame of the animation a value that I can then use in relation to the generated keyframes.
I'm sorry if that doesn't make any sense, but any help would be hugely appreciated!
