Thanks for the help Michael…
I did as you said, and added the new keyframes and deleted the original ones. But I seem to be having the same problem, if I speed up or slow down a portion of the clip it distorts the rest of the clip as well.
I was expecting that if I slowed down a portion of the clip the overall clip would “stretch” along the timeline to compensate, but instead the clip length stays the same and the everything after my remap is just squished together to sound something like the Chipmunks Greatest Hits.
