I have a song I’m working on that has a midi piano part playing freely (no click) for the intro and then at bar 45 it locks to a tempo of 105. The song currently contains a freely recorded midi piano part, an additional midi guitar part, and recorded vocals over top. The midi piano part is straight 8ths, but its speeds up and slows down with the phrases, and now I would like to make a tempo map of the performance, but I cant seem to figure out how best to do it.
First off, I made sure that the project starts on the downbeat of bar 2 at a tempo of 105, which is good for the first few bars. Then, using the warp tool in the key editor for the piano part, I drag the beats to match the performance until bar 45, where it locks in with the 105 tempo.
However, the result when I playback is that the midi piano and audio vocals are in sync, yet my midi guitar tracks are COMPLETELY out of sync!! It seems the warp tool is mapping the performance for the midi piano part, but is actually changing how the midi guitar part plays back!!
Any idea what I’m doing wrong? I tried locking all the tracks before starting the tempo map as well, but this made it so the midi piano part was no longer in sync with the vocals. I’m at a loss on what to do!
edit: I think I might know what to do - lock all tracks EXCEPT the piano and then map. Going to try that now and will report back.
