Okay THIS is cool as hell: one of the features Apple added with the latest Logic Pro update is the ability to split an audio file into its constituent parts (vocals, drums, bass, and "other"), and the guy who did my bass guitar course actually wrote out a bunch of bass lines for a selection of 50 songs of various genres, and one of the ones included is Credence Clearwater Revival's "Bad Moon Rising". That song is actually in my iTunes library so I dropped it into Logic Pro, had it analyse the tempo so the metronome would match, then ran it through the splitter and muted the bass track. So now I'm actually playing my bass along for reals to the song! 🤘🏻
(The keen-eyed among you may note that the tempo according to Logic Pro is actually twice what it should be, I think the 8th-note hi-hats throw the calculations off but it doesn't really matter.)
