moonboy Posted June 20, 2020 Share Posted June 20, 2020 A strange thing... When I change the key signature in the list editors, it warps the audio pitch of the lead vocal. Eg. changing key from C maj to A maj (so I can use the score display for a midi keyboard part) pitches down the vocal audio by 3 semitones. But NOT any other audio in the project! The vocal track has not got flex enabled. It appears to affect the vocal whether or not the channel is selected when I change signature. I'm pretty sure that changing key signature is only supposed to affect display of midi notes only? I set up a new blank project to try and replicate the effect but I can't - so far it's only happening in one project I'm working on - any ideas what's causing it?

triplets Posted June 20, 2020 Share Posted June 20, 2020 Probably project corruption. Create a blank project and import the tracks thru the Project Browser window, and continue working there. Quote Link to comment Share on other sites More sharing options...
moonboy Posted June 20, 2020 Author Share Posted June 20, 2020 Yes I thought it might be corruption, but not encountered it before. A fresh project sounds like a good idea, thanks for the reply. Interestingly - the vocal pitch shift is pretty successful, much less glitchy than flextime and much less laborious than the time and pitch machine... whatever the corruption is has created quite a powerful tool, if it were to be controllable!

David Nahmani Posted June 21, 2020 Share Posted June 21, 2020 I doubt it's corruption. Can you post a screenshot of the region inspector when that audio region (or one of the audio regions that is transposed) on the track is selected?

moonboy Posted June 21, 2020 Author Share Posted June 21, 2020 Hi, here it is. No change I can see in the inspector when it transposes. After the key is changed the audio plays back fine on first play, but if you hit play a second time from the start of the region, it's transposed. I'll do a screen recording to demonstrate...

Solution David Nahmani Posted June 22, 2020 Solution Share Posted June 22, 2020 Hi, here it is. No change I can see in the inspector when it transposes. Notice that "Follow Tempo" is on. That's the culprit. That means that you have Flex turned on for that track. Turn that off and the audio won't be transposed. Quote Link to comment Share on other sites More sharing options...
moonboy Posted June 22, 2020 Author Share Posted June 22, 2020 Thanks David, yes that fixed it! I didn't think to try that as I haven't changed the tempo! I had no idea that the key signature would affect audio through a function related to tempo - I haven't seen a mention of this before - only that changing the key sig affects apple loops and midi display. So 'follow tempo' basically treats the audio region as a kind of apple loop then? Also I've read that 'follow tempo' only appears in the inspector for regions recorded in that current project, however in my current project 'follow tempo' appears in all the vocal tracks which were imported from my collaborator's Garageband project, and most of the audio regions I've recorded straight into the logic project don't have 'follow tempo' in the inspector (but do have 'flex'). I'm a bit confused about when this feature is supposed to show up now! Quote Link to comment Share on other sites More sharing options...
