Hi,

Can't seem to find exactly what I am in need of.
 
I have a Sonar Plat project with audio (backing vocal tracks) that are in the project with MIDI tracks.
 
I simply want to increase the tempo of the entire project, but with the audio tracks in there, it doesn't seem to work.
 
The vocal audio tracks have be processed in Melodyne.

Any easy way to do this that I'm missing. Right now I'm using Sony Sound Forge to increase the speed of the wave file, but I'd rather not keep doing it that way.

Thanks.

Bounce to clips all audio to be single clips that start at Zero. With all audio clips selected, Enable Clip follows project in the Audio snap view. Change to the desired tempo. Verify audio is still in sync. Bounce to clips to offline process the stretch. (The realtime algorhythm won't sound as good, but will give you a nice preview)

Note that it's not necessary to bounce clips together (or the alternative: change the timebase of audio clips to Absolute) if the audio is already synced to the timeline, which it must be if it's playing in sync with the MIDI.
 
Also, when enabling Clip follows Project on the audio clips, make sure the mode set in the dropdown options for that function is 'Autostretch'.

I personally have run into issues with audio stretching tracks with multiple clips on single tracks and have found Clip follows project more reliable if Each tracks Clips are bounced to a single clip in each track starting at zero. (Not to be confused with bouncing the whole project to a clip... Not what I'm referring to) So while it's not necessary, I personally have found it to be more reliable. That's just my experience with it. I do a lot of time stretching and tempo manipulation. +1 on the 'Auto-stretch' setting. Best of luck to you. 👍

If the audio tracks are already in Melodyne, go to the Region FX menu and enable Follow Host Tempo.
