I recorded several tracks into a song from ADAT with the wrong tempo so now I need to change it. However, every option I tried for altering the tempo seems to throw the audio tracks off. Is there a way to just simply change the tempo of the song without screwing up the synchronization of all my tracks?
Your probable best bet is to re-record the tracks at the right tempo. Otherwise, you’re probably destined for a Cubase timestretch process or another app that will automatically timestretch with the tempo adjustment. I use Melodyne Editor for this process and it works quite well as long as the tempo change isn’t too extreme. Of course, that will be the case with any app.
2 things to do…
- In the Audio Pool, make sure that “Musical Mode” is unchecked for each audio file.
- In the Project window, switch all audio tracks from Musical Timebase to Linear Timebase (change each track’s “quarter-note” icon into a “clock” icon).
You can now change Cubase’s tempo without affecting the audio.
It’s worth trying musical mode but prepare to be highly disappointed!
Re-recording it would most likely be your best option here.
Linear Timebase worked perfectly!! Thanks for the replies everyone…
Excellent tips. In my case, by ‘changing tempo without altering audio,’ I wanted Cubase to actually change it so as to keep everything lined up and sounding exactly the same, except faster (I recorded a song with vocals but wanted to increase the bpm). Sort of the inverse of what vic_france is offering. So to do this instead:
- In the Audio Pool, make sure Musical Mode is turned on.
- leave all audio tracks in Musical Timebase, and
- change the song’s Tempo in the transport as usual.
This keeps all audio events in their place and stretches/compresses them to sound right. My change was only a few bpm (85 to 87 bpm) so it works, but yes, I would recommend re-recording to prevent artifacting, especially with dramatic changes (>5 bpm).
What about all the midi? Was this covered?
If you have previously quantized midi, it will all be on a grid and will move to your tempo changes accordingly. If your midi is in free form, (not played along with a tempo time clock) that may be a problem.
