Fiddled with tempos and project is crazy

All of a sudden, my acid-wav loops started to take on a strange pitch and wouldn't sync up with the MIDI clips in the project.

Does Sonar recognize them as groove clips (Check the clip form, they have rounded corners)?

Yes, I had it happen again. I restored an old, old version of the project and changed the temp. Nothing synced up again. I don't think it's the MIDI that's going crazy because the acid loops sound kind of funny and it's like they're not lined up in the timeline properly anymore.

Thanks for the responses. Sorry for the additional thread. I panicked when it happened again to my project.

Differences in this project over the others is that I created grouped clips instead of individual ones and I had the VST z3ta+ in the project.

Best,

This may be a totally different issue but I had a project with nothing but straight audio tracks. (No loops of any kind, and no MIDI). When I recorded the song the temp was set at 100bpm, but I didn't use the metronome so the song is not synced to the grid at all. Later on I added a drum part with Reason rewired in, and when I got ready to lay down the drum part, I turned on the click in Reason which is automatically the same temp as Sonar, which was 100bmp. Obviously this didn't help because the song wasn't recorded to the metronome. So I tried to change the tempo in Sonar just so it would change the metronome click so I could maybe match it up with the song. But every time I changed it, it looked like it stretched the audio clips and even moved them a little. When I tried playing them, they seemed to be at the same tempo but they were not in sync with each other anymore. I was able to undo all of this and then just record the drums by ear, without the metronome, but I just wonder why changing the tempo would change the audio clips.

This doesn't usually come up because I usually record my songs with the metronome. I was just curious if this was a problem with Sonar, or just operator error. Anyone know?

I know this problem.

Groove clip your audio, but split the clips at hte tempo changes. If a groove clip extends past a tempo change it gets confused. Unlike HAL in 2001 though, it won't kill you, but it will no longer play in sync. A groove clip should stay in one tempo range, if the tempo changes, split the clip so it can sync to one specific tempo. Also, make sure the clips are NOT linked. Also a tempo-buster.

Let me know if that works, I tackled tempo issues thoroughly a while back....

Is there any difference between a "Groove Clip" and an "Acidized Wav"? I always assumed it was the same thing, and that "Groove Clip" was just Sonar nomenclature.

Sonar is lacking a "LOck to Time" functionality.

Any clip that does not start at Bar 1, Zero Time, will shift if you change MIDI tempo.
To demonstrate, Try a drastic change like 100bpm to 50bpm, and then 200bpm.

If this is the problem, the only WORKAROUND I am aware of is to bounce and/or slippedit all the audio, making all audio start at bar 1.
