In any version of Sonar Xx I can remember, the draw tool doesn't snap correctly in a project from the point of the first tempo change until the end.  I'm assuming the tool just continues to draw at the previous tempo.  This is kind of a deal breaker for scoring work or any other complex music with tempo changes that relies on metric automation for effects/etc.
 
I reported it as a problem through Sonar's bug reporter but it apparently didn't make it into this new update so maybe if enough people can confirm it, we can get it fixed?

Correct, this is how it behaves, not a very nice bug really.
 
I'll go make a report too, things need to be reported to get attention !.

Well I'm fairly clueless to be honest but this is what I did, it's taken a while to work this out (really need to baby spoon me here):


1. New Project
2. Insert audio track
3. Arm and Record audio track (say 10 bars worth).
4. Insert a new tempo (let's just say 145) at bar 5
------- so far we have a project that is 120bpm through bar 5 where it then switches to 145bpm --------
5. Bring up automation for panning, volume or anything else
6. Set the draw tool to saw wave.
7) Set event draw duration to 1/4
8) Set snap to whole note.
9) Draw across the automation from bar 1 through bar 8 onwards....

I get the below image, note the leadup is a straight line, however I drew it from bar one and the line got created.... No idea....
 
Anyway here is the image, does this prove anything...?
 


What is missing from these steps otherwise?

 
Hey Alex, if you record audio, yes it does ... from bar 5 it's way off the mark :-)

Ok could you post the issue number here please... Thanks..

Hey Alex,

The problem hasn't been resolved as of X3e.  Here is the issue number: CWBRN-19135
 
Still works exactly the same way.  If you go up to the image you posted when you replicated the issue, you can see how your saw wave snaps correctly (every whole note), and then once you move past the tempo change, the snap drifts to some random interval (or maybe continues at the whole note value of the previous tempo).  If you tried the same steps again in X3e, you could replicate the same problem.  I hope it's fixed in the next update!
 
Thanks for following up!

that's a peeve of mine as well...
 
cubase handles it about the same as sonar.  studio one and reason edit perfectly with tempo changes.  i have noticed on occasion in studio one that drawing right to left from a faster tempo to a slower tempo can cause some anomalies.
 
the other thing in sonar that catches me off guard sometimes is that if you choose square wave and draw automation from left to right or right to left, then reverse which way you're drawing it changes from square wave to triangle wave...

Thanks for confirming.
