Hello and Merry Christmas to everyone
 
I wanted to try do a remix of a Tears For Fears song http://play.beatport.com/contests/tears-for-fears-pale-shelter/
I have downloaded the audiofiles (WAV) and imported them into Sonar X3d Producer. So far so good.
 
Now some questions 
1. There is no provided info about tempo or key. How to get these in Sonar X3? (it states 119 bpm on another site..)
2. If I set tempo to 119 bpm. the tempo seem to run correctly for about 4 bars, then it is out of sync. Do I need to quantize the audiofiles? 
3. In Audiosnap I tried to use the "clip follows" project and Quantize functions. The timing still seem off....
Is the audiofiles out of sync from the beginning??
 
I want to introduce another kickdrum in the track in addition to a new synthline etc. tempo is important as you understand.
It would really do my day if someone could help me out with the above. Hopefully someone actually doing the remix themselves;)
 
Thanx:)

Drag the file into Ableton. Make sure the warp type is set to "complex" (I think "beats" is default). You're done.

I know that's kind of a lame answer in a Sonar forum but Ableton is brilliant at this and Sonar kinda sucks at it. Different tools for different jobs. The simplest version of Ableton will do, and even a demo will work. If you prefer working in Sonar, export the audio and load it into Sonar. You can switch between Ableton's clip view and arrangement view by pressing TAB.

EDIT:
I got Ableton Live 8 Lite. Don't use it much but I have install it again:)
 
EDIT - don't seem to have all function in Warp mode...
 
PS - still seem so complicated to work with Sonar for these kind of projects. Even though I love Sonar X3
Thanks.

Review this for guidance:

In the above, look for the link to: "To sync the project tempo to an audio clip"

Melodyne is a good option for this sort of thing.  You need to open in standalone mode to convert your files to a standard consistent bpm

I read the article and I am aware of most of it. Will try it out though
Dubdisciple... I know that Melodyne is great for a lot of stuff. Just have essential version so see how it work out.
 
Perhaps anyone would be so nice to download the stems and check them out?;) Its the first time to apply time stretching techniques from a whole song. Much easier with smaller chunks of loops..

Thanks again guys:)

The version included with Sonar will be just fine since they provide individual tracks. I tend to chop up parts anyway, regardless of what software I am using.  a lot more manageable

i may download stems later
 

Looks like you've now got a lot more competition! :)

Hm, sounds interesting.  Had a similar issue on a remix of a piece of classical music 
 
IMHO, although you can have the tempo of the project follow the stems, it really doesn't seem to help.  The major problem is if you drop in loops, the loops will not still be right (or not sound correct).
 
So, I believe it's better to quantize the whole thing to a locked-on 4/4 beat.
 
What I usually do is take the whole mix, determine an approximate tempo (by using Tap Tempo), then turn audiosnap on and have it do a first attempt at transient detection.  I then remove all the ones that are not on the 1st beat of a measure.  If it's missing them, then I add them manually.  You may not have to do that for the whole song, but if timing drifts much, you will probably want to do that.
 
Then I manually move the transients so they lock on first beat of a measure.   If you have the other stems loaded, their transients can be moved as well.  I then turn on the metronome and see if everything seems to be locked up.  You will also want to use Radius Mix for offline processing and freeze the track every now and then to check the quality. You also might have to try another offline processing algorithm if it seems to sound better. 
 
It's a bit time consuming, but what I've found is that most remixes will use only a few parts and even those parts get repeated.
 
I'd try it now, but I'm visiting my folks for the holidays, and a long way away from my DAW. :-)
 
It is true this is much easier in Ableton.  It's one feature that I would like to see improved in Sonar, along with easier chopping and sampling.  This would make Sonar more idea for remixing.
