Hi, so I signed up to Puremix to develop my mixing skills,
and none of their mix templates are for Cakewalk.

What I want to know is, are there any converters into Cakewalk from
1) Pro Tools
2) Ableton Live
3) Logic Pro
4) Studio One 
5) FL Studio
6) Cubase

If it's not possible, oh well.
I thought it couldn't hurt to ask.
 

No.
If they’re just using audio tracks n which to practice your mixing skills that’s not the same as a template.

You can always see if there are any audio files and just copy them to Sonar.

There are many many sites where you can download audio files (stems) that you can import into any DAW to practice your mixing on.

Cambridge Music Technology is one particularly good one. www.cambridge-mt.com

Thanks for the reply. I intend to check out your site when I'm home. Sounds good!
