I am currently working with Sonar X and I own LE and I know that LE can be installed in Mac. But can Sonar X? Also, is Ubuntu in the page or not?

Sonar LE can be installed in Mac??
As far as I know, the only way to run Sonar on a Mac is by installing Windows on it first.

No version of Sonar will run on a Mac unless you use another program in which he you can run Windows first.

Nor will it run on a Linux OS. You may get it to work via Wine but not very well.

Actually, now that you say it, I'm not a 100% sure if the Mac user (not me) was using a virtual machine or not.
P.S. I am a Windows user and I have Roland Duo-Capture EX (that sound card I'm absolutely positive it works on Mac :D) and I got Linux installed on another HDD. I was wondering if I could install Sonar as well.
Another question: Is there drivers for my sound card on Linux?
@ sanderxpander & @ mudgel: Thanks a lot for the reply

Never mind. Just found it!!
 

You may try a program (in a Mac) called 'Bootcamp'   it runs as windows XP (or it may have an updated windows version by now)

Nope never unless you can run windows (or perhaps wine).

Please go to your Linux distribution forums.

Bootcamp doesn't include Windows, it'll just let you install regular Windows. Any version should work.
