I'm sure this has been suggested and so probably a good reason it doesn't happen.

But when we buy a license and extra RealTracks, why can't they be for both operating systems? Are there many people who have gone out and bought a license for both Windows and also a license for the MAC anyway? I mean what would PGMusic lose on this?

It just seems while there are features missing in the MAC version and RealBand of course, it would be nice to pay the same as a windows user and still feel that there's an alternative to use in Parallels, if you have to slip over to finish something off or try something out in a feature that is just not available in the MAC version. For me in would probably be RealBand for example.

Just sayin'
