I'm a little confused. The .MGX file extension is for what? As far as I remember one could open band in a box files on either mac or PC without issue forever. In fact, when I moved my Band in a Box off of a PC to a Mac in 2007 or so (when there was finally a good version of Band in a Box for OS X), I simply put the 10k+ files I had from PC on to a flash drive, and then put those on my Mac and they work perfectly.

So, not sure exactly what a MGX file is (I don't think the Mac version creates them...or I've never seen my system create them).

As for MIDI and KAR files......that really is not what Band in a Box is supposed to be. It's NOT a midi sequencer. There are PLENTY OF CHEAP OR FREE ones for Windows or Mac. Say, PowerTracks for instance? Or Logic?
