This is a reply to the guy having trouble sending MIDI files to PC's from 
Mac's.  I didn't reply to this one originally because I thought someone 
else would tackle it, which is why this response isn't  in-thread.  Anyway, 
I believe those .BIN files are binhexed (might just be another proprietary 
Mac format, too; dunno).  In any event, if you want to communicate with 
non-Mac machines, you have to use a common format, not a proprietary one. 
 The equivalent in PC terms, to turn it around, would be if a PC user sent 
you a Zipped file; you wouldn't be able to read it on the Mac.  Likewise, 
you couldn't view a Tarred UNIX file.  However, there is a standard MIDI 
file format, and your software probably creates it; check the output 
options of your software.  On the PC such files have extensions of .MID; I 
don't know what they'd be called on the Mac, but probably something real 
similar.  Hope this helps.
