I'm trying to find technical details about my DCA1 Mark III -- stuff 
like whattypes of content I can put on the CD/floppies/how do I 
create the content, the format differences between the various 
content types (e.g. PianoSoft.*, CueTime, Virtuoso Performance, 
etc.), how I can programmatically interact with it from my PC/MAC, 
etc. Also, are all the manuals online somewhere?

TIA,
Dirk
