[1st message:] Is MIDI a single well-defined standard or are there
multiple versions of MIDI?

 [2nd message, 30 minutes later:]  After sending the query about MIDI,
I did a search and found some excellent sites describing MIDI details
galore.  This site has excellent information and links on MIDI:

 [ Editors note:
 [
 [ Good going, Meta! In answer to 1st message:  The MIDI Association
 [ published and still maintains a single specification of "standard" MIDI
 [ functions which comprise the basic General MIDI capabilities of most
 [ sequencers.  Not all MIDI editing programs will preserve the standard
 [ functions during editing, however, and not all sequencers implement
 [ extensions to General MIDI in the same fashion.  Our member George
 [ Bogatko is arrangeing several instumental styles now with MIDI,
 [ including nickelodeon MIDI files!
