Fellow MMD'ers:  I've been begun collecting MIDI piano files on the
web.  I'm just starting my search and have not dug deeply, but in
response to recent questions about MIDI piano music sites I thought
I'd throw in my two cents.  Here are a few recommendations:

Ragtime and Stride:

Warren Trachtman's recent posting about the on-line data base sounds
great [000612 MMD].   Until it's up to speed there's Sue Keller's
Ragtime Press homepage which now carries the huge MIDI file catalog
that once graced the Ragtimer's Home Page: http://rtpress.com/

While there are many interesting MIDI ragtime & stride sites, one
of the best is the late John Roache's site:

In addition, master piano roll arranger John Farrell has discovered
MIDI.  Check out his work at
http://homepages.tesco.net/~stridepiano/midifiles.htm.

For general MIDI piano music sites try the following lists:

The Piano Tuners Guild MIDI page http://www.ptg.org/

Also for Ragtime and popular music:

  http://www.geocities.com/BourbonStreet/2422/

Some of the music on these sites is simply wonderful.  Others, quite
frankly, stink.  The fun (for me) of searching on the net is finding
a gem or a surprise, like 16 year old Martin Spitznagel's ragtime page.
I hope to post my own MIDI files one of these days.  (Hopefully they
won't stink.)

Happy hunting.
