Here's a sample of things I've done, mostly for digital syntesizers.
The titled pieces link directly to MP3 files produced from the original MIDI sequences.
Feel free to download them, they should play on any sound card.
The link to the Chamber Music Archive takes you to a Music website I did for Project Gutenberg.
It features scores and parts for works from the classical chamber repertoire. They're in printable
and playable format called Finale. You'll need a (free !) reader from
Coda Music in order to use them.
