midi drums - a note specialized for sound, not melody
Remember that midi channel #10 on each device is reserved for drums. MIDI assigns each drum a certain note number. For example, when you send a note of octave=2/note=C on channel 10, the sound module will hit an "Electric Kick Drum".
Here's some of the notes mapped to Drums on channel 10 (and the wierd little 4 char codes PianoCheetah uses for em)

Some sound modules will let you send a program change on channel 10 to pick different "drum sets".
Some sound modules don't need a note off event for drums since they're percussive and don't have a true duration (unless muted early, etc.) Some do need the note off.
The exact drum sound used will likely be different between sound modules... Such is the way of midi... It's tough to standardize sounds... :(
We'll get into that later in the sound section.
