I don't know about online sources or communicating via MIDI, but I could mail you the sheet music if you like. Email me your street address if you need me to do so.

An interesting thing about Kalenda Maya is that it works very well both in 3/4 time and in 2/4. We used to do it slow and dreamy in 3/4 and then jump into a quick and rhythmic 2/4.
