There are a large number (perhaps 100)of 'pop' MIDIs at iranianmidi.com and a music discussion group at iranmidi.com which I have just joined. The MIDIs I've looked at to date have been input via a piano keyboard and are fairly fickle when converted to sheet music - particularly when it comes to note duration. I'll need some more experience before I can indiscriminately quantize the note lengths without risk of killing the soul of the music.

Still no luck with any traditional music just yet. I have no idea whether trad/classical Persian music can be effectively translated to MIDI, which I surmise was developed for Western musical genres.

The local State Library is a phenomenal resource for Western music - I'll be there tomorrow to check how good their Eastern collection is.
