Note the difference in spelling: Turkish makam and Arabic maqam. And Persian 
dastgah. The site [2] above is of the Arabic maqam. I made a file for that in 
E53 with two commas for the microtones, using Graham Breed regular.ly, and 
Helmholtz-Ellis accidentals, cf. [3]. The Arabic maqam simply use a different 
set of accidental glyphs, two missing in the traditional system, the ones with 
arrows at [2].

It would be good if you listen to the microtonal pitches of the MIDI at [3], 
telling if they sound fine.
