I still don't quite understand. It's true that the editor won't allow you to put eight quarter-notes in a single bar without a time signature, as illustrated in that image. But that doesn't seem to be quite what you're describing, as you'd obviously get four notes, not two, before having to go to the next bar. The keys and accidentals are the interesting thing here, and presumably the point of the image. All of the accidentals shown simply duplicate those in the keys, so presumably this is an illustrative example only -- i.e. with the key signatures shown, the pitches shown would normally have no accidentals, but they've shown the accidentals explicitly just for the purposes of the exposition. You can't yet do this in Rosegarden (i.e. tell it to show explicitly all the accidentals that notes inherit from a key signature). Also, of course, Rosegarden supports neither the quarter-tone notation nor quarter-tone pitches themselves (nor any other alternative tuning). There are a lot of requirements associated with entering and playing (correctly) non-traditional-Western notations, and while these are all desirable post-1.0 features, they mostly will not be in 1.0. > [...] What MIDI codes they have? A quarter-tone falls between two MIDI pitches -- MIDI pitch is an integral number of semitones. To play them with a normal MIDI instrument requires a pitch-bend controller event. Chris
