Hi, using the midifile functions of cm2 to import a file exported from the Muse Sequencer I ran into the following problems:
1. The time signature Meta event has length 2, which throws an error (bytes 3 and 4 are simply left out). 2. NoteOffs are coded as NoteOns with velocity 0. Rosegarden can deal with these things so I'm unsure whether Muse exports are valid or not (even if I couldn't find anything about 2 byte time signatures anywhere). As the changes are considerably small I wanted to let you know and would vote for being less strict about the time signature format and reinterpreting the NoteOn/Velocity 0 into NoteOff Messages (as this is common practice in communication between devices anyway). Below are the respective outputs of the MIDI Track Data (in Hex) of the same sequence in both forms to see the difference. Yours, Orm BTW: I also left a message on muse-devel (hope that doesn't start flames ;-) with NoteOff as NoteOn/Velocity0: ;dtime noteon pitch velo 00 90 1B 7F 83 00 1B 00 00 2B 7F 00 28 7F 83 00 2B 00 00 28 00 00 36 7F 00 34 7F 83 00 36 00 00 34 00 with NoteOff explicitely: ;dtime note-on/off pitch velo 00 90 1B 7F 83 00 80 1B 7F 00 90 2B 7F 00 28 7F 83 00 80 2B 7F 00 28 7F 00 90 36 7F 00 34 7F 83 00 80 36 7F 00 34 7F _______________________________________________ Cmdist mailing list [email protected] http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist
