I have several MIDI files on my computer. They ALL play fine on 10.10 or earlier, but in 11.04 Natty maybe only about 50% of them play. Totem will recognize all the files in Natty and even show track time and show the song playing, but no audio. Anyone care to venture why some MIDI files work and some dont in Natty? The same files work fine on 10.10 and a 10.04 system.
