I've got rawmidi working, and it doesn't seem to have a problem with the master volume slider. So I guess it is an alsa-seq issue. If I move the slider I get this in rawmidi (4 lines for each increment): read f0 read 01 read 7f read 7e read f0 read 01 read 7f read 7d Are they valid MIDI messages? Damon
