But "seq24 --showmidi" also shows the duplicated noteoffs: atte@aarhus:~$ seq24 --showmidi Reading [/home/atte/.seq24rc] [JACK sync disabled] [000000] [FFFFFFFE] 00 00 00 [000000] [0003] 90 48 42 [000000] [0003] 80 48 00 [000000] [0003] 80 48 00 [000000] [0003] 90 3D 4C [000000] [0003] 80 3D 00 [000000] [0003] 80 3D 00 I checked with my three evolution usb-keuboards and both mk-249c2's send the extra note off, whereas the (newer) mk-449c works like it's supposed to. So it looks like a bug in the eveolutions. I remember playing a bit with muse when I bought the first mk-249c2 two years ago. At that time muse also showed the duplicate noteoff, where as I don't think rosegarden did. Anyways, just recorded a note in both rosegarden and muse and at least they don't show the extra noteoff. So it seems that rosegarden and muse have a workaround for that kind of behaviour... I can't tell whether it being recorded or not, but here's the files recorded in muse/rosegarden, maybe someone else is able to tell if the duplicate noteoff is in the files at all or not: http://www.atte.dk/download/2noteoff.tgz -- peace, love & harmony Atte http://www.atte.dk
