If I move the slider I get this in rawmidi (4 lines for each increment):

Are they valid MIDI messages?
No. These look like the first four bytes of master volume sysex messages, but anything after the first four bytes seems to be missing. Sysex messages end with a F7 byte, so it's possible that the following data gets misinterpreted.
Please show the output of "amidi --dump" with some key presses after you've used the master volume slider.
Here's a few key presses, then some master volume slider movement, then another few keypresses:

(By the way another UF5 user has noticed the same problem, so it isn't just my system. And I'm using Fedora 6, which has alsa-lib-1.0.12-2.fc6)
