*Bug 566665* <show_bug.cgi?id=566665> - [abrt] instability from snd-mtpav on
PCI parallel port, causes crash in jack-audio-connection-kit-0.118.0-1.fc12
(edit <#>)
The issue is one of either no midi input, or once I start hooking up a
device that sends midi clock, start/stop, etc, i get spurious midi input.
Although the effect is interesting (wavering pitches & pressures all over
the place playing back midi files), it is also nondeterministic.
Before triggering the bug (which I can only reset by reboot), the device
does work fine for 8 channels of midi output....
It's terrible to have hardware this useful so close to working....
Is this a bug in module 'snd-mtpav' ??

Or am I doing something wrong. One person told me, online, I should stop
using '-X seq' in jack, and use http://home.gna.org/a2jmidid/
Is that spurious advice??
