[PlanetCCRMA] frustrated with midi - finding no help

[David Slimp]

Hmm...
perhaps THIS is getting somewhere....

$ ls -l /dev/snd/midi*
crw-------  1 david root 116, 8 Feb 10 16:10 /dev/snd/midiC0D0

$ ls -l /dev/seq*
ls: /dev/seq*: No such file or directory



Of course the output from the trace is huge...
if you need it all I could send it, but I think the
important part might be here:

stat64("/usr/share/alsa/alsa.conf", 0xbffff49c) = -1 ENOENT (No such
file or directory)
write(2, "ALSA lib seq.c:928:(snd_seq_open"..., 43ALSA lib
seq.c:928:(snd_seq_open_noupdate) ) = 43
write(2, "Unknown SEQ default", 19Unknown SEQ default)     = 19
write(2, "\n", 1
)                       = 1
write(2, "KMidiMon ALSA Error ", 20KMidiMon ALSA Error )    = 20
futex(0x413d43f4, FUTEX_WAKE, 2147483647) = 0
write(2, "Sequencer open", 14Sequencer open)          = 14
write(2, " rc: ", 5 rc: )                    = 5
write(2, "-2", 2-2)                       = 2
write(2, " (", 2 ()                       = 2
write(2, "No such file or directory", 25No such file or directory) = 25
write(2, ")", 1))                        = 1
write(2, "\n", 1
)                       = 1
write(2, "kmidimon: seq.c:1157: snd_seq_cl"..., 65kmidimon:
seq.c:1157: snd_seq_client_id: Assertion `seq' failed.
) = 65
rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0
tgkill(16906, 16906, SIGABRT)           = 0
--- SIGABRT (Aborted) @ 0 (0) ---
rt_sigaction(SIGALRM, {SIG_DFL}, {SIG_DFL}, 8) = 0
alarm(3)                                = 0
close(9)                                = 0



Does any of that help at all?

thanks,
David
