No /dev/sequencer, MIDI device in KDE Sound System and so forth

Hiya.
I'm having trouble getting MIDI to work properly. Software MIDI synthesizers (I think they're called that, anyway) like timidity work like a charm, but that simply won't cut it for some applications and I'd like to get the damned thing to work.
Some info first. I use Mandrake 10.1, kernel 2.6.8.1, I have a Muse XL sound card which gets detected as "CMI8738 - C-Media PCI CMI8738", which I assume is the chipset on the card. Typing "lsmod | grep midi" as root gives me this:

Code:

snd-seq-midi-event      6080  1 snd-seq-oss
snd-seq                47440  4 snd-seq-oss,snd-seq-midi-event
snd-rawmidi            19300  1 snd-mpu401-uart
snd-seq-device          6344  4 snd-seq-oss,snd-seq,snd-opl3-lib,snd-rawmidi
snd                    45988  14 snd-seq-oss,snd-seq,snd-pcm-oss,snd-mixer-oss,snd-cmipci,snd-pcm,snd-opl3-lib,snd-timer,snd-hwdep,snd-mpu401-uart,snd-rawmidi,snd-seq-device

I've looked into the KDE Sound System and I can't even choose a MIDI device. It's blank. Also, if I try playing a midi file with playmidi, it gives me an error saying

Code:

open /dev/sequencer: No such device

KMid gives me an error saying it can't subscribe to a MIDI port.

So, any ideas? Any help would be greatly appreciated.
Thanks in advance!

well? does /dev/sequencer exist? don't rely on KDE to tell you what's going on.

ls /dev/seq*

also do you have permission to this file? (this is what I expect the problem to be) if so,
then set permissions in accordance to the kernel model -- 2.4.x or 2.6.x.y

try accessing the device as root...does the problem still presist?

don't know how to do that, then change to single user mode as root init 3 then run X as root startx..make sure that
exec startkde is the only line in your .xinitrc file (note the period a the beginning of the file)

Hm. Curiously enough, I have two /dev/sequencers

Code:

[roguejedix@rogga-alpha roguejedix]$ ls -l /dev/seq*
crw-rw----  1 roguejedix audio 14, 1 Apr 27 11:29 /dev/sequencer
crw-rw----  1 roguejedix audio 14, 8 Apr 27 11:29 /dev/sequencer2

I think the other is for my onboard audio chip, but I've disabled that ages ago and I checked a minute ago just to be sure. Also, where exactly is this .xinitrc file? It's not in my home directory or in root's. Should I create one and paste in "exec startkde"?
