Need help getting MIDI sound to work (Ubuntu Edgy)
 

I posted this in the Ubuntu forum, but no response to date. Maybe someone here can help me?
-----
When I run Timidity or Kmidi, I get a message indicating I don't have a "Sequencer" device. I don't have a clue how to install one.

Here is what I get from Timidity:
bryan@ubuntuPentium:~$ timidity -iA -B2,8 -Os &
[1] 6111
bryan@ubuntuPentium:~$ Requested buffer size 2048, fragment size 1024
ALSA pcm 'default' set buffer size 7524, period size 3760 bytes
TiMidity starting in ALSA server mode
ALSA lib seq_hw.c:457snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
error in snd_seq_open

With Kmidi I get an error message:
"Could not open /dev/sequencer.
Probably there is another program using it."

Any takers on this one?

Thanks, Bryan

PS - My (Ubuntu) Edgy install is on a P4. The sound system works fine - playing CD's, MP3's, sounds in browsers, etc. Just MIDI seems to be problematic. Also, MIDI works just fine under XP.

Sounds like you need to see if a) you have a module available for your midi onboard device, and b) if there is, make sure the module is loaded, and if it isn't loaded or compiled, you need to load or compile it.
As you are using alsa, you could use (in a console) the command ALSAMIXER, and see if there is a control(s) on the mixer panel for the midi channel/device, make sure it is activated there.
If you change anything in the mixer, then after you exit, you must use ALSACTL STORE to save the settings.
typing LSMOD in a terminal will tell you what modules you have loaded.
If you don't see one like "alsa_snd_seq" or something like that, then the sequencer is not loaded.
I am not too familiar with Ubuntu-Edgy, but on my system (Slackware) I have a modules-2.6.20 file in my /etc directory, which can be used to load or 'modplug' kernel modules during boot. If such a file exists on your system (in the /etc folder) search it for the needed sequencer module for your device, and uncomment the device line so it will load during boot.
Ubuntu may not have such files, so you will need to skip this step.
If there is a module compiled but not loaded, try typing MODPROBE ALSA_SND_SEQ (for 2.6 kernel) or INSMOD ALSA_SND_SEQ (2.4 kernels) and see if it will load.
As a last resort, I would venture a guess that you may need to enable support for the necessary midi device in the kernel, because it isn't there yet, in which case you would have to custom-config a kernel with the needed support.
It isn't as bad as it sounds, but if this gets you anywhere for starters, please post your findings and someone wll try to help further.
