 |
|
hi!
just got my Midi to work and wanted to share what i found out in a few hours 
you maybe need this line in your /etc/modules.d/alsa:
alias /dev/snd/seq snd-seq-midi
(haven't tested without so far but it's definitely not bad )
1) find a soundfont (*.sf2)
for me it was CT8MGM.SF2
(from the driver CD or <add stupid drive letter here>:\Programme\Creative\SBAudigy\SFBank)
2)
3)
4) unmute your 'Music' with alsamixer, gnome-alsamixer or whatever you prefer
5) (for testing)
6)
to get a list of midi 'devices'
example:
| Code: |
Port Client name Port name
64:0 Rawmidi 0 - Audigy MPU-401 (UA Audigy MPU-401 (UART)
64:32 Rawmidi 0 - Audigy MPU-401 (UA Audigy MPU-401 #2
65:0 Emu10k1 WaveTable Emu10k1 Port 0
65:1 Emu10k1 WaveTable Emu10k1 Port 1
65:2 Emu10k1 WaveTable Emu10k1 Port 2
65:3 Emu10k1 WaveTable Emu10k1 Port 3
|
7) | Code: | | pmidi -p 65:0 /path/to/some/midi/file.mid |
 listen to musik happily
hope it helps someone else too
regards |

you can check if the soundfont is loaded with
| Code: | | cat /proc/asound/Audigy/wavetableD1 |
example:
| Code: |
Device: Emu10k1
Ports: 4
Addresses: 65:0 65:1 65:2 65:3
Use Counter: 0
Max Voices: 64
Allocated Voices: 0
Memory Size: 134217728
Memory Available: 126721308
Allocated Blocks: 528
SoundFonts: 1
Instruments: 1849
Samples: 526
Locked Instruments: 1849
Locked Samples: 526

I see at least to ways to do that:
- add your "sfxload your_sound_font > /dev/null" line to /etc/conf.d/local.start
- create an executable shell script /etc/alsa.d/emu10k1
| Code: | #!/bin/sh
sfxload your_sound_font > /dev/null |
The 2nd tip only works if you use the "alsasound" init script, but it is cleaner because it will only be executed if alsasound is started and has loaded emu10k1 modules. |

i have no /etc/alsa.d directory, but i am using /etc/init.d/alsasound to start up alsa, and it is in the default boot level
should i create /etc/alsa.d?
thanks.

| Yes, you can create it safelly. You're right that the directory does not exist by default, it's normal. |

here's what i did:
| Code: | mkdir /etc/alsa.d/
echo "sfxload /home/carrett/sf2/4GMGSMT.SF2 > /dev/null" >> /etc/alsa.d/emu10k1
chmod +x /etc/alsa.d/emu10k1
|
it didn't work though...the sound font is in /home/carrett/sf2/4GMGSMT.SF2.
what did i mess up?
EDIT: if i run /etc/alsa.d/emu10k1 after the boot sequence is done, it DOES work...

| It seems that you've forget the first line: #!/bin/sh |

fixed that, but it still doesn't work.
i can run the script after the bootup sequence with no troubles...this is weird.

I don't really understand where does the problem comes from.
Verify that alsasound is in runlevel "boot", and not "default".
Then check the output of alsasound on bootup? I've got:
| Code: | * Initialising ALSA.... [ ok ]
* Starting sound driver: snd-emu10k1 |
Is that the same for you?
Then put something to check if the emu10k1 scripts gets executed:
| Code: | #!/bin/sh
echo "/etc/alsa.d/emu10k1 does work." |
And if it is executed, add the sfxload command without /dev/unll redirection to see if there are any message.
It could also come from devfs not creating sound devices. Do you use devfs? If yes, maybe you need a few fake access to the devices to create them. In my emu10k1 script, I have a "ls /dev/mixer" to force mixer device creation. Maybe you need to do this on "/dev/sequencer", or "/dev/sound/sequencer" (I don't really know, devfs is black magic for me).
Good luck. |

it must've been a devfsd problem because i was getting /dev/sequencer no such file or directory errors
anyway, i tried both ls /dev/sequencer and ls /dev/sound sequencer and neither worked.
what DID work was something that i guess sparked up the midi, i ran pmidi -l in the script and that created /dev/sound/sequencer (/dev/sequencer for me is just a link to /dev/sound/sequencer)
so...thanks guys it works now.
