 |
|
Hi everyone,
I'm trying to get MIDI working with my SB Live! and an external synth, connected to the MIDI ports of my Live! Drive. I'm using ALSA 0.9 and the ALSA driver for my Soundblaster.
When I do the following -
| Code: | cat bwv863.mid > /dev/sound/midi00
|
the midi comes flying out of my synth as fast as it can be piped. (The midi is the G# Prelude and Fugue from Bach's WTC I, for anyone who cares  .) Therefore I know that at least the /dev/sound/midi00 device is working.
Here's what my /dev/snd and /dev/sound directories look like -
| Code: | $ ls -l /dev/sound
total 0
crw-rw---- 1 root audio 14, 12 Dec 31 1969 adsp
crw-rw---- 1 root audio 14, 4 Dec 31 1969 audio

$ls -l /dev/sequencer
lr-xr-xr-x 1 root root 17 Feb 24 14:45 /dev/sequencer -> /dev/sound/midi00

First of all, what's the difference between /dev/snd and /dev/sound ? Is one ALSA and the other OSS? The symlink between /dev/snd/seq and /dev/sound/midi00 I made myself, and I think I also made the one from /dev/sequencer to /dev/sound/midi00, but I'm not positive.
What doesn't work are commands like the following -
(pmidi -l lists possible output "ports")
| Code: | $ pmidi -l
Could not open sequencer Inappropriate ioctl for device
$ kmid bwv863.mid

Anyone have any ideas?

You shouldn't have made those symlinks, I believe.
/dev/snd is the ALSA system, and /dev/sound is the OSS system. I take it you're only interested in ALSA, so let's stick to that.
Here's my /dev/snd: | Code: | ls -l /dev/snd

C0 is my internal Intel8x0 sound card that has no MIDI or synth capability. C1 is the serial MIDI port (snd-serial-u16550), and C2 is snd-virmidi - a kind of patch bay.
Get rid of your seq symlink. A sequencer is not the same as a raw MIDI port. The sequencer handles timing, whereas a raw MIDI port just sends raw data to the device as soon as it gets it. I also don't have a /dev/sequencer, and I don't need one for pmidi to work.
Perhaps deleting the symlinks will solve your problems. It might be that pmidi is trying to use one of them since it is there, and finding that it does not connect to the type of device it expects to see. |

In short, I noticed that the alsasound init script was not modprobing my synth device. I modprobed it myself, and it works fine. I don't know what alsasound wasn't trying to modprobe my MIDI, but this workaround will do for now:
| Code: | | # modprobe snd-emu10k1-synth |
