have a look at the gentoo forum about the virmidi stuff. It does not
realy help but share the problem...
For those who seem to be interested in UBUNTU/DEMUDI,
here are some steps that I resolved and some others where
I'm new in Linux/audio.
For a first time with I would like to record my bass with
rosegarden and play drums with hydrogen.
My card : maudio 1010 LT which don't have Synth Support under ALSA
Synth devices : NOT ENABLED IN CONFIG
> KERNEL ..... OK
In the file /etc/apt/sources.list, add :
In a terminal :
$apt-cache search kernel
$apt-get install kernel-image-2.6.12-2-multimedia-386
$apt-get install kernel-patch-2.6-realtime-lsm
> MODULES ..... OK (except virmidi)
In a terminal :
$lsmod |grep snd
You need to have :
snd_seq_midi .......... OK
snd_seq_midi_event .... OK
snd_seq ............... OK
snd_rawmidi ........... OK
snd_timer ............. OK
snd ................... OK
soundcore ............. OK
If you don't have one, execute "modprobe" in a terminal.
For example :
FATAL: Error inserting snd_virmidi
idi.ko): No such device
It was OK with ubuntu kernel !!!
$modprobe realtime any=1
$apt-cache search alsaconf
$apt-get install alsa-utils
Then you have
> JACKD ..... OK
$apt-cache search jackd
$apt-get install jackd
> QJACKCTL ..... OK
$apt-cache search qjackctl
$apt-get install qjackctl
Set qjackctl with jackd, not with jackstart
with jackstart :
#12:12:42.618 Patchbay deactivated.
#12:12:42.906 Statistics reset.
#12:12:42.980 MIDI connection graph change.

#jackstart: cannot get realtime capabilities, current
capabilities are: # =ep cap_setpcap-e

#12:12:46.263 JACK was stopped with exit status=1.
#12:12:48.268 Could not connect to JACK server as client.

I import some hydrogen samples in rosegarden, and I don't have any
sound. Does somebody have an idea ???
May be this is the virmidi module which is not loaded ?
