I had virmidi working fine with 10.4 Lucid but since updating to 11.04 Natty I cannot make it work. I have followed the HOWTO [url] http://tldp.org/HOWTO/MIDI-HOWTO-10.html[/url] which is the best and about the only reference I can find. It's out of date but I've done my best with it. I have installed the standard 11.04 installation as an update from 10.04 - generally everything is fine, just this one problem. My installation includes:- paman - Pulse Audio Manager pulseaudio pulseaudio-module-jack qjackctl jackd1 (I can't get jackd2 to work) aconnectgui - midi router vmpk - virtual midi piano keyboard timidity - midi synthesizer Here's what I've done:- [CODE]/etc/modules # /etc/modules: kernel modules to load at boot time. # # This file contains the names of kernel modules that should be loaded # at boot time, one per line. Lines beginning with "#" are ignored. lp snd-virmidi index=1[/CODE] virmidi seems to load fine [QUOTE]tony@ubuntu:~$ lsmod|grep virmidi snd_virmidi 13064 0 snd_seq_virmidi 13309 1 snd_virmidi snd_rawmidi 25269 2 snd_seq_virmidi,snd_seq_midi snd_seq_midi_event 14475 2 snd_seq_virmidi,snd_seq_midi snd_seq 51291 8 snd_seq_dummy,snd_seq_virmidi,snd_seq_midi,snd_seq_midi_event snd 55295 19 snd_intel8x0,snd_ac97_codec,snd_pcm,snd_virmidi,snd_seq_virmidi,snd_rawmidi,snd_seq,snd_timer,snd_seq_device tony@ubuntu:~$[/QUOTE] I put these lines in /etc/modprobe.d/alsa-base.conf [CODE] # mods for virmidi # Configure support for OSS /dev/sequencer and # /dev/music (aka /dev/sequencer2) # (Takashi Iwai advises that it is unnecessary # to alias these services beyond the first card, i.e., card 0) alias sound-service-0-1 snd-seq-oss alias sound-service-0-8 snd-seq-oss # Configure card 1 (second card) as a virtual MIDI card alias sound-slot-1 snd-card-1 alias snd-card-1 snd-virmidi[/CODE] the sound stopped working altogether so I took them out again.

I can use either qjackctl or aconnectgui to make the virtual patches. I test thus:- 1. start timidity 2. launch vmpk virtual keyboard 3. edit connections in vmpk to send output to a timidity port 4. play the keyboard and I can hear the piano 5. edit connections in vmpk to send output to virmidi port 6. change the connections in aconnectgui [IMG] http://www.wikiwhatever.com/aconnectgui-1.jpg[/IMG][IMG]http://www.wikiwhat… 7. play the keyboard and there is no sound 8. conclusion: virmidi is not working. If anyone can shed any light on this I would be grateful. Tony
