It seems iiwusynth tries to read MIDI data from a raw MIDI port, but you want it to run as an ALSA sequencer client. Try -m alsa_seq -a alsa. I've tried this and iiwusynth now starts up: iiwusynth: debug: Using alsa audio driver iiwusynth: warning: Couldn't set high priority scheduling for the audio output iiwusynth: debug: Using alsa_seq MIDI driver iiwusynth: warning: Couldn't set high priority scheduling for the MIDI input and hangs round waiting, I suppose, for input. It is hogging the audio output alright because I no longer get audible output from timidity, and kmidi says that /dev/dsp is busy. However Rosegarden still says sequencer exited and AudioPluginManager::fetchSampleRate - couldn't fetch sample rate. I've been wondering if it is my /etc/modules.conf that's at fault. Should it have something like alias sound-service-0-2 some module or other to provide service #2 (I gather this is midi) for soundcard 0? I've tried to load snd-seq-midi.o using modprobe but it doesn't seem to make any difference. Thank you very much for your patience!

[Alsa-user] /dev/sequencer no such device, but audio plays ok?
I've installed the alsa drivers and can play and record sound ok, but /dev/sequencer cannot be opened - I get the ENODEV no such device error. I have a Realtek ALC650 audio on motherboard and RedHat 8.0 (which misconfigures the audio in /etc/modules.conf as alias sound-slot-0 via82cxxx_audio, a known bug). From the Realtek website I was directed to use the alsa drivers and to set my /etc/modules.conf with alias char-major-116 snd options snd major=116 cards_limit=1 #--- Via8233 --- alias snd-card-0 snd-via82xx options snd-via82xx index=0 id=Via8233 #--- alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss #= looking at snddevices it will have created /dev/sequencer with these values mknod -m 666 /dev/sequencer c 14 1 but here I lose the trail - is there a fundamental problem here - am I talking to some missing hardware?
