[linux-audio-user] getting fluidsynth to read from ALSA seq

[linux-audio-user@xxxxxxxxxxxxxxxxxx (Adrian Prantl)]

Hello!

Today I tried to use fluidsynth as a software synthesizer to Rosegarden4.
I followed the tutorial at 
http://linux-sound.org/quick-toots/4-sequencers_and_softsynths/quick-toot-midisynth_howto.html 
.

But when I try something like
> fluidsynth -m alsa_seq -a alsa -o "midi.alsa_seq.device=VirMIDI 2-1" 
midi/gs.sf2 
fluidsynth reports:
> ALSA lib seq.c:181:(snd_seq_open_noupdate) Unknown SEQ VirMIDI 2-1

So my question: What is the correct name for ALSA sequencer port 81:0?

thanks,
  adrian
