I'm hoping someone can help me with getting sound from MIDI on my
computer. I'm currently running Ubuntu 10.4.1 (lucid) on a laptop with a
Linux trili 2.6.33-29-realtime #1-Ubuntu SMP PREEMPT RT Thu Aug 5
12:28:39 UTC 2010 i686 GNU/Linux
but I have had pretty much the same experience with Ubuntu Studio.
I have alsa, but have not installed pulseaudio.
I am not using any external MIDI devices.
I'm just not getting any sound out of MIDI programs. Alsa seems to work
OK: mplayer, vlc, etc. work. I can play a MIDI file using Timidity,
because that converts it to wav format. But programs like seq24,
aplaymidi, Midi Virtual Keyboard (vkeybd), jack-keyboard: nothing.
MuSe starts, if Jack is running, but soon ends with:
looping waiting for sequencer thread to start
midi sequencer thread does not start!? Exiting...
At least it's an error message...
Rosegarden has played some of its example music, but I think it's
bypassing jack and midi when it does. Furthermore, it's not at all
consistent, as far as I've been able to understand: I think the audio
device or program environment that it requires to produce sound is very
fragile, and I have not been able to determine how to make it more
robust. Even the documentation says sound in Rosegarden is a complex
So: I've thrown out a bunch of stuff here, and don't really know what
I'm doing. I don't even really know what they mean by a "sequencer":
something that sequences a thing that was otherwise un-sequenced, I
guess. More likely: a program to play some kind of sound file.
Is there a simple way to test my MIDI configuration? A simple app I
should use to test and debug it?
Thanks for any help.
