Is there a software midisynth built into Alsa ?

I can get
{ speaker-test }
to produce sound, but
{ amidi -S "90 3C 45" }
gives me
' cannot open port "default":
inappropriate ioctl for device '

Install timidity. On Debian 6.0 it sets up a software synth. You have to install some soundfont package too though.

Then there is no built in midi-synth ?

There doesn't appear to be. I use timidity to play midi. It works like a software synth giving music in games like OpenTTD.

I may have a more rudimentary problem.
When I type:

$ aconnect -o

I get:

ALSA lib seq_hw.c:457

snd_seq_hw_open) /dev/snd/seq failed:
No such file or directory

What am I missing here ?

I've got timidity and timidity-daemon installed. Install those. Then install soundfonts, say freepats. Or you could get CT4MGM.SF2 from a Creative installation disc to get classic Creative MIDI sound. If you get the creative soundfont, put the following in /etc/timidity/timidity.cfg:

Code:

soundfont /usr/local/creative_soundfonts/CT4MGM.SF2

Then try again. It sounds to me you don't have a synth at all.

Here are the MIDI kernel modules that my system has loaded:

snd_seq_midi
snd_rawmidi
snd_seq_midi_event
snd_seq
snd_seq_device

Code:

lsmod | grep mid

Would tell you if you have any modules loaded. If not, load them with modprobe.

Thanks !
Where do I find them ?

Just run modprobe <name of module>. The modules should be on your system already.

Thanks. Evedently they're not.
Is there a way to list the modules available ?

Yeah they're in /lib/modules. What distro are you using?

I found them. I had forgotten to use 'sudo'. TinyCore
