I have tried as root and non-root and I have tried all
the MIDI output devices. But KMid just spews a load
of ALSA messages. First some `Couldn't allocate
queue' messages, then a load of `AlsaOut::eventInit :
no source'.
I have tried `Test MIDI' in Control Centre too, with
no joy.
What's happening? Or not happening?
Hi Mathew. The only Creative soundcards that you can play midi through are the
EMU ones that have a hardware wavetable synth. Open a Konsole (CLI), type
alsamixer. Press F2, and you will get details of the soundcard, including the
driver. If it shows emu10k1 you are ok, but there is a bit more to do.
Presuming that it is an emu10k1 you need to load a soundfont for it to work.
To load the soundfont you need to install a package "awesfx" (without the
quotes) (yum install awesfx). With awesfx installed, insert the cdrom that
came with the soundcard, open it in a file manager. With my Audigy2
soundblaster the soundfont is in. Audio/common/SFBANK/CT4MGM.SF2. Copy and
paste it to your /home/user/ directory.
There are 2 loaders that come with the awesfx package. One, sfxload is for the
OSS (open sound system), and the other, asfxload is for Alsa. On the command
line type, as root, asfxload <name_of_soundfont> . In my case this would look
like.
asfxload CT4MGM.SF2
Apart from trying to play a midi file with Kmid, you can verify if the
soundfont has been loaded by typing, as user.
cat /proc/asound/card0/wavetableD1 (changing the card No if you have more
than 1 card).
If Alsamixer shows that the driver is ca0106 the above won't work, but there
is a workaround.
Please post back. Nigel.
Hi Nigel,
Thanks for a great fix. Everything in your method worked out. In
addition, I managed to run `asfxload CT4MGM.SF2' as non-root.
By the way, do you have any tips for configuring MIDI input? I haven't
got around to plugging my MIDI keyboard into the computer yet, but I
imagine that I would need some advance knowledge.
For example, I see no MIDI inputs in the MIDI Manager of the aRts
Control Tool.
Best regards,
Matthew
