sequencer problems

[Pierrick Hanlet]

I'm using Scientific Linux5.1 and am attempting to run RG.  In starting RG I get the following error
message:

AlsaDriver::initialiseMidi - couldn't open sequencer - No such file or directory - perhaps you need to modprobe snd-seq-midi

When I attempt to "modprobe snd-seq-midi", I get:

FATAL: Module snd_seq_midi not found

Google has ony 3 links to this message (1 in Chinese).  The other two weren't helpful.
Now what do I do?
Thanks,
Pierrick

First you can check it the sequencer module is in the kernel, and not as a
module, by doing "ls /proc/asound", if you can't find a directory named seq,
then you most likely have to reconfig and rcompile the kernel (open
up /usr/src/linux/.config in your fav text editor, and make
sure 'CONFIG_SND_SEQUENCER=m', and then make all modules_install. then you
might try to modprobe snd-seq-mid again)

Some distros don't load that module by default, which is why I added those
instructions to Rosegarden.  What you have is an entirely more complicated
situation.

How far as you willing to go to solve this?  This problem is probably only the
tip of the iceberg for you in terms of the complications you're going to face
trying to run Rosegarden on that distro.

These days, trying to get Rosegarden to do anything on a distro that isn't
studio-oriented (eg. Ubuntu Studio, 64 Studio) is pretty much an exercise in
pushing a boulder up hill.

Well, wasn't so hard as that on Debian Etch here ... just installed
fluidsynth and pointed RG at it.

Dealing with JACK was like pushing a boulder up hill. ;-)

OpenSUSE deals with sound in extraordinary good way for a casual user
(not musician). Even found (a bit hidden from a user) option to
automatically load soundfont on startup. If sound card is determined to
be capable of doing it, of course.

About JACK... The same thing. Just adding three simple lines to
limits.conf file made my system usable for audio, too.

My laptop comes equipped with a state-of-the-artless Intel audio
chipset. I'd be surprised if it supported loading soundfonts!

You didn't mention the first step: run a RT kernel. But my problems with
JACK weren't of that variety. Some kind of lib or version conflict,
IIRC. I keep saying I'm going to set things up properly on the server,
but never seem to find the time for it.

What did you do?

Don't you also need to install an rt kernel?

Started Yast -> System -> /etc/sysconfig Editor and under
Hardware->Soundcard I have possibility to tweak various things like:
loading sequencer module, sounfonts and oss modules.

At my surprise too, no! It works very well for a few audio tracks
simultaneously. But, yes, I have -rt kernel too, because it was easy one
to obtain. I think it's in the main repository.

I've just saved you of stroke! :) No hardware synth fun for you.

I agree.
Compiling kernels can be even more frustrating and time-consuming.
Instead of giving up in depression, keep yourself happy by
using an audio-distro and run RG "OOTB".

If you're accustomed to use Suse, try jacklab.
Maybe the live-CD is enough for your requirements.
Some live-CDs can be installed in existing filesystems,
in case you want to keep Scientific Linux.

http://jacklab.net/jacklaborg/english/?JackLab_Audio_Distribution

Another option would be to try to install the rt-kernel from the jacklab-distro.
Though I have no idea (I guess no), if that would solve all problems
with running audio properly.

That's why I use fluidsynth - it loads soundfonts just fine when I start
it. ;-)
