Muse2 fails to start

[angelsguitar]

When trying to start Muse2, I get the following:

Code: Select all

QGtkStyle was unable to detect the current GTK+ theme.

ALSA lib conf.c:3770:(snd_config_update_r) hooks failed, removing configuration
Could not open ALSA sequencer: No such file or directory

Tried sudo modprobe snd_seq but still get the error. Other MIDI programs (Rosegarden, Qtractor) work without problems.

I'm using the latest Arch Linux. All Alsa base files are installed. No other issues with sound.

What am I missing?

The source of trouble is the guitarix_ladspa plugin.
Witch version of guitarix do you have installed?

Solution for now is, simply delete /usr/lib/ladspa/ladspa_guitarix.so

after that muse will start normal again.

Thanks for your reply.

You were right. I was so focused on the last part of the terminal output that didn't pay attention to that part. Guitarix 2 was the source of the trouble. I was using version 0.22.0-1 for the AUR. Seems the LADSPA plugin of that version was giving problems with Muse 2. Updating to the latest version (0.22.3-1) solved the problem.

Thanks for the help.

Nice to hear that a update work. The bug in the ladspa_guitarix plugin was on of the reasons why we release version 0.22.3. That's why I ask witch version you use.

[angelsguitar]

However, something unexpected happened...

After I updated Guitarix, Rosegarden did not start I had to uninstall Guitarix 2 in order to be able to work in Rosegarden, which is my main MIDI recording program.

I'll give it a try again, and post back any error messages I get.

Yes, that is fixed in our git with this commit:
http://sourceforge.net/p/guitarix/git/c ... dbb4ac3cc/
So please wait for our next version, witch will come soon.
or, if you need to use guitarix standalone, delete (for now) /usr/lib/ladspa/ladspa_guitarix.so

That LADSPA plugin seems to be giving a lot of headaches!

Well, glad you sorted it out. Thanks for the info, see you around.
