Arch Linux

Disowning for lack of time

I have made a stable AUR package for cadence.
https://aur.archlinux.org/packages/cadence/

Please use 'cadence' instead of this package.

Cadence no longer has Carla in its sourcecode, it's now a separate project:
https://github.com/falkTX/Carla

it's not usable yet though, please give me time to cleanup the code and later make a release.

hey falk, just did a fresh pull and getting this error:

$ cadence
Using Tray Engine 'Qt'
sh: carla: command not found

Thanks for the report, should be fixed now.

for rdflib support, you need to use the py3 version.

I get the following errors:

That error is from linuxsampler, and not truly related to Cadence or Carla.
This could be worked around by forcing RPATH in Carla, but that's a nasty hack I don't want.

From what I see, the linuxsampler Arch package needs fixing.
create a file '/etc/ld.so.conf.d/linuxsampler.conf' and put there:
/usr/lib/linuxsampler

alternatively, run this before starting carla:
export LD_LIBRARY_PATH=/usr/lib/linuxsampler

Carla is not starting (I have linuxsampler.so.3 installed)

package is updated, thanks speps!

Please report any issues or feature requests here:
https://github.com/falkTX/Cadence/issues?state=open

The new repo should now be used, most things are now implemented there.
I've updated the PKGCONFIG with needed changes:
http://kxstudio.sourceforge.net/Paste/repo/2Mreq
(python3 is now used)

I don't see python-rdflib anywhere though, was it removed?

There is a forum topic for this Cadence pre-beta release on linuxmusicians:
http://linuxmusicians.com/viewtopic.php?f=47&t=10027

@speeps:
Can you please update this package using that PKGCONFIG?
thanks

Is the package "pyqt" missing in the dependencies? I got an error saying that "pyuic4" could not be found.

development is now on that new repo, yes, but some tools are not usable at the moment.
I'm working on getting a beta1 release out, please be patient.

Could this be updated for github (https://github.com/falkTX/Cadence)? Development seems to be happening there now instead.

Could not configure jack from cadence (python2 installed):

@falkTX Hey, pyliblo is now provided by python2-pyliblo, please fix dependency. Cheers

seems to require fluidsynth to install on my system, fails otherwise.

falk, yeah, by running one at a time did it... weird... and yeah, I do have rdflib installed.
thanx

@funkmuscle: Please be a little more specific.
The new dialog for finding plugins lets you set which plugins to look for. Please try one type at a time to see which one is causing it.

but I suspect some broken plugin is just hanging the discovery (the name is in the progress-bar).

ps - for lv2 you need 'rdflib' package.

hey falk, I've pulled the latest git today and now I can't update the plugins list... I hit refresh and it just keeps searching.... before this it worked but it just wouldn't find the LV2s..

@looplog:
Thanks for the report, now fixed

Just rebuilt and now cadence is failing with the following error:

Traceback (most recent call last):
File "/usr/share/cadence/src/cadence.py", line 94, in <module>
GlobalSettings = QSettings("Cadence", "GlobalSettings")
NameError: name 'QSettings' is not defined

Well, i can't entirely help you there, but lets put it like this;

in order to fix my asoundrc, i opened both files (the old and new one), then i simply cut and paste my old one into the new one.
maybe some sort of sed command could be used to append it to the top or bottom, instead of making a new one??
I suppose if it was possible, you would append it to the top of the file, as sometimes people have longer asoundrc (especially, if not using PA)

if you could do that, you wouldn't need to worry about any of the complexity, right?

PS: I love all the stuff you are developing! keep up the good work :)

The "problem" is that asoundrc is a very very complicated business, and I don't even understand it well.
How would I be able to edit it...? (Any help is welcome)

But, this project may have useful code - http://www.xwmw.org/qasconfig/index.html
I'll check it out soon and see if I can borrow something.

@falkTX

don't bother doing that (having it create .asounrc with a date). the linux file-system creates - .asoundrc~

so technically, it does get backed up, naturally anyway.

The point was more, having it overwrite that file, can screw with a user's settings. But understandably, it isn't a high-priority.

At least it is documented here, if anyone runs into the same problem.

I'm aware of that issue, but 'Cadence' is not the priority right now.
The focus is currently at the patchcanvas module, sorting it out and making it work faster (more reliable too).

I'll try to make it rename the "old" config to something like ~/.asoundrc.old-20111026 in the mean time.

i've found something that should probably be fixed in Cadence.

if you select alsa-bridge-->jack

rather than adding/appending the pcm.jack stuff to your existing .asoundrc - it instead replaces it. for some people, i am sure that is okay. But some of us have a customized .asoundrc , and require them... my external audio interface must be specified in .asoundrc, for example.

it would be nice, if the default behavior wasn't to replace an existing asoundrc. but instead to add the alsa-bridge/jack stuff to it. I just spent the last 20 minutes trying to figure out why jackdbus wasn't working, and that was the reason ~ Cadence overwrote my settings.

Updated, now builds fine again
