You need to subscribe to the list to be able to post to it

You must run with –rt flag. See the /usr/share/applications/pd-l2ork.desktop
file and here’s the start-up sequence if you wish to use command line:

pd-l2ork –rt –jack –audiobuf 5 –inchannels 2 –outchannels 2 –alsamidi

I am not sure what you mean by it not being as stable. Is it crashing? If
so, you should report when and how. I am not currently aware of any crashes
with pd-l2ork. In L2Ork we keep pushing it to the very limits and we haven’t
had a single crash in over 6 months with over dozen users using it twice a
week for 2 hours.

If by stable you are talking about xruns (A/D/A sync errors), you can
increase pd buffer size (with –audiobuf 50), as well as JACK buffer size
(when you start JACK). These have nothing to do with pd-l2ork but mainly
with how your system is set up.

Thanks for your quick reply Ico and Hello to the mailing list! 
I tried to start pd with or withour -rt and it didn't change it's behaviour.
I'm running DreamStudio 64bit with Lowlatency Kernel 3.2.0. 
I noticed that the following Error occurs, no matter which audio driver I
try to select ( A/D/A sync in an endless row see the report at the end of
this mail):
Strange is, that there is "normal" sounding audio output when using jack but
the whole app isn't stable as it was expected to be. 
Can someone help me out? 

Thank you very much indeed!

Hi,

I would suggest using l2ork-dev mailing list for questions like this.

See:
http://l2ork.music.vt.edu/main/?page_id=57
http://l2ork.music.vt.edu/main/?page_id=33

As for your question, it is difficult to say where the problem lies. Did you
start JACK with RT flag enabled? Is your computer running a lowlatency
kernel? Do you have audio group with RT privileges? Did you start pd-l2ork
using a shortcut from the menu rather than just typing pd-l2ork on the
command line? I am sure I am missing questions that I haven't asked, but
this should be a good start.

Best wishes,

Ico

Hello Ivica Ico,

I'm trying to install L2ork on Ubuntu 12.04 with DreamStudio Distro and
I'm getting permanently A/D/A Syncronisation errors when starting DSP. I
couldn't find any mailing list or support pages, so I decided to email
you directly. I hope you don't mind?
Maybe you can help me with this Problem?
I read about L2ork because I already had problems with Standard
PD-extended (Freeze after DSP on/off). You recommended on the pd-
Forum
to try it with the version submitted on dr. Graefs ppa and so I did...

Thank you very much indeed!

Johannes
