Thnak you falk. I'm experimenting random x-runs with settings I usually used to set for mixing/monitoring rather than recording - like 1024 @48000Hz. Apparently, they occur randomly and they do not appear on the logs but only in cadence icon in Unity. I'm currently using the bridges as I use my kxstudio installation for almost everything - browsing, studying, documents, etc. While writing this post the number of xruns detected increased to 10 in almost 45 minutes of computer usage - mainly browsing and writing documents; I can't figure out why. Also, the bridges auto-start while i login; i had manually activated them yesterday as they didn't - at least pulseaudio bridge, wich was necessary to me. This isn't a problem at all; i just thought I had to let you know. Anyway, your work is really great; cadence apps are awsome.

Unity by itself takes a lot of CPU, so some actions like alt+tab in rapid succession might trigger an xrun.
The problem comes when xruns happen while the system is at rest - that should not happen! (maybe there's a background app indexing files?)

About the random xruns, they never happend so frequently before - even with high resource usage programs going on. I used to have one in 2 or 3 hours, and not every 10 minutes. Plus, xruns where usually related to random Ubuntu internal crashes, wich seem to happend often with this release. By the way, I'm planning a composing session this afternoon, i'll let you know how it goes.

The bridges should still work as before, the GUI for them is just missing at the moment. If not, consider it a bug. Is this the case?

Everything is fine with the GUI and all. No bug in this case.

Hello.

I am new in this forum (and sorry for my English).
First i want to thank "falkTX" for "KXStudio"

.

So, after last update i have a problem on notebook and desktop pc (both use Kubuntu (KDE 4.8.4 and 4.9) + KXStudio).
In "Renoise" i can see plugins (ladspa, vst, dssi) only with "sudo", "Ardous3" can see only LADSPA, "Lv2 rack", "ZynJackU rack", "Jack rack" don't see anything and so on.
I try configure manuly new path but seems it's dont work.

Ps. Im not a big "Linux" master so sorry for my misapprehension

Reset not helped and i never run programs with "sudo"

I reinstaled KXStudio on notebook the day before yesterday and its worked good with older cadence but after update, and new cadence it's faill again with plugins path .
Desktop

All my plugins are in /usr/lib/
I tried to copy to another location (/home/polis/.dssi) but it did not help.
Thanks

EDIT:
oh, it didn't realy resolve it, sems to be a problem with the packages for me, i compiled from Master and it seems to work.
Just the packaged version doesn't:

similar for the other tools,
missing files, i guess, i'll play around with that a bit.

Hi again,

I composed a little this afternoon and it didn't give me strange xruns during the session. However, leaving it idle for 2 hourse gave me like 25 xruns (studio still loaded). It could be because of some programs in background indexing as you said, but it never happened before..and there again, no way i can find in the log any xrun. It's some strange to me..

Another issue is: claudia launcher, if started from cadence, starts programs independently form claudia - they do not appear in claudia while launched.

Third issue: logs window do not start when launched from cadence unity icon.

So far now, no problems.

Cadence seems to be working for me so far. This is not a bug report, but a small feature request. I was wondering if you could recreate the cadence --minimized capability? I really like starting Cadence automatically at boot and having it minimized on start, which is no longer happening now. Many thanks for your excellent work!

If you find more info about this, please report back.

Ok! I have to say i had a jack update a while ago and didn't use my machine for a couple of days, so maybe I didn't notice the problem before..in 1 hour of web browsing i am now at 46 xruns, and no single one in the logs. I mean..lol this IS strange!

falkTX wrote: "This is not a bug but a feature"
(It will be properly documented later, but yes, it's intended).
Claudia-Launcher has the ability to start apps outside of ladish (and that's why it exists as a separate app), and that's what it does when ran outside of Claudia's Add-New option.
(Note: The 'Cancel' button should be 'Close' in there)

Well this explains a lot! I was wondering for a while if the existence of claudia-launcer made sense..now it does

Working after update. Perfect!

Double post. I guess I found out what caused the random xruns issue: Jack priority was put back to 10 (normally it's set to 87), I don't know why. Setting it back to the previous value fixed it. I also reconfigured jack and I had problems selecting the right interface - I must select hw:0,0 to make the server start, and I could only select hw:0 in the cadence menù, without other possibilities - it didn't show me any other card, nore in input and output devices. I had to set everything with the linux audio configuration tool, log out, log in again and it worked. Setting from cadence did not work and I couldn't start jack, no way. Also, every time the server wouldn't start some parameters in cadence jack config menu would reset - in and out channels, midi driver, frequency. Seems that a non-bug has made a possible problem emerge..I wonder if someone else has this kind of issues.

Hi falkTX,

I've got the same problems as hellalive with cadence and jack. Not all interfaces are showing. Restored claudia sessions crash jack. Problems with sound cards.

Been like this since Monday.
Hope this helps.

Hi falkTX,

Just updated and it is still broken for me!

b4rney wrote:Restored claudia sessions crash jack.

This is also related to the hardware detection I think. I have an Alesis IO2 usb adapter. The sessions are usually saved with this hardware configured in jack. If I restore a session without the Alesis attached then jack crashes. When I look at the cadence jack interface it shows hw:3 which doesn't exist.

Before this week it was simple to recover by reconfiguring jack (inside cadence) and the session would suddenly work. Recently I don't think the hardware interface detection is working.
Hope this helps.

Hi, I am trying KXStudio on Bodhi linux, a light distro (500MB) with E17. Nice.
Everything seems to be running fine although my midi devices are not present in the patch bay, other than the midi in and out of my firewire interface a focusrite pro24dsp. These are found during boot (snd-usb-audio and emu10k1) and were present in earlier versions. Also Cadence in the system tray does not display the usual info, a minor issue but useful.
Amazed at the ease you have brought to configuring linux audio.

1-start Catia
2-stop A2J bridge (tools menu)
3-enable A2J HW export (set to yes)
4-start A2J bridge
the hardware MIDI ports should now appear on the canvas.

Ah yes, and so they did

Would running update settings have done the above?

Cool. Many thanks.
