I haven't posted problems in a few days...because I haven't had any! I just wanted to say that this is now working really well- I tracked a song I wrote, very simple session for remembering my idea- hydrogen, a 2 guitars, bass, and a few vocal tracks, no crashes, solid, fast, everything I could have hoped for. Firewire running at 8ms latency (maybe could have gone lower, don't know, but it was not an issue). I had some issues with the rt-kernel and am not using it currently, but no need really at this point, so I'll check that out when I'm feeling adventurous again! Thanks trulan and gmaq for the help so far, and I got some help on the ardour side from linuxdsp and some people on the ardour IRC and opensourcemusicians IRC. Needless to say, now that I am up and running for real, I don't miss windows...(had to get one in, come on!).

greetings!
i am also getting better performance out of this version than out of v2, and some things which used to crash ardour once in a while are no longer a problem.
cool.

Hey guys!
Thanks...I'm glad things are working well, I am finding AV3r1 has fixed most of the issues of 3.0 Phew!
Now...Hopefully you can do what most Linux user's (including myself) find it almost impossible to do...LEAVE IT ALONE!!! :grin:
Ubuntu will always be releasing something bigger faster better, as will the rest of them Fedora, openSUSE etc etc etc. Xorg 7.5, Ext4 Grub2 are all the big news right now, the truth is if your system is working well and your hardware is fully supported in terms of a dedicated AV Workstation that is a rare achievement and believe me as the developer who is always working forward and breaking things on purpose to plan ahead you don't want to mess with the core of AV Linux right now...the waters are not safe! I suggest to update applications but leave the core apps as they are, the growing list of "upgradeable" in your Synaptic list is meaningless if your system is working well. In fact ext4 is getting some negative press as being handled poorly by recent Kernels and lacking performance compared to ext3. A testing machine is one thing a production machine is quite another!
Speaking of apps, Ardour 2.8.5 is out and as soon as the source code is available in Debian GIT I will put up a package, also look forward to Rosegarden final in February.

yes... this is the first distro i've used (and i've used many) which is nicely streamlined in a way which corresponds very closely to what i need to work with, *and* is looking excellent in terms of performance and stability. as such, it presents a compelling argument for being left alone!
there are a few minor things i need to compile for myself, but i see no real need to jump on the update bandwagon -- i've finally gotten comfortable with synaptic nagging me about things which "will not be updated".
thanks again, GMaq!

Yeah, I'm going to leave it alone. There are still some bug issues in ardour that need to be worked out but now at least since I know what is causing them I am avoiding crashes (it has to do with LV2 GUI's I think- Mike from linuxdsp was helping me and he knows more about it and has taken the appropriate steps to hopefully fix the issues- thanks Mike!). So far my needs have been pretty simple, so the deepest I've gotten is ardour, jack, and used hydrogen the other day for a drumbeat for a demo. I am looking forward to trying out some midi, am going to check out muse, but midi is not a big part of the music I make, so ardour is going to be my main program.
And yes, leaving it alone- I am realizing now how important that is. I realized that on windows I was using xp still, which is how old? Why update linux so much every day and install new releases every 6 months? I love ubuntu but now understand why av has such value for music. Good stuff Gmaq, job well done!

Just to clarify one or two things regarding the problems mentioned by mrufino1:
There are some plugins out there that really don't play nicely with ardour(or other hosts) - I really don't mean to be critical, and I welcome criticism (constructive or otherwise) of my software - the aim after all, is to make it better, but I'm just pointing out what I have discovered so people can be aware of the problems I've experienced using certain combinations of plugins.
1) LV2 FIL plugins - These are parametric EQ plugins with a frequency graph, I've found that when launching their GUI they can cause a freeze of Ardour's GUI for a very long time. This caused ardour to crash or become unstable while I was using it, and JACK would sometimes disconnect and if any of my (linuxDSP) plugins were running they would think the host app had died and close their GUI interfaces too which would sometimes create problems of its own once the host came 'back to life'
I have now updated all the linuxDSP LV2 plugins so that while they may still be forced to close their GUIs by a misbehaving or anti-social plugin, it shouldn't cause a crash and the GUI can be re-opened again.
I am working on a better solution to this, but it will likely require a patch to Ardour as well, and so I suspect will be best updated around Ardour3 release (I have submitted the details to Paul Davis and I await his decision on how best to address the problem)
2) Calf plugins in the Ubuntu repositories - I tried the Calf Compressor on Ubuntu 9.10 and while the Calf GUI would open and work, if I closed it and then deleted the plugin from Ardour I got streams of Gtk+ CRITICAL messages, and an eventual crash if / when I stopped the transport. This was without any other plugins being loaded / used and appears to be a problem with the Calf plugins.
3) 'denormal' problems - Calf plugins, as well as the recently released EQ10 graph EQ that appeared in a post to the Ardour website - typical symptoms are a steep rise in CPU usage when playback is stopped or the audio is silenced, returning to normal once the audio starts playing again. Typically this affects Intel CPUs. Sometimes this will also cause a GUI slowdown and / or jack disconnects which - is not so good.
4) I've also experienced very nasty pops and bangs from the EQ10 when moving its graph around to change the EQ parameters. Its filter parameters appear not to be interpolated, which means you should move the controls (very) carefully.
I hope this is useful - it's not meant to be a criticism of anyone else's work, just some issues that I've discovered (and spent a lot of time trying to track down...)

And I definitely didn't say it as a criticism of anyone's plugs, I respect anyone who is even trying to make this all work! I know that all of these issues will be sorted out in time. The thing that I love most about linux is the collaboration between folks, it's nice to see, especially after just dealing with ilok and waves issues, trying to sell them off to leave windows. Watching something develop openly, instead of paying tons of money for a commercial app and having it not work with really no explanation, is much more fun!

Guess I shouldn't be selfish and expect all the work to focus on the A side of AV at the expense of the V side  Oh well  |
