Hey Aaron,<br>
<br>
I always had issues with the Calf plugins when they were in
development, i.e. with some alpha or beta builts from svn (or
whatever they use). This was a while ago. So I would make sure that
you have the newest release of the Calf plugins, not some older
versions. They were quite a while in development, so people used
them when they weren't completely ready to be used.<br>
Apart from that, I guess it's nearly always the plugin's fault if
something goes wrong, most plugins work quite well with any Ardour
version.<br>

<pre wrap="">Also posted this on the forums but I know there is a preference for the
email list or IRC and I’m not much of an IRC guy so here goes . . . .
Not sure where to go with this since I don't know who owns this issue. I
had been running A3.2 on AVLinux 6.0. It seemed like Calf MultiBand
compressor was using way to much CPU when the gui was up - no issues w/o the gui. I figured it was because of my Compiz settings and perhaps one too many tweaks . . .
In any case, I re-built my system with AVLinux 6.01B. I put A3.3 on and
left the AVLinux builds as well (a really late 3.1 build, I think). Now
it seems, if I leave the gui for Calf compressor up for more than a few
minutes, something bad starts happening and I can watch CPU usage
gradually go up until audio starts dropping and the whole thing locks up in some kind of weird state. No problems as long as I don't bring up
the gui for more than a few minutes.
I've replicated this several times, both with the AVLinux build and the
fresh 3.3 build. Also, the version of the Calf multi-band compressor is
about the 3rd or 4th version I've seen recently, it seems. This version
adds the visualization of the filters.
When the system gets into this state, I can watch a system monitor as see
very high CPU usage from Ardour even though nothing is happening
(playhead stopped, no sound, etc).
Any ideas? If I had to guess, I'd say the version of Calf Multiband
compressor packaged in AVLinux 6.01B is problematic but I don't know.
Other factors changed at the same time (A3.3, AVLinux 6.01B).
Unfortunately, I’m only marginally capable but if there is anything I can provide that will help you help me, let me know and I will do what I can.
I originally sent this to the 'bounce' address so this may be posted twice. If so, sorry about that.
Thanks.
Aaron
