Ardour crash when using calf plugins
I recently started recording some songs with my band. I use ubuntu studio 12.10 and Ardour 3.1
Everything worked better than I thought they would couse i have never recorded with a band before, but we got all tracks recorded for the first song without any problems.
Then the mixing also went smooth until we where almost done...
First the sound suddenly disappeared on all tracks, but if i solo for example the guitars I get sound. And the DSP load in ardour was nearly at 100%, but now it can vary betveen 10 and 80%. Oh and I only use Calf plugins (the most recent ones) about 3 plugins per track(15 tracks)
If I mute all plugins... sound. Then I can bring back one at a time to about half of them... no sound.
And if I open one plugin sometimes it works and sometimes ardour just quits without any errors. I don't know if it's just me but Calf reverb, compressor and eq seem to fail the most.
Sorry for the bad explanation but here is a video where i try to show it:
Its only on this session so far the sound has gone like that and I dont know what to do.
I'm kinda new to this stuff so I don't really know what to do. Sorry for my bad english.
