Hi, I've another issue in qtractor 0.61 for you - this time on Xubuntu 14.04. It's around lv2 plugins, and general instability. LADSPA plugins work very reliably.

I've experienced issues with the following plugins, all lv2 -

Many of these aren't essential to me, just randomly testing a few I happen to have installed. I'd love to have the calf plugins working, but I've read on kxstudio somewhere that they removed plugin support - so would this no longer be possible? Do I have to use Calf Rack? I'd like to keep the automation...

I've unchecked all of the experimental plugin settings for safety, which hasn't made any difference. Interestingly, the following is dumped in the message box on occasion, I think when loading track properties -


(qtractor:21421): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed


(qtractor:21421): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed


I also get this more rarely (note the colour, it's beige if the list resets it) -

Or -

I presume these would be due to erroneous plugins. Would it be worth me installing the debugging symbols to investigate further? Or is this just a matter of uninstalling all the bad plugins - I've got all the plugin packs from the Ubuntu / kxstudio repos. Can anyone recommend a decent, reliable source that gives me most common functions (decent delay, reverb, filters etc)? Or should I just be using LADSPA?

Thanks
