In case anyone is following this thread - I've noticed some more "funnys" with the DMG plugs - with stereo and mono interleave settings. I just realised that the "dots" in the FX bin tell you if a plugin is loaded as stereo or mono.
VST3 Compassion - is fine
loads stereo, changes to mono if track interleave changed
changes to stereo if track interleave changed
VST2 Compassion is loading as mono! (on a stereo track)
if track changed to mono interleave - it stays mono - but track cannot be put back to stereo
mono Compassion loads as stereo! (on a stereo track)
loads as mono on a mono track
compassion - no sc
if plugin set to "enable mono processing" - will not load (crashed SONAR)
if not set to "enable mono processing" - loads in stereo
VST3 Equilibrium - is fine
loads stereo, changes to mono if track interleave changed
changes to stereo if track interleave changed
Equilibrium mono loads in stereo on a stereo track
changes to mono if track interleave changed
then if track interleave changed back to stereo - stays mono
VST2 Equilibrium
loads stereo
track cannot be put in to mono interleave with plugin set to "enable mono processing" set to enable or disable
I don't know if any of this has anything to do with the inability to save settings - but it certainly has everything to do with causing crashes - and this "mono stereo" issue has been a problem for me since X3 came out (everything was fine in X2). I got around the problem by using the VST3 versions - which was fine until they stopped being able to save their settings...
