Carbon plugins in JUCE plugin host?

Audio Plugins

Is this possible at all? When trying to display the GUI, with some plugins (e.q. Stillwell 1973 EQ) I get a white window and then a crash:

With others (e.g. PSPAudioware effects) the GUI is displayed but not responsive (i.e. you can’t turn any knobs). When using the VST versions of said plugins in the plugin host there are no issues.

Is that a carbon plugin? Looks like a crash in the plugin’s cocoa method to me…

3

That confuses me also… but auval says it has a carbon GUI.

Can’t really see what’s going on from the stack trace - it’s the sort of bug that’d be easy for the plugin writers to debug, but very hard to figure out from the outside.

5

Ok, I’ll try to get them to debug this then.

That’s not to say it’s not a juce problem - it’s just very hard to guess exactly what it is that their code doesn’t like…
