There is no option for the current beta because I haven't got around to adding it yet. Sorry about that. It will probably be a month or two before I get a chance to look into it again.
I really don't because I could never find a working solution. I spent quite a lot of time with this in the past and I got really frustrated by the whole thing. My frustration was born out of a very slow development machine, and differences between the AU and VST specs. I will revisit it soon though as I'm very anxious to have Cabbage available to users of Logic.
A copy of the current .csd when exporting it embedded into the .vst bundle. On Windows a copy of the current .csd file when exporting is placed into the same directory as the .dll. it's important that the dll can read the .csd file from the same dir. Things a neater on OSX because it will always be in the right place, i.e, within the bundle. Note that if you wish to bundle 3rd party files with your VSTs use the bundle() identifier.
All you have to do is make sure the Csound64Lib.framework (I think that's what it's called, not on OSX right now) gets placed into /Library/Frameworks, that's the system Library folder, not ~/Library. if it's there Cabbage should work just fine. I uses packages on OSX, which is now open source. it lets me select payloads from disk which it then installs to the same location on the users machine.
Hey that looks sweet! I'm delighted you guys are using Cabbage now I thought you guys only did bundles? Are you now producing synths too? And thank you very much for the donation. it's always appreciated!
