Re: SupercolliderAU

Hello. Yes in general it is maintained although only in source form, and
the overview help file in SC is outdated at the moment.
Making plug-ins with AudioUnitBuilder does not fully work.
If you find reproducible crashes and can get a stack trace (e.g. look in
Console.app), feel free to open an issue in the SCAU GH repo
https://github.com/supercollider/SuperColliderAU/issues

best,

gerard
