Blank screen in OS X El Capitan, errors in Processing

Hi,

I'm trying to test MusicBeam on MacBook Air/OSX El Capitan with projector set as second monitor, and it's not working.

It's giving a blank/black main screen with no UI or anything at all.

I've tried opening the MusicBeam.pde in Processing, and installing the libraries as described in the readme file, and it gives errors when running in Processing which make me think one or more library is not loading correctly - eg. line 26 "Stage stage = null;" give the error "The class "Stage" does not exist", and likewise for many classes thereafter.

Any help appreciated.

Thanks,

Andy
