Hi Oliver,

Are you asking if it’s possible to make plugins around libPd, or whether there is a generic way to port Objective-C UI’s to other platforms…?

Re: libPd, my understanding is that it is not possible to host multiple instances of libPd within the same process due to libPd’s extensive use of global state. I noticed that someone has been working on an alternative to libPd called Pd++, which claims to solve this problem, but I can’t vouch for how stable / full-featured it is as I haven’t used it: https://bitbucket.org/resler/pd-audio-unit-plug-in/
