[expr] / [expr~] are C externals which must be compiled and statically linked on iOS as dynamic linking is not allowed. This is against the GPL, so I can't include GPL code. However, as my app is open source, I can use LGPL code.

Patches, on the other hand, are simply text files. The GPL requires that users must be able to freely update/modify GPL objects. Obviously you can't do that with a statically linked library, but you can with a text file. All patch abstraction libraries will be in the Documents folder where you can update them over WebDAV. The app simply adds any folders it sees to the search path, although I'm considering [declare] as a standard of practice.

i'm not sure i understood correctly.

you say you left out [expr~], [expr] and other GPL code
out due to licensing issues, but i'll still be able to use/modify
GPL patches.

Hmm, will we be able to add these objects with a path of sorts,
or are they strictly off limits?

Correct. RjDj like + visual scripting.

I know [expr~] is now LGPL, but I'm not sure about [expr] yet ... in either case, I've left them and any GPL code out so far due to Apple's licensing. GPL patches, however are kosher since they are not compiled and you'll be able to modify/update them.

Also, the app has a desktop version ...
