You can make yourself tilde externals for pd, that you embed in your 
libpd-based app... e.g. one or two outlets, no inlets.

You just call the setup-functions of the externals just after initialising 
libpd... the externals don't need to be separate files (dll, so, dylib) : 
they can be part of your main executable instead, which is easier.

I already do that with non-tilde externals. (Haven't had a reason to make 
tilde externals in that context yet).
