I think you'll want to start with libpd, since it strips out a lot of the GUI stuff, which definitely won't be needed ;). Then you'll need to get it compiling, then you'll need to write the audio I/O method.
You'll need to put in some kind of hack to replace loading a patch, like having the patch as a compiled-in string. .hc On Apr 3, 2012, at 5:10 PM, Damian Stewart (ML) wrote: > hey Hans + Miller, > > thanks for pointing me towards Sukandar's work. > > so to be clear: you think i'd be able to take the Pd source code and just > push it through the DSP's compiler and something vaguely usable would come > out?
