I'm excited about the idea of a more object-oriented approach, and especially with the idea of ditching all the Tk/Tcl garbage, but I don't really see the utility of re-implementing all the DSP graph code.
depending on their implementation, it may be possible to do click-free changes of the dsp graph, which is the weakest part of the dsp engine of pd. from my understanding impossible to fully eliminate audio dropouts when changing max-like signal graph, since the implicit resource access order may change, depending on the use case.
