There’s the newly open source code. Heavy compiles highly effiecient and optimized C code from patches (you can only use a subset of objects, but they have stand-ins for ones you might miss).
A lot of options are for embedding patches into other development environments. But it can create VST’s from your patch, and possibly externals for Pd (there’s a generator called Pdext). If so, it would be a great way to turn subpatches/abstractions into resource efficient objects. There’s also other options for optimizing code for your hardware (like embedded ARM applications).
This is a great resource, and now that its open source it would be great to see it adopted by the community and actively developed. I personally wouldn’t mind seeing this code find its way into things like Purr data. It might be useful for a “performance mode” or something similar.
