I'd like to port this to C++ for the purpose of manipulating MIDI data in real-time.
If this would be of any use to others, I'll be working on it here: https://github.com/godofecht/isobarcpp
Rationale:
Some of the developers we work with prefer to use Isobar to manipulate MIDI, set up Markovian Processes, and generate tracks. The model makes sense, and we'd like to reduce the transferral time from Python based prototypes to C++ functionality further.
If anybody can suggest a better alternative, or perhaps... a c++ library that already exists that Isobar was based off of, I'd be super interested to know more.
