I'm writing a software audio synthesiser.

Not quite the same as I'm not following or reimplementing any established standard, but it's interesting and fun to Greenfield a c++ project using minimal dependencies to do things like:

- invent and parse a DSL - modularise components and connections between them - possibly cyclic directed graph traversal - efficient near-real-time audio processing (working in chunks within a time budget) - multithreading / parallel module processing - spit the outputs into an audio device and/or wav files - eventually put a GUI on top
