polyphonic synthesizer. the synthesis itself is pretty simple, the most interesting here is the polyphony. awkward to do in such a limited language as jesusonic, with no structs, macros, functions, preprocessor or anything. so, this is far, far from optimized. i paid more attention to the struct-like things, and keeping it simple to experiment with (code-wise). will continue to add small functions, until i feel the 'architecture' is working as i want, then optimize, unroll memory handling, etc..
