As a followup to last week's post, I put together an abstraction that works like csound's "gbuzz" opcode. Quite a bit more cpu-hungry... could maybe do with fewer options. If anyone has any efficiency ideas I'd welcome them -- the algebra is convoluted -- something using [expr~] would make things work better maybe. I did use [expr~] for the one audio "pow" operation to make this mostly compatible. Also uses [abs~].
