[sdiy] square to sine

[cheater cheater]

What a welcome! Highly appreciated, Neil :) Don't worry, I won't stop
thinking about synth diy even if I live out of a paper bag ;)

Dave, I'm going out on a limb here, but this reminds me of a technique
normally used for asynchronous sample rate conversion, which is
"flywheel sync". Basically, you have a model of a flywheel - with
torque and friction - and each rotation of it is one output wave
cycle. As clocks come in, you give the flywheel a "push" or "jolt". If
the jolts stop coming in, the flywheel stops eventually. If they come
in at a lower frequency, the flywheel spins slower. If you rapidly
lower the frequency, you can add some friction (for example, friction
gets -df/dt added to it). It is normally used to prevent jitter, but
can also be used for syncing two different waveforms together.
