Always interesting to see this. Looks a lot like a 4k synth I did myself many years ago. It also amuses me to see that almost everybody was using those RBJ biquad filters.
I have to confess that I have pretty much no idea how the filter works or the math behind it. I wrote that part with a friend who has some DSP background but it was essentially copied from a signal processing book :)
But it sounds alright and was easy to implement, I can see why it's popular.
