Tom7777 has been asking me about this for a while now, so here it is:
Schematic
I deliberately avoided doing _any_ optimizations to it since I mainly wanted it to be easy to understand.
The main optimization I'd do would be to strip out the "delta" calculation (delta = (y2 - y1) / (x2 - x1)) for each segment and do it with green float math instead. That way we'd avoid doing all these divisions in the code component.

Nice one stefan 😉

Looks Nice 😮 Thanks Stefan I can think of a few nice uses for this 🙂

Remember that it is far from alias free 🙂 (could be very useful for LFO usages etc though)

Which is exactly what I have in mind for it for some interesting parameter modulation 😈 🙂

I'd noticed that upon hearing it & looking at it, but it's still more than useful 😉

Cool thanks Stefan 😀

Is that why it cracles when I move a slider?

No that's why there is non-harmonic content to the timbre
The crackles are from sudden jumps in the signal caused by changing where it's going in mid-stream... (I think 😕 )

Sounds about right to me, no pun intended 😉

heh I put a de-zipper between the sliders & audio-OSC, & that seems to help alot. But I'll still get a crackle when I jump the sliders from 1->0->1. Any suggestions? Perhaps the de-zipper needs to be faster? cheers

the dezipper works at SR...
...prehaps it needs to be slower... that is have more intermediary values before reaching the new value from the control.
But I guess that's what you meant.... 😉

neat idea; made it 10x "slower", but didn't seem to work for me.
