An object I never use....[sah~]. The helpfile is very clear about what it does (and how, and why). But i stumbled across this very simple synth on youtube, which produces some really wild timbres and I simply can't envisage what it's doing. I understand the theory and practice of FM/AM synthesis (which is what the synth appears to be doing), but could someone take a moment to look at the patch and add comments, for a math-phobe. Thanks

sorted; just spent a bit of time with it; it's fun! Here's a commented version:

Thanks for this. I love these versatile little pea shooters. I am not 100% sure what this sweet little patch is doing just yet, but I have to bump for interest, since it is really fascinating. Thanks for sharing this wacky little synth. It's amazing how few lines of code this is and how varied the output it yileds. Hat's off to the zen master who cooked this little bugger up.

Thanks for the bump kp*, I'd almost forgotten about this little gem. This guy claims to be the originator of the digital implementation of QM synthesis:

good bump. the QM guy says one of the disadvantages is "relatively low sound quality (due to quantum-noise related nature)"...i think he meant "quantization-noise", 'Quantum noise' is defined as 'uncertainty of some physical quantity due to its quantum origin' but we are definitely working with certainty here ;-)

i don't mean to knitpick, though, wanted to say i've used sah~ similarly before and to fix the noise, slide~(or rampsmooth~) lends ease:

and i can never resist putting tanh~ at the end of everything, it's probably a weakness of mine ;)

I can't take too much credit for this; I built the patch (after shaolinmink01's at youtube), and the synthesis algorithm is Zed's (synthofmine.com). I especially liked your additions, which help tame the inherent randomness of the modulated timbres - I'd like to try and add some 'predictable-pitch' control of the carrier so it may be played from the keyboard.

...it just occured to me that this algorithm could simply form one of the modulators in a more or less conventional FM engine.....perhaps
