Thank you very much for the fast (and inspiring) answers, @SmashedTransistors ! (I also learned right now how to make better use of the scopes ...)
Using tiar/dist/fold sounds also interesting, but it is not the "natural wrapping" of if phase in 2pi space I intend to implement.
Thanks also for the second post including the patch. I tried similar things before with osc/sin, however since I want also potentially complete static sounds, this might be not my solution, so I useda "osc/sine lin" @ frequency 0 . Frequency cannot be exactly 0 at osc/sine , correct?
I observed in your patch that if I increase the bit shifting at math/<< further to 5 or above, the numbers "fold back" and the overtone spectrum is reduced again. This seems natural based on the mathematics/number formats (probably) used here. I do not know if this is a property of K, the following VCA or the sine oscillator phase inlet.
BTW, where can I read an introduction about the used formats (for K and S), "number spaces" (bits and ranges) used, normalized value height , ... in the axoloti platform. I was afraid, I will have to do this in near future ... (Sorry, if I do not yet use the correct terms ...)
It could also be that the value jumps in my solution using modulo and sine lin´s phase input are generated just inside the osc, and not already inside the modulo module. I will check this in more detail soon ...
Thanks again and regards!
