Integrator seems a bit sqiffy as well. It pins at -256 with a sine wave input, with a little flick to something higher when it reaches 1 on the sine. Am I correct in assuming that it samples at audio rate? Even with that, I’d expect it to spend 50% above 0 and 50% below 0.
Are there any examples you can point to that uses these blocks that I can study?
I’ve fixed my current problem using a tuned allpass to give me a 90 degree phase offset, but would definately like to understand the differentiator and integrator implementation in the H9000.
