If I do this:
; 1 cycle
set feedback = 1.01
play fmfb(hz-to-step(1.0), feedback, 1.0)
...there is a "bump" in the middle of the wave, which when zoomed in, appears to be "ringing" at 1/2 of *sound-srate*, that is, sample x is too high, sample x+1 is too low, sample x+2 is too high, sample x+3 is too low, etc. no matter what *sound-srate* has been set to.
This distortion is present in small amounts all throughout the wave, even with low values for feedback index. You just have to zoom in close enough to see it.
Am I doing something wrong, or is this a bug in fmfb? I've tried various sample and control rates, even rebuilding *sine-table*, which fmfb does not appear to use.
