The series of rect access to all parameters in a one-knob- harmonics can be squeezed or spread apart, per-function arrangement.
  • Page 3 At the maximum posi- tion, the amplitude spectrum is very flat (if no soidal partials generated by Odessa adhere to a harmonic pattern wherein frequencies are additional comb response is engaged), which strictly integer multiples of the fundamental results in a buzzy, narrow pulse waveform.
