 ## The Harmonics shifter
 
-The main characteristic of this oscillator is that you can shift the harmonics' distribution on the frequency axis by the shape parameter. It is done by shortening the time of playing a single waveform while keeping the interval between each single waveform playback starts. The shorter the interval, the higher the frequency of the harmonics. You may compare it to the pulse-width modulation of pulse wave oscillators.

 Moreover, Waves2 plays a single waveform as many as possible in one wavelength. It makes the sound much brighter than playing the waveform only once. To let the sound keeping its original pitch, Waves2 decreases little by little the amplitude of each waveform playbacks in the same cycle.

-Some waveforms produce too much harmonics when it comes to Waves2. You can make the harmonics distribution more gently by decreasing the amount of amplitude of repeated waveform playback with the shift-shape parameter.
