wavemix-tonality len amplitude rnd-init min max tonality
Adds a random sine wave from range min..max of len to each tonality with amplitude. Makes symmetric changes to the tonality.

Or non-symmetric, if a non-equal length is used. This makes the modulation waves to be scattered over tonalities which leads to non-symmetric distortions.
