In order to decrease the differences between Mela 3 and Mela 4, I will be adding a new oscillator module called DS Oscillator. DS stands for Distortion Synthesis. The algorithm I will be using is the same as the "Phase Dist" oscillator in Mela 2-3 (and the NPD synth). There are different ways of looking at this algorithm and I think it's better to refer to it as Distortion Synthesis than Phase Distortion Synthesis.

I will probably be adding a classic Phase Distortion style oscillator as well later on.
