Oscillator waveshaper aka "enhancer"

[jpcima]

There exists an "enhance" setting which permits to set a bias prior to a clipping diode circuit.
It will allow to pass a part of the negative signal from the output of the "differentiated square" oscillator.

It's in branch waveshaper but it's not as enjoyable, it sounds too clean.

Next it's needed to review the shape of oscillators according to the ARP OMNI document.
