JH Wave multiplier

This module contains two different waveshaper circuits that are inspired by the famous Serge wave multiplier. The circuits were developed by Jürgen Haible. You can read all about the circuits on his homepage.
To both circuits I have added VCAs at the inputs. It is important to be able to control the amplitude of the input signal dynamically, as the amplitude affects the waveform  totally.
On circuit A, which is based on JH Shaper A, I have also added a VCA to introduce feedback in the circuit. Feedback mainly causes the sound to get brighter.
Circuit B, which is based on JH Shaper B, has a VCA to replace the potentiometer in JHs circuit. This is the "Shape" parameter on my module.
A three way toggle switch enables me to quickly switch between series and parallel coupling of the two circuits. They can of course be used separately too.
The soundeffects obtainable from this module can be dramatic, especially if both sections are connected in series. It can also sound surprisingly similar to a resonant VCF.

Oakley Wavefolder

This module is based on a circuit board from Oakley Sound Systems. You can read all about the circuit on their homepage.
I just added some circuitry to make modulation controls bipolar. I also added my signal indicator circuit.
The sound from this module is considerably more subtle that from the Wave multiplier. The Wavefolder is maybe most useful for processong control voltages.

The large green circuit board is the Wavefolder board from Oakley.
