I created a VCO which outputs a full-wave rectified sine wave signal. It looks (and sounds) a bit like the sine wave output of Oscillator 1 on the EMS Synthi range, when you alter the waveshape. Here are some example waveshapes and spectrum plots of the signals you can generate using this patch:
The sound has quite a muted, vintage, 'wooden' feel to it. Not as bright as a sawtooth, and not as hollow as a triangle.

The patch uses only modules from VM Nucleus and the Dome Music Technologies Freebie Collection.

Short YouTube Demo of the patch.

Here's an even simpler patch which ring-modulates the sine wave and pulse wave outputs of a single stock Oscillator module. It has the same mellow sound as the previous patch when the pulse width is at exactly 50%. It gets buzzier more quickly when you change the pulse width, becoming most extreme at around 25%.
