-An other voltage controlled oscillator. It comes with a really ​beautifull ​shaped ​sinewave ​stabel ​and with the same peak to peak over all frequencies. One can switch between square, triangle and sine wave. In the square/​triangle mode one can change with a potentiometer from triangle to sawtooth wave or change the duty cycle of the square wave. In sine wave mode one can shape the sine wave to an interesting "sea saw" wave.\\ +This is the main voltage controlled oscillator ​due to its really ​beautiful ​shaped ​sine wave it is stable ​and with the same peak to peak over all frequencies.

-All OpAmps are the rail to rail [[http://​ww1.microchip.com/​downloads/​en/​DeviceDoc/​21733j.pdf|MCP6002]] ICs.
