Frequency Central took the versatile Roland System 100M VCO design and modified it for eurorack while adding some extra features. The design is also modified to avoid any expensive or hard to find rare parts. The VCO outputs saw, square and triangle waves, and there is pulse width modulation on the square wave from an even square to a 90% duty cycle pulse wave. There is a sync input with "weak" and "strong" sync types.
This VCO has a huge range from a cycle every minute and twenty seconds all the way up to 100,000kHz. It is still easy to control though since there are seprate coarse and fine knobs for frequency. It is 1v/octave accurate for 7 octaves. In addition to a 1v/octave input there is a CV input with an attenuator for FM.
