Pony VCO is a fully analogue Thru-Zero oscillator with wavefolder and dedicated VCA in only 4HP. The module offers great stability and tuning capabilities thanks to its powerful core, based on Sound Semiconductors IC. It comes with a range selector, that allows it to go down to LFO range, as well as octave and waveform selectors. Pony VCO is also available in 1U format keeping the same functionality and control layout. Features Through Zero Frequency Modulation Wavefolding (Timbre) Pulsewidth Modulation (PWM) SYNC VCA LFO Specs Current Draw: +12v: 32 mA -12v: 25mA Width: 4HP Deepth: 30mm including power connector Aluminium, heat-treated front panel. Designed and assembled in Barcelona. In Through Zero oscillators, frequency is controlled by either positive and negative voltage. If FM CV goes below zero, the core will continue oscillating inverting its phase. This "little" change of behaviour allows the core to create a whole new range of timbres that are just impossible to achieve with regular VCOs. If you set the module as LFO, the range of funky modulations will be endless!
