Similar to ‘Polivoks VCO II’ +-10V regulators for greater stability of operation, signal amplitudes adjusted to match requirements of contemporary modular synths – all output signals are also available simultaneously CV inputs redesigned to accept positive CV signals PWM circuit with manual and voltage controlled pulse width Sync input, so you can synchronise the Polivoks VCO to another VCO in your system.
