description / manual

CV Expert (Cve) is a versatile dual-channel tool for customizing control voltages.


Its internal LFO is normalised to both inputs and allows you to choose between a triangle or square wave via a jumper on the back. The LFO connection is automatically interrupted when an external CV is inserted. Adjust the LFO rate with the LFO RATE potentiometer.


The signal received at the DC-coupled inputs IN ① and IN ② passes through three CV tools:


Polarizer

  • The PLRZR potentiometer enables voltage attenuation and inversion.

  • At the midpoint, the signal is eliminated.

  • Turning to the right allows the original voltage to pass through (as with an attenuator).

  • Turning to the left inverts the signal, e.g. positive signals are converted into negative signals.


Offset

  • Adds or subtracts voltage from/to the passing signal.

  • OFFSET control determines the offset range.

  • In the center position, there is no voltage offset. Turning the control to the right shifts the voltage to the positive range, while turning it to the left shifts it to the negative range.


Gain

  • Amplifies the signal with a maximum gain of 2 at the GAIN control's maximum position, effectively doubling the applied voltage (e.g., +1V becomes +2V, +3V becomes +6V, or +4V becomes +8V).

  • The voltage is capped at a maximum of +/-10V.
