A*B+C v4

Voltage-Controlled Voltage Processor

AxB+C is the ultimate utility for audio and control voltage. It performs multiplication, addition, and attenuation, providing a simple way to create complex signal interactions and timbres.

It is formed by two channels, each of which takes two input signals (A and B), multiplies them (A × B), and then adds a third signal (C) to the result.It is formed by two channels, each of which takes two input signals (A and B), multiplies them (A × B), and then adds a third signal (C) to the result.
