A polyphonic version of the Dual VCA and Inverted module, a small module that hosts two simple voltage controlled amplifiers (for control voltages or audio signals) and a voltage inverter.
The inverter be used to take voltages between 0V and 5V and inverts this so that 0V becomes 5V and 5V becomes 0V, or as a traditional inverter around 0V or around any specific voltage between -5V and +5V. This is useful with envelopes to do interesting things to audio signals or other control voltages.
The dual independent VCAs can be switched between linear and exponential modes (useful for audio sources), can allow inversion for negative CVs or have negative CV values meaning 0V, and have optional Zero Crossing sensing to help reduce clicks when using switching or agressive envelopes.
