Frequently Asked Questions

The external input accepts a DC voltage signal, typically from a photoresistor or photodiode; you’ll need to provide appropriate biasing circuitry for external sensors.
Yes, the dual CV outputs (positive and negative) allow you to split the signal and control two separate parameters, though signal strength may be reduced.
It's possible, but the response is relatively slow. It's better suited for broader light changes than quick gestures.
