Four Channel Control Voltage to MIDI CC

This is a very simple four channel control voltage to MIDI CC converter. This device scales positive voltages, then limits positive and negative voltages, before being converted to a digital value and sent as a USB MIDI continuous controller message. Note that negative voltages are simply clipped.

This data can then be used to map control voltage signals to digital software.

In the example video, four control voltages from an LFO, an ADSR and two channels of Maths are converted to MIDI CC messages and mapped to parameters in Lumen.
