Dual Control

This module can interface two single-bus 1V/Oct keyboards.

The 1/4” TRS phone jacks connect to a single-bus keyboard or similar devices. Single-bus keyboards were common on the monophonic synths of the 1970s. They are designed to only detect a single key with either high or low key priority meaning the user can press multiple keys but only the highest (or lowest) key determines the pitch CV output.
