Pic. 1 CuTeR functionality
HIGH and LOW levels are controlled with corresponding knobs. Also CV inputs are available to modulate HIGH and LOW levels. CV knobs vary amount of modulation.
Adds values from seven channels. If no input is connected - channel outputs constant voltage. Zero by default, knob regulates it up to 1. If input is connected - knob regulates input volume. Switch regulates sign of addition. Light toggle is channel mute. Bottom light toggle is mute for all channels. Based on A-185-2 Precision CV Adder.
