Grayscale Synapse Analog 4 Eurorack Module is a CV breakout module for the Elektron Analog Four and Analog Keys. The dual CV outputs of the A4/AK are connected to the 1/4" TRS inputs labeled CV:AB and CV:CD. These two inputs are split into four separate 3.5mm outputs. Each output has its own bicolor LED to indicate the polarity and intensity of outgoing CV signals (green is positive, red is negative).
The fully-analog circuit design ensures that CV signals will pass through unaffected, with no latency or voltage drop, so that the full +/- 10V output range of the Analog Four and Analog Keys can be utilized.
