Arcadian Rhythms is an arcade button module that can be used to trigger drums, envelopes and other events in a Eurorack system. When the buttons are pressed, they light up and send a gate. As long as a button is held down, the gate remains high. The brightness between colors will vary slightly, but the trimmers on the back of the module will adjust the LED brightness so the three buttons match. Reducing the brightness will also reduce the current draw (each button draws 41mA at full brightness).Choose red, blue, green, yellow or white buttons. Specifications: - Module depth: 35mm - Module width: 6HP - Current draw: +12V: 123mA max (41mA per button)
