Using a simple trigger input, you can round-robin your signal through, 2, 3 or 4 outputs with the Doepfer A-151 Quad Sequential Switch

  • Switch module for Eurorack systems
  • Use a trigger input to send a signal to 2, 3 or 4 outputs
  • Reset to output 1 with a further trigger input
  • Width: 4HP
  • Current draw: 40 mA

The Doepfer A-151 Quad Sequential Switch is like an electronic four-position rotary switch.

The A-151 includes trigger and reset inputs, four in / outputs, and a common out / input. Each time a pulse is received at the trigger input socket, the common out / input is connected to the next in / output. After the fourth in / output, the next trigger makes it step back to the first again, and so on.

A positive pulse at the reset input switches the out / input immediately back to the first in / output (see Fig. 1). Voltages in the range -12V...+12V at the O/I resp. I/O sockets can be processed by the module.

Four LEDs indicate the active in / output (ie. the on that is connected to the out / input at any particular time). A toggle switch allows the number of steps to be switched between 2, 3 or 4
