Rebel Technology Clk is a clock module for modular synthesizers in Eurorack format. It has three clock generators, which output three synchronized clock pulses. It consists of a master clock and two double function multipliers/dividers. The uppermost potentiometer gives the master clock which can be between 40 and 200 bpm. If the potentiometers are rotated clockwise, the module multiplies the signal counterclockwise and divides the clock signal. The further you turn the potentiometer, the greater the value is divided by or multiplied by. The three outputs are always perfectly synchronized.
The center and lower controls multiply or divide the master clock depending on whether the knob is rotated clockwise (multiplication) or counterclockwise (division) from the center position. In the middle position they output the same clock as the master, they multiply / divide by 1.
