CLK is a 4HP triple clock generator that outputs three synchronised clocks. It comprises of a master clock and two dual function multiplier/dividers. Turn clockwise to multiply, anti-clockwise to divide. The outputs are always perfectly synchronised. Use it to feed several trigger sequencers or to generate instant ‘four on the floor’ style patterns.
The top knob sets the master clock, ranging from 40 to 200 BPM. The top jack outputs the master clock as 16th notes.
The middle and bottom knobs either multiply or divide the master clock, depending on whether the knob is turned clockwise (multiplication) or anti-clockwise (division) from the centre position. At 12 o’clock they output the same clock as the master, that is to say they multiply / divide by 1.
The middle knob values are 1 in the centre, then 2, 3, 4, 6, or 8 times as you move away from 12 o’clock.
The bottom knob outputs 1, 2, 4, 8, 12 or 24 times multiplication or division.
