2CK

Intertwined Dual Clock Source

overview video | user maual | shop

2CK is an intertwined dual clock source. Two identical voltage-controllable low frequency squarewave generator units are fit into a 4HP panel - Clock A and Clock B. The frequency of each generator is determined by a manual initial frequency control (big knob) and the CV input with the associated attenuverter (small knob). Controls for Clock A are yellow, and controls for Clock B are blue, for easier navigation.

When the CV input jacks are not used, each has other half's internally used triangle wave output normalled to it, resulting in the two clock generators affecting each other in a non-binary chaotic manner. This makes the module instantly generate curious patterns without any external gear.

The clock pulse outputs (0-10v) can be used not only as clock signals (e.g. for a sequencer) and other logic signal needs, but also as bipolar squarewave LFOs and even bass-range audio VCOs, as the clock cycle time ranges from 30 seconds (0.3hz) to 0.007 of a second (140Hz). Both halves track CV exponentially, and it's possible to tune it very close to a good 1 volt per octave with the built in attenuverter.
