Ruckus

Ruckus is a trigger sequencer using summed clock dividers as a novel way of sequencing modules.

The module is driven by a clock signal in the CLOCK input. The internal clock is reset by a trigger on the RESET input.

Clock dividers are arranged in a 4 by 4 grid. The division is controlled by the large knob and the division displayed at the bottom of the module. Each column and row of the grid is summed and the resulting sequence of triggers is output in the port at the end of the row or column.

The two smaller knobs to the lower left and right are the Beat Shift and Probability controls respectively. The Beat Shift control moves the trigger backwards or forwards in time with respect to the master clock. The Probability control controls the probability that the clock divider will emit a trigger when expected.

Polyphonic CV input for Division, Probability and Offset are summed with the control; the channels are assigned left-to-right then top-to-botton; the top left controls are mapped to polyphonic channel 1, top-right to channel 4 and so on.

Buttons at the end of each row and column mute the respective output port.

Ruckus is inspired by the excellent Trigger Riot by Tiptop Audio which goes far beyond what Ruckus does. Mylar Melodies has a great video which demonstrates the potential of summed clock dividers https://www.youtube.com/watch?v=AjKLewx17iQ
