Dual Channel Burst Generator, with Integrated LFO and Clock Divider

Variatic Erumption is a dual-burst generator. When triggered, it produces a controllable sequence of gates synchronized to a LFO. A 1v/8va LFO is included, and has its own dedicated output. Fans of this module include Aaron Funk of Venetian Snares.

LFO Section:

  • Any external LFO/clock may optionally be used. Bursts can be terminated early with the choke. Burst length can be controlled as well as the pattern used for the burst.
  • Int/Ext – This switch selects the burst clock source between the internal LFO or an external clock.
  • In – Jack 0-8v – In internal LFO mode this jack is a 1v/8va CV for the internal LFO and has 8 octaves of range. In external mode, it is a clock input.
  • Tmp/Div – Knob – In internal LFO mode, this knob controls the LFO tempo. It allows 4 octaves of control. In external mode, it is a controllable clock divider with 1-32 divisions.
  • Fst/Slw – Toggle – This switch controls the base tempo of the internal LFO.
  • Out – Jack – This jack outputs the LFO used for burst generation.

Burst Sections:

  • Hit (Jack) – This gate input will start the burst on a rising edge. If using internal clock mode, it will also reset the phase of the internal LFO to match the HIT phase.
  • Hit (Switch) – This tactile switch will start the burst when depressed. If using internal clock mode it will also reset the phase of the internal LFO to match the HIT phase.
  • Chk (Jack) – This gate input will terminate the current burst on a rising edge.
  • Chk (Switch) – This tactile switch will terminate the current burst when depressed.
  • Cnt (Jack) – This jack allows to control the burst count with a control voltage.
  • Cnt (Knob) – This knob allows the control of the burst count. It acts as a scalar when using an external CV.
  • Out (Jack) – This gate output sends a burst based on the clock when triggered with a Hit. There is an orange LED to indicate the current output state.
  • End (Jack) – This gate output sends a pulse based on the clock at the next clock following the end of a burst.
  • Pat (Jack) – This jack allows CV control over the pattern.
  • Pat (Knob) – This knob controls the current pattern used for the burst. Built-in patterns are documented in detail on the following page. When rotated fully CW this knob will double the maximal length of the pattern to 64 gates. When in double length mode the bust pattern is the same as when fully CCW (every clock outputs a gate).
