Three Channel Chaotic CV Generator

The GBU-12 Paveway II is an 8HP chaotic CV generator in Eurorack format. There are 3 individual channels with two CV outputs per channel (X and Y) as well as 3 x gate outputs and a CV input per channel. Each channel will send a gate whenever output X is higher in voltage than output Y. There is also a knob for each channel to influence the chaotic waveform – with the turned up full, the chaos will become slightly faster and somewhat wilder. The channels do not influence each other, unless you self patch them!

The GBU-12 CV inputs are highly sensitive to incoming CV and can receive pretty much anything: gates, triggers, LFO’s, envelopes, clocks and audio. The chaos circuitry of the GBU-12 is considered a “jerk” circuit, which means that it often starts with a more sudden “pull” that then evens out. It’s a bit wilder than the chaotic circuits used in most other modules.

The chaotic gate output is really useful for triggering other envelopes on a semi regular basis, especially when timing is not essential and you want diversity and life in your patch. Use it to reset an LFO, to ping a filter or Lowpass-gate or to trigger drums or other “events” in your patch.
