GT2

1U Dual Gate-to-Trigger converter. Given a gate at an input, it will spit out a very brief trigger voltage from the relevant output. The first input is normalised to the second, meaning that a gate at the left input (and nothing connected at the right) will emit a trigger from both left and right outputs.

GT2 is based on a design by Ken Stone; see Credit for detail.

Usage ideas

  • Turn a long gate from a sequencer, MIDI converter, or other note source into a short pulse, ideal for plucking Low Pass Gates or striking other percussive sound sources.
  • Note that you’ll need a hard-edge signal to trigger the GT2: a gate, or square-wave oscillator/LFO should work, but a triangle wave or sine wave is unlikely to be able to trigger it.
