Specifications

Overview

Three-channel algorithmic trigger generator, based on compressed representations of drum patterns and their variations. Most generated patterns will work best with channel 1 = BD, channel 2 = SD, channel 3 = HH or percussion, though variations are possible!

I/O and controls

  • Clock input.
  • Internal clock with a 40 to 240 BPM range (internal clock is paused when the tempo is set below 40 BPM).
  • Pattern reset trigger input.
  • Beat indicator/tap tempo button.
  • Latitude/Longitude knobs with CV input (range: 0 to 5V, protected).
  • Randomness knob with CV input (range: 0 to 5V, protected).
  • Pattern complexity/density knobs for channels 1, 2, 3 with CV inputs (range: 0 to 5V, protected).
  • 5V trigger and accent outputs for channels 1, 2, 3.
  • Secret 3-channel euclidean sequencer mode.

Settings / options

  • Clock resolution: 24ppqn, 8ppqn, 4ppqn.
  • The tap tempo button/beat LED can also be configured as a reset button/beginning of pattern LED.
  • 3-channel euclidean sequencer mode.
  • Alternative output layout with Clock/Reset outputs instead of Accent 2 and Accent 3.
  • Trigger or Gate output mode.

Unlockable items for DIY heroes

  • Bonus clock output!
  • Bonus random gate output!
  • MIDI interface responding to start/stop/clock messages!

Technical characteristics

  • All inputs: 100k impedance, DC to 500 Hz.
  • Clock resolution and MIDI processing latency: 120┬Ás (Worst case jitter < 0.5% at 120 BPM). Independent benchmark here.
  • Open-source hardware and firmware.
  • 16-HP.
  • Current consumption: +12V: 25mA ; -12V: 1mA.
