Instruo øchd

Eight analogue LFOs breathing life into any patch

4 HP Eurorack module

The Instruō øchd is a 100% analogue 8-LFO module in 4HP, designed in collaboration with Ben 'DivKid' Wilson. It provides eight free-running bipolar triangle wave LFOs spanning from audio-rate (up to 160Hz) down to glacial 25-minute cycles, all controlled by a single global rate knob. Its organic phase drift, self-patchable waveshaping, and track-and-hold capabilities make it an expressive, space-efficient source of living modulation.

Features

  • 8 free-running bipolar triangle waveform LFOs
  • Single global Rate knob controlling all LFO frequencies simultaneously
  • Bipolar Rate CV Input with attenuverter for CV scaling and inversion
  • LFO frequencies span from up to 160Hz (LFO 1 fastest, fully CW) to 25-minute cycles (LFO 8 slowest, fully CCW)
  • LFO 1 at center Rate knob position is set to vibrato rate between 3Hz and 7Hz
  • LFOs arranged fastest to slowest from top to bottom
  • Organic phase drift between LFOs due to 100% analogue design
  • Track and hold capability via negative CV at Rate CV Input
  • Self-patchable for feedback waveshaping of LFO waveforms
  • Bipolar LED indicator for each of the 8 LFOs
  • 10Vpp bipolar output range on all LFO outputs
  • Reverse polarity protection on power connector
