Description

  

Designed in collaboration with 

Ben “DivKid” Wilson

, the Instruō 

øchd 

packs 8 all analogue LFO’s into a convenient 4HP package. Each 
independent core is free running with rates configured from fastest to 
slowest arranged from top to bottom. Each frequency range was tuned 
by ear during development to give the optimum spread of control 
frequencies running in parallel. Being 100% analogue, the LFO’s will 
phase organically with the ability to ebb and flow together with their 
global frequency control.

Modulation breathes life into otherwise static patches, but CV sources 
can often run out quickly, even in larger systems. 

øchd

 adds a lot of 

movement without hogging a lot of space. Both small lunch box cases 
and larger set ups can be made to drift, move, and organically change 
over time. With either subtle use of

 øchd 

to keep things alive or wider 

ranging use that drives a whole patch that drifts around itself.

Features

•  8 free-running bipolar triangle waveform LFOs
•  Single rate control with CV input and attenuverter
•  Track and hold/LFO stalling capabilities with negative CV
•  Self-patchable for unique waveshaping possibilities
•  Fastest LFO can go up to 160Hz without external CV
•  Slowest LFO can go down to a 25 minute cycle without external CV
•  Bipolar LED for each LFO
•  100% analogue
