ST Modular Kau'i Dual Techno Oscillator 8HP [DIY]

Awesome dual oscillator begging to be used for techno bass lines and leads. Has individual outs and a mix out along with wave shaping, a noise circuit, and Hz/oct pitch cv inputs. Gives you pure triangles and squares to funky hard edged waveshapes.

I built this unit from SMD pre-soldered PCB set, so I only had to solder the pots and jacks. I have a second one that I built from bare pcb which I'm keeping. Power header has a red mark to indicate -12v. Comes with a power cable.

Note about the in-rack picture, that's a hair from a dusting brush, not a scratch on the panel.

Dual Techno Oscillator

KAU'I is a basic two oscillator sound generator that was designed to create Techno basses and leads.

Oscillators A and B share identical designs but cover distinct pitch ranges. Using the A and B knobs located atop the module, you can seamlessly transition the waveform of each oscillator from a square-wave to a triangle wave. The SHAPE2 knobs then take this waveform and blend it with an independent sine-wave signal for each oscillator.

The LVL knobs adjust the volume of each sound generator, while rotating the NOISE knob introduces white noise to oscillator A on the MIX output.

Both oscillators feature a pitch control input accompanied by an attenuator.

This input follows a linear voltage-to-frequency response (Hz/Oct), making it ideal for generating unique Techno sequences at lower frequencies.

At the module's base, you'll discover a MIX OUT combining the outputs of both oscillators, alongside individual outputs for each oscillator.
