hubris devices


Goliath is a dual-monosynth drone machine designed to make rumbley-rumbles and complex drones, either standalone or as the background to a larger composition. It’s intentionally bare bones, and has only those features it absolutely needs to be a playable instrument. More recent models also include a built-in saturation circuit lets you bring out the overtones and beat frequencies created by the interacting tones.

It works by sloshing together and filtering the outputs of two tunable, square-wave oscillators. The “lower” voice has a tunable range between about 13-15Hz, and the “upper” voice has 6 or 12 (again, depending on the model) different frequency ranges which are bigger or smaller depending on where you are in the spectrum. When combined, the two voices interact, and the result is positive and negative interference that produce beat frequencies / weird rhythms at the lowest ranges, and strange harmonics and overtones in the upper ranges.

When it’s on it’s on, so if you have the volume up, it will go until you turn it off. I accidentally left an early prototype on for 3 days over a long weekend, and it sat contentedly in the corner the whole time humming quietly to itself.

Janus is a two-voiced multi-mono synth. The simplest, and yet most stimulating of the Hubris modules, it has two voices with different ranges which interact via a switching transistor. In effect, one of the voices acts as a ring-modulator for the other. This creates a semi-controlled interaction of two mis-matching signals.

The sounds that these two oscillators produce are surprisingly complex and evocative. Singing harmonies, rumbling dissonances, screaming inharmonics, and whispering negative phase. You can sit for hours just tuning the two voices against one another and never get bored.

Power: +9v DC
Output: Unbalanced Mono 1/4-inch


Hydra is a multi-mono synth, with multiple voices and pseudo-but-not-really-stereo output. Each voice is independently tunable within its own frequency range. Each also has its own volume control, and can be assigned to any of the outputs, but only ever one output at a time. Every output also has its own volume control so that each group of voices can be faded in and out to taste.

This basic model has 4 voices that can be assigned to 2 independent outputs, with ranges corresponding rougly to the traditional 4 bands of low, mid, high-mid, and high. However, the number of voices can be expanded or contracted as you like, with the frequency spectrum divided across them.

Independently assignable outputs allow you to “pool” your voices and control which voice interacts with which. Multiple outputs is also optimal for people who work with multi-speaker, expanded-stereo, and 5.1 setups.

Power: +9v DC
Output: Unbalanced Mono 1/4-inch


Medusa is a triple-mono drone machine that produces odd and unearthly harmonies and sounds by turns scary or sweet, haunting or friendly. The pitches of the 4 voices are set by offset knobs and controlled by a master pitch control. So, the fourvoices are independently variable, but can all be moved at the same time with a single knob.

Because the individual knobs set a relative interval between the voices, as you sweep the master control they go in and out of harmony with each other, depending on the ratio of the voltages between each frequency and the master control. Every part of the system interacts with each other making it unpredictable on the one hand, and very intuitive on the the other.

The pitch of each voice is controlled by a semi-enclosed LED-LDR pair, so that the baseline for the unit’s pitches depends on the amount of ambient light in the room. This has the added bonus of allowing it to be played as a kind of light-theremin, either by using your hands to cast shadows, or by shining a flashlight onto the pitch controller.
