Sleepy CircuitsHypno Core Eurorack Video Synthesizer

Sleepy Circuits Hypno Core

Dive into your video dreams with Hypno from Sleep Circuits, a digital video synthesizer perfect for adding visuals to your Eurorack system. Inspired by analog video synthesizers, Hypno shrinks down what would otherwise take a whole system down into a compact form factor.

At Hypno's core lie two oscillators mirrored on either side, each with selectable frequency, shape, rotation, and polarization. These are the primary shape generating tools, which can be further altered with the center controls. The gain control in the middle sets the overall amplitude of the video oscillators, with black in the middle and either positive or negative gain when turned to the left or right.

When turned past the midpoint on either side, the frame begins to feedback on itself with five feedback modes selected by the button. Shapes can have fractals applied to them, with adjustable amount and angle, creating more complex shapes out of the basic oscillators. Oscillators and the feedback path can be routed into each other for advanced modulation functions. Three presets can be saved and loaded on the fly to quickly change the available patterns. Each of the parameters can be further controlled via CV with a range of -5V to +5V found on audio Eurorack modules, as opposed to the -1 to +1V range found on the LZX line of video synthesizers. Hypno also accepts MIDI signals via the USB connection on the panel to control its parameters.

Hypno is a great way to bring video synthesis to your Eurorack setup in a compact package that interfaces easily with audio modules, offer hours of exploration and expedition into the weird world of video synthesis.
