Description

Rorschach is an analog-style desktop video synthesizer designed for artists exploring video synthesis, live visuals, and audio-reactive image generation. It works equally well as an entry point into video synth hardware or as a creative expansion for experienced users.

Rorschach is well suited to live performance, with the ability to self-generate evolving patterns using its built-in randomisation features. Its functionality can be extended further by feeding control voltage, gate signals, or audio into the modulation inputs, making it easy to integrate into modular and experimental setups.

With a clear, functional, and immediate control layout, Rorschach is an excellent starting point for anyone taking their first steps into video synthesis, while still offering enough depth to remain engaging for more experienced users. Compact and portable, it also features an audio output that converts the video signal into a distinctive drone voice.

Rorschach generates its own black and white composite video patterns straight out of the box. Its functionality expands further when used alongside modular or Eurorack systems, or when audio signals or control voltage are fed into the CV and gate inputs. The focus is on experimentation, play, and hands-on control.

A dedicated random section allows the synthesizer to run freely, generating evolving patterns automatically and in real time. Leave it running during a performance, or introduce external signals such as a kick drum or sequencer to push the visuals into new territory.

• Form control selects from six pattern generator modes
  – Can also be modulated via audio input or control voltage
• Random control sets the amount of randomness applied to the four position parameters on each refresh
  – Independent switches and gate inputs for each random parameter
  – CV input for random amount (0-5v anything above this clipped to 0-5v)
• Clear screen modes:
  – Clear / Random Clear / No Clear
  – Gate input for clear screen
• Pattern colour switching:
  – White / Black / Invert
• Horizontal and vertical mirroring switches
  – Independent gate input for each axis
• Composite video output via RCA connector
• Audio output allowing the generated visuals to be used as a drone sound source
• Power Rorschach is supplied with a 9V battery clip.
  If you would like to run Rorschach off a wall adapter you will need a 9V CENTRE POSITIVE adapter (not included)
