The Eurorack Palette brings our Colour format to the modular synth world. 

Controls and I/O

CV Bias and VCA CV Inputs: Set the initial level for each of the three VCAs. These levels are increased by positive (unipolar) voltage at the corresponding VCA CV Input jack, typically from an envelope generator. The VCA level may influence the effect of installed Colours or ColourCV’s.

VCA Inputs and Outputs: For each channel, signals pass through a VCA before being processed by an installed Colour module. The three channels can also be normalled in series or in parallel, with input 1 normalled to input 2 and 3 (behavior selectable via internal switch).

Colour Control and Colour CV Inputs: Allows control over specific parameters on installed ColourCV modules. This control level is modified by negative or positive (bipolar) voltage at the corresponding CV input jack, typically from an LFO or Sequencer.

Summed Output: Provides a single output with the outputs of the three VCA’s mixed together. Patching a VCA output may remove it from the SUM output (behavior selectable via internal switch).

Real analog plugins.

Colour is a new format for analog audio gear designed for and by the DIY community. We took our favorite sounding analog circuits and put them on modules that are small, affordable, and swappable.

The Colour format consists of Colours and Palettes:

Colours are ultra-compact, pluggable analog circuit blocks that impart various types of analog color. Check out our ever-growing selection of Colours. Colours can be designed and released by anyone.

Palettes provide controls, power, and support circuitry for Colours. We currently offer the Colour 500 Palette and CP5 Mic Preamp with Colour.
