Isohélie – Triple 3-bit Posterizer (On order)

The Isohélie module offers three channels that are based around a 3-bit ADC/DAC. These will quantize the input signal into 8 equal steps, resulting in 8 different color shades. Processing a full RGB signal with the 3 channels will constrain it to 512 possible colors.

The bitswap feature allows to swap the 3 bits together before they’re summed by the R2R DAC, which results in a colorization effect and can be controlled up to video rate.

All 3 signal inputs and CV inputs are normalized.

Where does the name come from? Isohélie is a term used in french versions of graphic editing softwares to describe posterization, it is formed on ancient Greek “iso” meaning equal and “hêlios” meaning sun/light.
