The Variant Voltage Expander from Grayscale is an expansion module for the three permutation 18/12/6 modules from the same manufacturer. In contrast to a classic CV sequencer, Variant is more like a switched mixer with offset, which derives its voltages from the permanently generated "coincidences" of the main module. The generated CVs are output in parallel with positive and negative components. Two CV inputs with attenuators are available for further modulation.
