Blokañ is a ring modulator for Eurorack based on tubes and transformers. It is built like a classic diode ring modulator, but the diodes are tube based.

The built-in VCO provides the carrier signal (saw wave) and can also be tapped using a dedicated output. The VCO provides a voltage control input. The carrier signal can also be replaced by an external signal.

The module sounds different from conventional ring modulators due to the tubes. There may be slight noise and the carrier wave may crosstalk in the output.
