ADDAC System ADDAC405 VC Relabi Generator
A Eurorack module combining a complex CV generator with quad threshold gate outputs, part of the ADDAC400 Series.
Overview
The ADDAC405 VC Relabi Generator is a Eurorack module designed by ADDAC System as part of their ADDAC400 Series. It functions as both a gate/trigger generator and a complex modulation source, capable of producing a unique "Relabi Wave" through internal LFOs or external CV input. The module compares this waveform to two thresholds, generating four gate outputs—two for the upper threshold and two for the lower—with a single knob controlling the length of all gates. A dedicated CV input allows voltage control over gate timing, adding flexibility in modular patching.

Design
The module generates a complex waveform ("Relabi Wave") that is compared to two adjustable thresholds, producing four gate outputs—labeled 1&2 for the top threshold and 3&4 for the bottom. A single potentiometer sets the gate length for all four outputs, and a CV input allows external control over this parameter. Users can bypass the internal LFOs entirely by feeding an external CV or LFO signal into the modulation path, and the mixed LFO output is available as a modulation source.
Market
The ADDAC405 VC Relabi Generator had an original price of 265€ (approximately $410.75 USD). Current listings vary, with one Australian retailer pricing it at $539.00 AUD. Production was limited, with forum reports indicating fewer than 150 units made. Warranty extensions were available through retailers, with options for 1, 2, or 3 years of coverage. User feedback includes strong endorsement, with one stating, "I'd 100% recommend it," while others noted its complexity requires careful study of the user guide.
