The Lyricon Company Euro-Rack Module. We also design and manufacture accessories, including a Euro-Rack Lyricon interface module that works with the Lyricon II and Driver controllers (horns). This module provides a sub-set of the Control Voltages produced by a Wind Driver Console, and so removes the need for the actual console (the case); great for touring! This module would typically be installed in a Euro-Rack modular synthesizer, along with the minimum of a VCA module and a VCO module, of which there are dozens of each to choose from.
The Lyricon Euro-Rack Module is available for $380.00 plus shipping.
