Our a line of Eurorack synthesizer modules are very affordable and include a re-triggerable ADSR  and a Sample & Hold module with Noise source and a dual VCO module.  Watch for a unique MIDI-CV interface coming later in 2018. 

Our modules use state-of-the-art components assembled using current surface-mount production techniques.  Classic analog designs are updated with new low-noise op-amps and cost effective components.  And prices are reduced by selling directly to the customer.
