MGB Hybrid Synthesizer





Controller Companion for an MG-1 Concertmate.

7 April 2007





Evolving from the desire to provide addendum circuitry for my MG-1, MGB is stand alone capable while providing control voltages for an attached MG-1 (or other analog synth).

The MG-1 embed's circuits controlable by external voltage control.   The intention to provide one single VCO, two complex ADSR's, and superior VCA, fell under the sword of my intention that this is the last analog synth i ever build for myself.

As such the desire to apply the best technology for this "final synth", propelled the design into a platform which is in many ways "homage" to the MG-1 while being interfaced to MIDI addressable digital convertors, bit map display, and motorized potentiometers.

There are three distinct, and sometimes loosly coupled components of the MG-B effort;
