The Con Brio ADS 200 can be considered one of those rare Holy Grail pieces of vintage synth technology. Released in 1980, the ADS (Advanced Digital Synthesizer) 200 was well ahead of its time - yet only two were reportedly made and at a price tag of $30,000 each! The ADS 200 followed up on the heels of the original ADS 100 of 1980 (only one made, never sold) which was a very large and high end analog synthesizer consisting of a dual manual splittable keyboard (microtonally tunable), programming interface, a separate TV monitor (for envelopes) and roll-around 'control cube' disk drive with computer hardware. The ADS 200 sought to become more commercially viable by combining the whole package into a single (but very big) all-in-one version. The original ADS 100 was most notably used for making some of Star Trek's motion picture sound effects.
