Con Brio | ADS 100


Originally designed as a tone generator to test hearing, the ADS was innovative in its approach to synthesis, and was one of the earliest digital synthesizers. It was capable of several types of synthesis, including additive synthesis, phase modulation synthesis, and frequency modulation synthesis (commonly abbreviated to FM).

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 original ADS 100 was most notably used for making some of Star Trek's motion picture sound effects.

It used three 6502 processors (the same processor used in the Apple II computer and Commodore 64) and included a video monitor which displayed sequences and envelope parameters. It could also be upgraded with commonly available computer peripherals, including an 8-inch floppy disk drive. All of this was controlled via a brightly colored control panel and two 61-note keyboards.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
