The Quadrasynth was the first synthesizer produced by Alesis and is named for the synthesis engine, which allows up to four 16-bit PCM waveforms to be combined into a single sound. Although it has 64 notes of polyphony, it should be thought of as 64 "tones" of polyphony, since using multiple waveforms in a patch reduces polyphony by a corresponding amount (with 4-tone patches having 16 notes of polyphony). Its 16MB ROM could be increased another 4MB or 8MB with PCMCIA expansion Q Cards. It was also the first synthesizer to offer the ADAT digital optical interface.
