Ensoniq was founded in the early '80s by some engineers from Commodore. Ensoniq's first product, a software drum machine, was aimed at the home computer market. One of Ensoniq's co founders, was responsible for designing the Commodore 64's three-voice synth chip. In 1982 he designed a portion of a PC that was similar to the sound synthesizer that ended up in the Amiga. It was this chip, the 'Q chip', that was used in the Mirage, the world's first affordable sampler and the ESQ-1, Ensoniq's wavetable synthesizer. Later came the MR and ZR workstations. The Ensoniq ZR SoundFont is a collection of multiple instruments that were included with the ZR76 keyboard. Ensoniq sound designers used the content that had been collected for the samplers. Special note - A Kawai 9ft Grand has been substituted for the Perfect Piano due to license restrictions.
