The instrument
Roland launched the first E series of intelligent synthesisers in 1987: E-20, E-5 and E-10 as well as the Pro-E Intelligent Arranger. A second series followed in 1991, including the E-35 and E-70, which utilise the LA linear arithmetic synthesis system. They offer high-quality sounds, drum patterns and backings, especially for the amateur keyboardist. The E-70 is the most advanced version of the E series.
