The Roland E20 was introduced in 1988. Described as an intelligent synthesizer it was the 1st product of Roland SPA which had been set up after a takeover of the SIEL company in 1987. It was a venture to enter the home keyboard market dominated by casio and yamaha. Featuring styles and built in speakers, the E20 used the advanced LA Synthesis system of the D50 as its core sound engine. The E20 set a new standard with high quality sounds and styles which was a jump ahead of Yamahas competing PSR line. As well as the E20, the cheaper E5 and E10 were subsequently launched as cut down versions while the enhanced E30 debuted in 1990.
