The instrument
The Pro-E Intelligent Arranger belongs to the first series of e-synthesisers that Roland introduced in 1987 with the E-20, E-5 and E-10. The instruments use the LA linear arithmetic synthesis system. They offered high-quality sounds, drum patterns and backings for the amateur keyboard player. The E-5 and E-10 were scaled-down versions. The improved E-30 came onto the market in 1990. The RA-50 Realtime Arranger is a modular version.
