Roland E-20 Intelligent Synthesizer / Arranger (100 V version, includes original case) 61-key velocity keyboard with built-in arranger features (auto accompaniments, backing tracks, style memory). Uses Roland’s LA synthesis engine with onboard effects (digital reverb, chorus). MIDI In/Out/Thru. Complete with original hard or soft case. This is a 100 V (Japan model) version — for use in Australia you'll need a reliable 240 → 100 V step-down transformer unless converted internally.
