The sophisticated 88-note A-90 keyboard offers the unsurpassed Roland PA-4 piano feel with channel aftertouch and a comprehensive collection of master controller functions. By adding the VE-RD1 Piano Expansion Board, the A-90 is transformed into the A-90EX, a 64-voice digital piano/synthesizer with 128 tones, true stereo piano samples and built-in effects. Four independent MIDI Outs, 20 assignable controllers, large buttons derived from the JD-800 and patch names for virtually all Roland sound modules and SR-JV80 Series expansion boards make the A-90/A-90EX powerful yet very user friendly.
