The Pa4X relies on KORG’s advanced EDS-X (Enhanced Definition Synthesis-eXpanded) sound engine, and comes complete with over 1,500* ready-to-play sounds. This realistic collection offers a vast gathering of classic and contemporary keyboards, band and orchestral instruments, plus electronic and acoustic instruments—from techno to folk. Included is a new multi-layer stereo grand piano (with damper and body resonance), plus electric pianos from the acclaimed KORG SV-1 Stage Piano. The digital drawbar organ includes key on/off noises, leakage, and Rotary Speaker emulation. In addition, the Pa4X has been equipped with new wind instruments, strings, basses—even acoustic and electric guitars. Sounds have been painstakingly captured using state-of-the-art methods that allow the finest of details to be accurately reproduced.
