KeyboardDigitalPolyphonic

Back in 1998, this synth arrived as a bold step forward for workstations, blending multiple synthesis engines into one powerhouse that felt like the future of sound design—especially with its rare mix of sampling and physical modeling in a 61-key package.

Its Extended Synthesis system combines AWM2 for realistic samples, AN for analog-style modeling, and FDSP for dynamic, note-responsive effects that make sounds feel alive and organic, all structured around a four-element voice architecture for layered complexity. You get 64-note polyphony, a 16-track sequencer with 30,000-note memory, a four-track arpeggiator with 50 patterns, and robust effects including reverb, chorus, and 79 insertion types like distortion, overdrive, and auto-wah. The panel sports smooth, weighty round knobs, a pitch bend wheel, modulation wheel, and dedicated controls for real-time tweaks, all on a sturdy 1061 x 407 x 129mm frame weighing 15kg with curved end panels that give it a distinctive, grippable presence despite the bulk. It holds 512 voices (256 preset + 256 user) and 128 performance setups, with 1 stereo out, MIDI I/O, and channel aftertouch on the velocity-sensitive keys.

Players have long praised its versatile, pro-grade sounds that hold up in modern mixes, though some note its heft and learning curve for the deep editing as classic trade-offs for that era's depth.
