When Kurzweil released the PC3K in 2006, they weren't just updating their workstation line—they were consolidating two decades of synthesis expertise into a single, uncompromising machine. The PC3K represents the culmination of everything the legendary K-series and PC-series had learned, then pushed further with a synthesis engine that remains remarkably deep even by today's standards.
At its core sits the Dynamic V.A.S.T. synthesis architecture, capable of 128 voices with up to 32 layers per program, giving you the flexibility to build extraordinarily complex and detailed sounds. The engine combines virtual analog oscillators with sample-based synthesis, drawing from over 900 factory presets that span everything from meticulously sampled grand pianos and vintage keyboard emulations to lush orchestral sections and experimental synthetic textures. The 64 MB of ROM sounds include Kurzweil's famous orchestral and contemporary sound blocks, plus the Stereo Triple Strike Piano and Classic Keys for those seeking authentic vintage electric piano character.
The control surface is where the PC3K truly shines for hands-on performance. You get 88 fully weighted hammer-action keys with velocity and monophonic aftertouch sensitivity, a pitch wheel, modulation wheel, nine front-panel sliders that double as drawbar controllers, ten programmable switches, and comprehensive pedal inputs for expression, sustain, and footswitches. This level of tactile control means you're never fighting the interface to shape your sound in real time. The effects section delivers over 500 processing options—reverbs, delays, chorus, flange, phaser, EQ, distortion, Leslie simulators, and compressors—distributed across 16 insert effects over 11 buses, plus a dedicated master effects section with global EQ and compression.
The PC3K comes in three keyboard sizes: the PC3K8 with 88 keys, the PC3K7 with 76 keys, and the PC3K6 with 61 keys, each weighing between 14 and 24.5 kilograms depending on the model. All versions include 128 MB of nonvolatile sample flash RAM for your own recordings, USB connectivity for data storage and OS updates, and MIDI I/O for integration into larger rigs. The sequencer and 16 independent arpeggiators round out a feature set designed for both studio composition and live performance.
Since its release, the PC3K has maintained a devoted following among professionals and serious hobbyists who appreciate its sound quality, synthesis depth, and rock-solid build. While newer workstations have emerged, the PC3K's combination of authentic instrument emulations and powerful synthesis architecture has aged gracefully, making used units still highly sought after by musicians who value hands-on control and sonic character over cutting-edge interface design.
