K2700 88-Key Synthesizer Workstation

Built as a flagship continuation of Kurzweil's K-series lineage, this workstation is designed for players who want deep synthesis and stage-ready control in one instrument. The weighted 88-key Italian hammer action with polyphonic aftertouch gives it the feel of a premium performance piano while still behaving like a programmable synth hub.

Under the hood, 256 voices of V.A.S.T. are joined by FM, virtual analog, and sample-based engines, with FlashPlay streaming that keeps the massive 4.5GB factory library instantly accessible and leaves 3.5GB for user content. You can run up to 16 zones for splits, layers, and external MIDI control, then shape parts with multimode filtering, modulation routing, 16 arpeggiators, and a 16-track sequencer. The hardware panel includes pads, a ribbon controller, sliders, knobs, and dedicated controls for fast hands-on editing, while the effects section covers essentials from reverb and delay to compression and EQ. Connectivity is studio-friendly too, with USB audio, full DIN MIDI I/O/Thru, dual XLR/TRS combo inputs with phantom power, and four balanced TRS outputs.

Players tend to praise its sound set depth, keybed feel, and sheer flexibility for both live rigs and composition work, especially if they need one keyboard to cover piano, synth, and controller duties. The tradeoff is complexity: it rewards time spent learning the architecture, but once dialed in it can function as a complete centerpiece instrument.
