The Kurzweil K2700 represents the pinnacle evolution of the legendary K2 Series Workstations, delivering unprecedented power and versatility for the modern musician, producer, and performer. This flagship instrument combines decades of Kurzweil innovation with cutting-edge technology to create the ultimate musical workstation experience.
Revolutionary Sound Engine
At the heart of the K2700 lies an incredibly powerful sound engine featuring 256 voices of V.A.S.T. polyphony—over 5 times the polyphony of any previous K2 series model. This massive polyphonic capacity ensures that even the most complex performances and productions never run out of voices, supporting the most demanding sonic explorations without compromise.
Extensive Sound Library
The K2700 delivers an extraordinary 4.5 gigabytes of factory sounds, serving up a deep sound library of over 1500 factory Programs and more than 700 Multi combinations. These sounds are meticulously organized into 13 instrument categories ranging from Pianos to Synths to Orchestral sounds and beyond. The library features optimized German D, Japanese C7, and Triple Strike pianos, Classic Tine EPs ('73 & '77), plus updated sounds from Kurzweil's popular SP6, PC3/4, and KORE64 expansion collections.
FlashPlay® Technology and User Memory
Kurzweil's patented FlashPlay® technology provides the K2700 with staggering computational horsepower, offering up to 8 GB total capacity with zero loading time and ultrafast performance. Users can load up to 3.5 GB of their own custom samples into non-volatile flash memory, with support for multiple sample formats including .WAV, .AIF (up to 16-bit/96kHz), and various Kurzweil formats (.FOR, .PC4, .P3K, .KRZ, .K25, .K26).
Advanced V.A.S.T. Architecture
Born in the original K2 series, V.A.S.T. (Variable Architecture Synthesis Technology) reaches new heights in the K2700. The system offers 32 layers per program with deeply customizable signal paths and a comprehensive host of modular DSP tools including new oscillators, filters, and effects. The innovative Cascade Mode allows users to route one layer through the DSP of any other layer within a program—up to 32 consecutive layers deep—for unprecedented sound design possibilities.
Multiple Synthesis Engines
The K2700 incorporates several powerful synthesis engines:
6-Operator FM Engine: A sophisticated FM synthesis system capable of loading original FM SysEx files. FM layers represent a revolutionary addition to VAST programs and can be seamlessly combined with traditional VAST features to transcend the boundaries of classic FM synthesis.
Virtual Analog Technology: Embedded within the K2700 are powerful anti-aliasing, power-shaped oscillators along with DSP processing from Kurzweil's mythical VA1 concept synthesizer, delivering authentic analog emulations alongside incredibly complex new sounds.
KB3 ToneReal™ Organs: Modeled after classic tonewheel organs, featuring a full complement of immediately accessible tonewheel controls including 9 realistic drawbars, rotary speed control, chorus/vibrato, brake, percussion, and more.
Professional Effects and Processing
The K2700 features an award-winning effects engine with over 1000 complex effect chains incorporated into programs. This comprehensive suite includes reverbs, delays, choruses, flangers, phasers, distortions, rotary amplifiers, compressors, and more—all fully editable from the user interface. A global Master FX section provides 3-band EQ and compression for final mix polishing. Additionally, Kurzweil String Resonance (K.S.R.) modeling enhances acoustic piano performance with authentic string resonance behavior.
Premium Performance Interface
The K2700's 88-note fully-weighted Italian hammer-action keyboard with aftertouch provides an exceptional playing experience. Every sound is perfectly matched to the keyboard's response characteristics, with customizable MIDI velocity and pressure settings to suit individual playing styles. The instrument's 16-Zone Multi Controller Mode enables massive sonic combinations through Kurzweil's renowned Multi mode, offering 16 zones of unparalleled MIDI controller capabilities with each zone supporting over 60 separate physical controllers.
Comprehensive Sequencing Capabilities
The K2700 features extensive sequencing capabilities designed for complete in-the-box music production:
16-Track Sequencer: A full-featured internal sequencer for recording, editing, mixing, and producing complete tracks. The system supports MIDI file import (.mid) as well as Kurzweil PC3/PC4/Forte-family songs.
16 MIDI CC Sequencers: Add sonic animation through 16 simultaneous MIDI CC Step Sequencers for comprehensive modulation sequencing.
16 Riff Generators: Trigger and manipulate up to 16 simultaneous MIDI sequences on the fly, with options to select from an internal library of patterns or record/import custom sequences.
16 Note Arpeggiators: Activate up to 16 independent arpeggiators (1 per program, 16 per Multi) with access to an advanced Step Sequencer environment for rhythmic pulse creation and manipulation.
Intuitive Control Interface
The K2700 provides extensive hands-on control through multiple interface elements:
Built-In Ribbon Controller: Configure for single-section operation across its entire length or three independent sections of equal length. Control pitch bending, filters, volume, tempo, distortion, and virtually any parameter.
16 Pad Triggers: A 4×4 grid of velocity-sensitive pads for precise drum and percussion triggering, zone mutes, note/chord triggers, filter control, layer addition, arpeggiator control, and CC sequencer manipulation.
Programmable Controls: 9 sliders, 9 knobs, and 10 buttons, all fully programmable for internal parameter control (volumes, pans, filters, FX wet/dry, envelopes, mutes) or external MIDI CC transmission to DAW hosts.
Navigation and Display: A clear, easy-to-read 4.3″ widescreen color LCD display (480×272) with categorized sound selection featuring customizable category defaults. Master transport controls provide command over the onboard 16-track sequencer and external DAWs via MMC and System Real-Time messages.
Professional Audio Interface and I/O
The K2700 features an integrated USB audio interface, eliminating the need for separate hardware when recording to a DAW. Users can connect line, instrument, or microphone sources and route audio from the K2700 and its analog inputs to their DAW, with or without effects processing. The audio interface section includes per-channel gain knobs, peak-level LEDs, Hi-Z switching, and +48V phantom power.
Live audio inputs via 1/4″-XLR combo inputs allow jamming with external audio sources, with dedicated real-time effects processing for texture creation. Professional balanced audio outputs provide connection to mixers, amplifiers, or studio monitors through four 1/4″ TRS balanced outputs arranged as two stereo pairs (A & B). Premium 32-bit D-to-A converters ensure pristine audio quality, with automatic mono switching on main outputs and a back-panel 1/4″ stereo headphone jack.
Comprehensive Connectivity
USB connectivity provides MIDI, audio, and storage functionality through a single cable, allowing the K2700 to function as both MIDI controller and audio source with DAW software. USB Host functionality enables connection of USB class-compliant devices such as alternate keyboard controllers or external fader/knob units. The system also supports storage of custom content and system updates via USB.
