Professionals around the world use Kurzweil instruments for all their production needs. From Film Studios and composers to the U.S. Government, Kurzweil delivers the quality and award-winning audio that is required by the best.

Continuing this tradition, Kurzweil is proud to offer the K2661. Fully compatible with all Kurzweil K2x00 models, professionals can continue their work without interruption, always confident that archived work will be compatible.

Kurzweil's world-renowned V.A.S.T. architecture, enhanced with Triple Modular Processing, provides 127 algorithms to shape your sounds. In addition, the KDFX effects processors provide 5 stereo bus effects with 24 bit processing. The K2661 is a complete workstation, allowing the user to work from concept to completion without changing from station to station.

NON-OBSOLESCENCE

Kurzweil is known for quality instruments that are upgraded, not outdated. All K2000, K2500, and K2600 Series libraries are forward compatible with the K2661. This is how Kurzweil was able to build the largest sound library in the world. In addition, Kurzweil reads other major formats directly into the system for use with its V.A.S.T. architecture. New operating systems and options are always being created, expanding an artist's power while preserving his investment in time and programming.

V.A.S.T.

Kurzweil's award-winning Variable Architecture Synthesis Technology (V.A.S.T.) is the state-of-the-art synthesis system, giving an artist powerful expression not available with any other brand. V.A.S.T. can accurately model or emulate many synthesis processes offered by the competition, past or present. In addition, V.A.S.T. has many processes not available anywhere else. A simple comparison will prove the K2661 is the clear choice for any sound professional.

KB-3

The KB-3 Organ Mode accurately models a Tone Wheel Organ. The sliders and mod wheel are used as the drawbars for real-time control. This revolutionary synthesis modeling tool gives the user the power to blend harmonics in real-time to create and control unique new timbres. Full polyphony is always maintained, with a single-voice containing 9 harmonics that may be blended, controlled and/or recorded in real-time.

SEQUENCER

The K2661's full-function 32-track sequencer is equipped with many features only found on the most sophisticated software-based sequencers. With a maximum internal resolution of 768 ppq, sequencer functions include: Linear, Pattern and Step (Drum Machine), Record Modes, Reference Quantize, Event Edit List, Cut, Copy, Paste facilities, Advanced Auto Arranger functions (allows sequences to be triggered from keys with velocity sensitivity and transposition), grab (imports tracks from other sequences) and more. Reference Quantize allows the user to quantize to a groove track, and to quantize tracks not previously recorded with a click. The Event Edit List, with view filters and audible scroll, enables precise, computer-style editing. If the user already created some work on a computer sequencer, or wants to use a computer for additional development, the K2661 can import and export either Type 1 or Type 0 MIDI files on DOS format media. The K2661 sequencer is the most sophisticated available.

MIDI CONTROL The K2661 is a complete MIDI controller. The front panel also has eight independently assignable sliders, useful as MIDI sliders, for sequencer mixdown, or as organ drawbars in the KB-3 Mode. Two buttons above the pitch and mod wheels are completely programmable. The optional 600mm ribbon controller is programmable in three distinct zones or one long zone. Additional controllers include sequencer "transport control" buttons, 4 footswitch inputs, and 2 continuous control pedal inputs (1 CC and 1 CC/breath controller). The breath controller input accepts Yamaha BC-1, BC-2, and BC-3 breath controllers. The multitude of flexible controllers make the K2661 the ideal center piece for any MIDI production.

BALANCED OUTS

The K2600 includes 24-bit Balanced Audio Outputs with patented output circuitry that deliver professional audio signal levels (1/4" t/r/s). Unbalanced (1/4") outputs are also supported.

USER-INSTALLABLE OPTIONS

The K2661 user can install options including Sample RAM (up to 128MB) and Sound ROM boards.

LIGHTWEIGHT AND PORTABLE

The K2661 is the most portable keyboard in the K2600 family by far. Gigging musicians will appreciate the ability to take their most sophisticated production station out on the road.

LIVE MODE

Powerful V.A.S.T. DSP capabilities to process any incoming mono or stereo signal via the digital inputs or analog inputs (requires the sampling option). Imagine plugging your guitar, microphone, mixer or tape track directly into your K2661 and customizing the sound using any of the V.A.S.T. parameters, all in real-time. Then add effects using the K2661's state-of-the-art KDFX. The K2661 is the most advanced real-time signal processor ever created. With the ADAT/AES selectable optical I/O connections you get up to 8 inputs and 8 outputs which can bidirectionally communicate with other devices such as Adat Modular Digital Multitrack recorders or computer digital audio interfaces.

ON BOARD SOUNDS

The K2661 offers over 450 programs (with 100s more available) for a wide and useful selection. Handy search string functions allow the user to locate a program, setup or object quickly in memory. The K2661 uses a file format that is K2000, K2500, and K2600 compatible, enabling it to read Kurzweil or third-party sound libraries for each instrument from SmartMedia or any SCSI disk (such as CD-ROM). The K2661 can also read other manufacturers' sample libraries including Roland's(r) 700 Series, Akai(r) S1000, S1100 and S3000, and Ensoniq(r) EPS and ASR file formats. V.A.S.T. processing will give new life to these files. The K2661 gives the Kurzweil owner access to the largest sound library in the world.

INTERACTIVE SETUPS

The K2661 interactive setups allow for easy creative inspiration using multi-timbral "grooves." Kurzweil gives the user instant access to the most useful parameters for real-time control of programs and setups from a wide assortment of preassigned controllers.

CONNECTIVITY

The rear panels of the K2661 provides additional controller inputs for a multitude of interfacing possibilities. The controller inputs include the 600 mm ribbon controller, four footswitch, one breath-controller and two continuous control pedal jacks (1 CC pedal and 1 CC/breath input). Interconnection is easy with a 25-pin SCSI connector and MIDI In, Out and Thru (Thru switchable to a copy of Out). Rear panel outputs include a pair of mixed audio outs, four individual 24-bit balanced audio outs with Kurzweil's patented output circuitry, and one headphone output. In addition, optical ports provide selectable ADAT Lightpipe or S/P-DIF I/O. Add the K2661 Sampling Option (SMP-2X) for a full range of additional digital and analog inputs. The K2661 brings unparalleled control, distribution, and communication to your digital audio environment.

KDFX

KDFX (Kurzweil Digital Effects) utilizes Kurzweil's proprietary VLSI chips and DSP algorithms. It includes a versatile 5-stereo-bus design, 24-bit signal processing, cutting edge DSP functionality, and unparalleled real-time control, all with an extremely flexible routing scheme. All I/O can be routed through KDFX including 8 outputs and 8 inputs from the ADAT digital I/O or analog sampling I/O.

SOUND ROM

The K2661 has 32 MB of internal sound ROM, and two expansion slots for a total of up to 48MB of ROM sound samples. The internal sound ROM includes all of the samples from the K2600, the K2600's Orchestral and Contemporary ROM options, and a General MIDI 1 sound set. In addition, the Stereo Dynamic Piano, and Vintage Electric Pianos ROM options can be installed in the expansion slots.
