In addition, a General MIDI 1 sound set is provided for convenient authoring of MIDI files for the World Wide Web. There will be new sounds for the Kurzweil K2661. These sounds will be compatible with the K2600s that include ROM1 and ROM2.

Kurzweil is known worldwide for our quality instruments that are being constantly upgraded, not outdated. All Kurzweil K2000, K2500, and K2600 Series libraries are forward compatible with the Kurzweil 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.

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. Kurzweil's 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 Kurzweil K2661 is the clear choice for any sound professional.

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 Kurzweil K2661 I/O can be routed through KDFX including 8 outputs and 8 inputs from the ADAT digital I/O or analog sampling I/O.

KB-3 Organ Mode
The KB-3 Organ Mode found in the Kurzweil K2661 accurately models a Tone Wheel Organ. The sliders and mod wheel on the Kurzweil K2661 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.

Professioal 32-Track Sequencer
The Kurzweil K2661's full-function 32-track sequencer is equipped with many features found only 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 work on a computer sequencer, or wants to use a computer for additional development, the Kurzweil K2661 can import and export either Type 1 or Type 0 MIDI files on DOS format media. The Kurzweil K2661 sequencer is the most sophisticated sequencer of its kind available.

Kurzweil Ultra-Realistic Sounds
The Kurzweil 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 Kurzweil 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. The Kurzweil K2661 offers over 575 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 Kurzweil K2661 uses a file format that is Kurzweil 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 Kurzweil 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 Kurzweil K2661 gives the Kurzweil owner access to the largest sound library in the world.

Complete MIDI Control
The Kurzweil K2661 is a complete MIDI controller. The front panel of the K2661 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 k2661 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 K2661 breath controller input accepts Yamaha BC-1, BC-2, and BC-3 breath controllers.

If you are composer, film scorer, stage musician or you just love playing keyboards, then the Kurzweil K2661 is the one for you. It's almost everything that the K2600 series has to offer and more but without the bulkiness of a larger Kurzweil. Maybe I should preface my next statement by saying that I'm not a good keyboard player, in fact, I'm a one-finger-on-a-pad wonder. There are a ton of keyboards out there, all of which are pretty complicated and sometimes overwhelming when you look at all the buttons. However, from the moment I fired up the keyboard, I noticed that this wasn't the case. Everything is very straight forward and even if you're not a keyboard player, this isn't an overwhelming one to get into. Just turn it on, and start jamming. Another thing I wanted to note was, after I started playing with it, I couldn't get off of it. It was too addicting and before I knew it, It was 4 AM and I was making, what I thought was music, with just one finger! Every sound that is packed with this keyboard has unique characteristics to it. Nothing sounds like an overused sound sample that has been re-EQ'ed just to change the sound. The best way I could describe the sounds would be rich, lush, and very deep with multiple hues within each sound. The KDFX processor that comes pre-installed in this keyboard sounds so good that Kurzweil had to bottle it up separately and use it as a stand alone device. The algorithms are natural sounding and every aspect of it sounds real. I strongly reccomend this product to anyone who is a novice, an expert or anything in between in the music industry.
