KB-3
The KB-3 Organ Mode is standard on all K2600 series instruments. The sliders and mod wheel accurately model the drawbars of a Tone Wheel Organ. 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. KB-3 is just the beginning, future software enhancements will unlock the true potential of this new tool.

Sequence
The K2600'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 work on a computer sequencer, or wants to use a computer for additional development, the K2600 can import and export either Type 1 or Type 0 MIDI files on DOS format media. The K2600 sequencer is the most sophisticated available.

MIDI Control
The K2600 and K2600X are complete MIDI controllers. The 600mm ribbon controller is programmable in three distinct zones or one long zone. It can be assigned to respond to finger positions as follows: relative to absolute center; relative to "virtual center" (initial finger-press defines the virtual starting point); return to center when finger is removed; or maintain current value when finger is removed. A shorter, pressure and direction sensitive ribbon controller below the pitch and mod wheels allows natural vibrato and subtle nuances of expression. Two buttons above the pitch and mod wheels are completely programmable. 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. Additional controllers include sequencer "transport control" buttons, 4 footswitch inputs, and 2 continuous control pedal inputs (1 CC2 and 1 CC2/breath controller). The breath controller input accepts Yamaha BC-1, BC-2, and BC-3 breath controllers. The multitude of flexible control surfaces make the K2600 the ideal center piece for any MIDI production.

Balanced Outs
The K2600 includes 18-bit Balanced Audio Outputs that deliver professional audio signal levels (1/4" t/r/s). Unbalanced (1/4") outputs are also supported.

User-Installable Options
Now more accessible than ever, the K2600 user can install options including PRAM memory expansion (from 477K to 1.5MB), Sample RAM (up to 128MB) and up to four optional Sound ROM boards can be installed.

Improved Keyboard Action
Improved keyboard actions offer greater performance and reliability for the most demanding situations. Available in 76-note semi-weighted or 88-note fully-weighted keyboards.

Live Mode
Powerful V.A.S.T. DSP capabilities to process any incoming mono or stereo signal via the analog or digital sample inputs (pitch processing requires the sampling option). Imagine plugging your guitar, microphone (mic pre recommended), mixer or tape track directly into your K2600 and customizing the sound using any of the V.A.S.T. parameters, all in real-time. Then add effects using the K2600's on board effects or the state-of-the-art KDFX. The K2600 is the most advanced real-time signal processor ever created. With various digital I/O options such as the DADAT-26 ADAT I/O option card and the venerable DMTi Digital Multitrack interface (ADAT, TDIF, AES/EBU, SPDIF support) you get an 8 channel digital highway in and out of the K2600.

Upgrades
Kurzweil is renowned for its non-obsolescence through their design philosophy. With Flash ROM, the user can now easily upgrade their operating system from disk or SCSI and customize the factory program and setup lists, always keeping your instrument current with new features and technology. New software is made available via this web site or from your local Kurzweil dealer. The user may also choose to upgrade the K2600's program and sample memory: battery-backed program RAM can be expanded from 477K to 1.5MB via a cost-effective memory upgrade. Sample memory can be upgraded to 128MB for recording or capturing over 24 minutes of CD-quality sampled sound. The K2600 is the most flexible and upgradable instrument available.

On Board Sounds
The K2600 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 K2600 uses a file format that is K200 and K2500 compatible, enabling it to read Kurzweil or third-party sound libraries for each instrument from disk or CD-ROM. The K2600 can also read other manufactures' sample libraries including Roland's® 700 Series, Akai® S900, S950, S1000, S1100 and S3000, and Ensoniq® EPS and ASR file formats. V.A.S.T. processing will give new life to these files. The K2600 gives the Kurzweil owner access to the largest sound library in the world.

Interactive Setups
The K2600 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 K2600 and K2600X have been designed for better I/O placement. It also provides additional controller inputs for a multitude of interfacing possibilities. The controller inputs include four footswitch, one breath-controller and two continuous control pedal jacks. Interconnection is easy with two 25-pin SCSI connectors and MIDI In, Out and Thru (Thru switchable to a copy of Out). Rear panel outputs are balanced and include a pair of mixed audio outs, eight individual audio outs and one headphone output. Add K2600 Options (SMP-2X Sampling Option, DADAT-26 ADAT I/O or DMTi Digital Multitrack interface) for a full range of additional analog and digital I/O. The K2600 brings unparalleled control, distribution, and communication to your digital audio environment.

KDFX
Kurzweil KDFX is standard on all K2600s. KDFX utilizes Kurzweil's VLSI DSP chip. 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 Kurzweil Digital Stream (KDS + DMTi) digital I/O, or sampling I/O or DADAT-26 ADAT I/O. KDFX opens a whole new realm of possibilities for the K2600.
