Kurzweil K2500R rack module – with piano, orchestral & contemporary ROM boards, V3 with KB3 organs

 

Kurzweil K2500R MIDI rack module

Building on the acclaimed V.A.S.T. technology and the features that have made the award-winning Kurzweil K2000 Series the professionals’ choice worldwide, the Kurzweil K2500 Series goes several steps further. The 88 note K2500X feature a superb keyboard feel, an extensive user interface and the extraordinary processing power of Kurzweil’s most powerful instrument ever.

The K2500 and K2500X are more than “workstations”: they’re “Production Stations”. They enable you to complete a project – from conception to final master – without leaving the K2500 environment. Interfacing the K2500 with other digital and analog equipment is a breeze. And, of course, they have 8 MB of Kurzweil’s finest sounds on board, which can be expanded to 28 MB.

The K2500 keyboards have what you need for your most challenging projects: true 48-note polyphony; software upgrades from floppy or SCSI; 60 DSP functions; up to 28 MB of internal ROM sounds, 128 MB of sample RAM and 1.25 MB of battery-backed sequence/program memory; an array of controllers, including assignable pressure strips; dual SCSI ports; analog and digital I/O (with options).

Kurzweil instruments have always been known for their superb sound quality and powerful, state of the art sampling technology. With the K2500 and K2500X models, Kurzweil has added top-quality keyboards controller capabilities. The K2500X features 88 fully weighted piano-style keys.

The Kurzweil K2500 & K2500X are also full-fledged MIDI controllers with a wealth of assignable control sources. An expressive pressure strip, centered above the keyboard, can be programmed in three zones or one long zone to provide a “touch and hold” facility. A short pressure strip and two buttons near the pitch and mod wheels add dramatically to the instruments’ expressiveness. The front panel also incorporates eight independently assignable sliders, eleven assignable buttons with tri-colored LEDs, and three sequencer buttons.

The rear panels of the K2500 and K2500X provide additional controller inputs and interfacing options. The controller inputs include four footswitch, one breath-controller and two continuous control pedal jacks. Connectivity is easy with two 25-pin SCSI connectors and MIDI In, Out and Thru (MIDI Thru switchable to a copy of MIDI Out). Rear panel outputs include a pair of mixed audio outs, eight individual audio outs (which double as inserts) and one headphone output. Add K2500 Options (SMP-2X Sampling Option, KDFX Digital Effects Option or DMTi Digital Multi Track Interface) for a full range of additional digital I/Os and data conversion facilities.

The Kurzweil K2500 Series is a major step forward in electronic musical instrument technology. Each instrument combines a powerful sampler, effects processor, software-based sequencer, hierarchical file directory system, true 48-note polyphony, flexible interfacing and Kurzweil’s uniquely powerful V.A.S.T. processing technology, all in one unit.
