Kurzweil K2000

The K2000 uses V.A.S.T. (Variable Architecture Synthesis Technology) which allows you to take any multi-sample, noise or waveform and process it using just about any synthesis technique. The source of these multi-samples are from the 8MB of ROM which hold tons of authentic and superb quality samples. The internal processing is 32-bit with 18-bit DACs. The K2000 uses 31 sound-shaping algorithms to provide a variety of resonant filters, EQs, continuous panning, amplitude modulation, crossfade, distortion, digital wrap, waveshaper, pulse width modulation, high frequency enhancement, low frequency oscillators, hard sync oscillators and mixing oscillators, all with real-time MIDI control.

It's a beautiful synth with an elegant and organized layout and very high quality pitch and mod wheels! Not to mention a 61-note velocity & aftertouch sensitive keyboard with a quality feel and response to playing. The K2000s adds a quality sampler with standard 2MB RAM that can be expanded to 64MB. Sample in stereo or mono, via analog or digital inputs and you have all the sample edit functions you'll need to create some of your own sounds. Use the built-in 3.5" disk drive or connect an external drive to the SCSI port for limitless sample storage (an internal SCSI connection also allows for a hard disk drive inside).


Other professional features include stereo multi-effects capable of four simultaneous effects including reverb, chorus, delay, multi-tap delay, flange, rotary simulation and more. Up to six polyphonic audio outputs. There's also the 32-Track sequencer, fully editable, with features like 768 ppq resolution and nondestructive track editing and groove quantizing.

The K2000rs (pictured below) is the rack-mount version of the K2000s. Offering all of the same great sounds, power and features as the keyboard version. The K2000's keyboard is excellent and feels great to play, but if you don't need the extra keys the 3-space rack-module is an excellent instrument. The K2000's have been used by Robert Miles, Pink Floyd, Jean Michel Jarre, Depeche Mode, Hardfloor, Tori Amos, Stevie Wonder, Nick Rhodes (Duran Duran), Bon Harris (Nitzer Ebb), Front Line Assembly, KMFDM, LTJ Bukem, Nine Inch Nails, Massive Attack, Vangelis, Tangerine Dream, Laurent Garnier, and Luther Vandross.

Upgrades include the Orchestral Expansion Board (8 Mb) and Contemporary Expansion Board (8 Mb). A full 16-bit sampler with analog/digital sampling options (SMP-K) and AES/EBU and S/PDIF digital I/O ports. The 2MB sampler RAM is expandable to 64 MB for upwards of 19 minutes of sampling time. Sequencer's capacity is expandable from 30,000 events to 190,000. The operating systems can easily be upgraded too.

The K2000 was incredibly far ahead of it's time indeed. Even for 2012. I think the main thing is that people got stuck on the 80s era canned sounds and didn't take the time to understand how to use it as a synthesizer. It's one of the most incredible and deep synthesizers ever designed. My only complaint is that there's a somewhat characteristic sound to it that favors some material over others - it's INCREDIBLE at string sounds and PWM etc. But yeah - I really haven't heard anyone do something that comes close to challenging it's capabilities. The K2000 will be back. I promise.

Not sure about KRZ to sysx. but midi quest is supposed to be able to read write and edit to about 600 bits of hardware via midi K2000 included!

Is there an easy a way to convert K2000 patchbanks in krz. format
to midi sysyex?

VST is GREAT until you crash during a gig. You can load so many formats for sounds, I find I can convert and load almost anything I use in the studio. I seldom need to use the internal rom sounds. VAST is AWESOME! These things are built like a tank and I have very little trouble with mine. I would suggest updating to the latest OS for best results. I'm keeping mine!

Reality check time! A synth regarded as the creme de la creme in its day, but note the following: library load times/editing are a killer. VAST synth architecture will take a VAST amount of time to master. This thing uses SCSI, not USB - maintenance headaches, slow sysex editing. Get a modern synth where you spend more time making music than being your own IT department. I was looking at a used K2000R. Wonderful, solidly built piece of kit, but why buy when I can have massive libraries ready to go in modern day romplers and VSTs without the waiting to die load times that sound just as good.
