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.

If some of you have any questions feel free to email! I have been working indepth with this synth for some time. Learning her inside and out! If you learn to program VAST, and use the Sweetwater site for patches your golden...the built in sounds are absolute crap, don't judge a book buy it's pre-programed cover. I live with 2 dj's that would now agree, and what i have made come out of this synth is amazing with the proper connections.

many years ago I hoped to purchased some great new modern Do-it-all, synthesizer but could only afford a used Kurzweil K2500 with plans to someday upgrade to a new Motif, korg or Roland workstation since brand new Kurzweils cost way too much. about 10 years later, after learning how to program and get the most out of my K2500, the desire to get a brand new workstation has completely vanished. I'm getting a K2000 v3. to see how I can use these together. Any suggestions out there? You must learn how to program and perform with it. A laptop with VST instruments + Kurzweil is all you need

This synth uses different converters to the k2500/600 etc - *that's* mainly why it sounds warmer than the later ones, not as a lot of people think just because of having different effects. It actually sounds better, and less anonymous.

I bought mine new, K2vx ver,cost over 4k. It has always had various problems but I liked the sounds and the logical layout.
I've since picked up several used and have backups when things go bump. Pram board does have glitches,the backlight poor ,power supply prone to problems and case has weak screw mounts,buttons and encoder wheel get worn out. K2000 could only SPLIT keyboard in to 3 zones instead of 8 and Kurzweils are a bit heavier.Yet it remains my primary instrument and I don't see a reason to change.

I would like to share a solution to a problem that has occurred twice on my K2000 by first version from 1991. The symptom was that the disk drive just shone, the screen shone empty and the OS not booted. The solution was to unscrew the P-RAM, underneath sits PROMs for the operating system. Push (or remove and put them back again) these PROM modules properly, then test the synth without screwing back the P-RAM to see that every step working. Screw back the P-RAM. Sorry for the bad english and technical terms, using Google translate from English. Wanted to quickly share this valuable knowledge.
