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.

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.

So far ahead of the curve in its day that it's still a monster synth, even in 2012. One of the most powerful features is that e.g. distortion is part of the voice, so you can play distorted chords on it without everything turning to unbearable mush. Being able to use algebraic functions for modulation is amazing, and hard to find on any other synth. To my ears, the ROM samples aren't so great as many make them out to be, but there's nothing really wrong with them either. But it's a sampler too, so that's not a deal breaker. A great synth then, a great synth now.

I've had a Kurzweil k2000r for a couple of years now, triggered by an Ensoniq SQ80 (and before you start, I know that's a travesty). But the ensoniq is dying and I saw a K2vx for $700aud. I picked it up (and god is it heavy), but already I can hear the difference! I've yet to get my head around the sequencer, and I'll miss the simplicity of the ensoniq, but once it's sorted, I just know my songs will sound awesome. I'm actually really excited about my new purchase, except of course for the manuals, which for an idiot like me of course make no sense! ;-)

Little problem that I have with my k2000. I have a k2000 v3 and the problem is loading samples from disk. I installed 32 mb of ram (2x16) but when I attempt to load samples from zip I get the message "no sample memory installed". What am I doing wrong? I noticed there are 4 slots for ram but since I installed only 32 I am using only 2. Should all for be occupied at once in order for this to work? Is there another way to diagnose this?? Any help would be appreciated

If you own a K2000S/2000RS, you can forget the analog out and use digital out directly (if you need stereo out).
go to : master, then sample, switch the input to "analog", 44.1khz. Then use a digital cable to your audio card ( a mic cable+ adaptor works in my case but not all will work depending on how they are wired).

Enjoy pure digital nirvana from the k2000 :-)
