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.

Love the K2000.

However I'm trying to burn CD's with .krz sounds that will be read by my K2000 (3.54).

As far as I know it's a Kurzweil kind-of-DOS format. Not ISO 9600. Since now I was using a Iomega SCSI zip.

Patches were loaded from my extensive .krz sounds collection (4 gigs +) to the zip drive from the PC via SCSI and then from the zip drive to the K2000.

Recently i got an iMac and a old Apple SCSI CD reader. The K2000 recognizes the CD reader but not the CD's with .krz patches since it was burned ISO 9660.

Any help would be greatly appreciated!

I wanted a powerful brand new supersynth but only could afford a used Kurzweil K2500s. I was extremely happy and with some software and the Yamaha TG500 module, my desire for a super synth vanished away completely. Becoming a Kurzweil lover/believer, I purchased a used K2000 v3. and when i thought of what else I could add to my set up after looking at a magazine of all the new great stuff, I could not find not one thing that interested me. By hooking up my K2500s with my K2000 and Yamaha TG500, I don't need ANYTHING else, by programming, the sound and power is extraordinary!

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.
