This is the largest library, the largest collection of sounds for the Kurzweil K2x00-compatible family of VAST synthesizers anywhere.

You are bidding / purchasing a large library of Kurzweil Systems VAST compatible synthesizers. Those compatible synths are: K2000, K2000VP, K2000R, K2000RS, K2500, K2500X, K2500XS, K2500R, K2500RS, K2600, K2600X, K2600R, K2600RS, K2661, PC3K6, PC3K7, PC3K8.

We’ve spent years collecting these sounds from around the Internet and have been checked for accuracy and organized into individual memory loads for your synthesizer. In addition to the Disk Files and SysEx Patch / Program dumps, manuals in PDF format are also included.

We deliver these sounds to you as quickly as possible after payment. 

Why buy a SoundEngine Rebuild Kit?

  • We’ve authored detailed, specific installation instructions that show you what settings to adjust on your synthesizer, and what tools to use on your computer to use these sounds 

  • We focus on one synthesizer per library. We don’t group several synths together in a jumbled mess with lots of useless stuff in one package to get the sound count up 

  • We’ve tested and organized these sounds, and in many cases tagged them with keywords (BS, DR, SY, etc.) to make them fast and easy to use 

  • We will keep you updated as we find and develop new sounds that are included in our Rebuilds, so you always have the latest stuff both sound and documentation 

  • We will always, ALWAYS, give you free support and resend the sounds if you have a computer disaster - just ask our customers! 

  • Check the competition - they claim more data and sounds, but they include photos, videos, and other junk to fluff up the amount - we have more sounds!

SoundEngine has been programming synthesizers since 1991 and avidly collecting sounds for this and other synthesizers since the web really started taking off around 1995. We've been around and will be around to support you as needed.

What's included in this particular auction:

- More than 2.6+ GB of  Disk Files (.KRZ, .K25, .K25). 
- There are more than 700 .K25 files - these can also be loaded in the latest versions of K2000 firmware
        - There are more than 2800 .KRZ files 
        - In many cases (probably most cases) the .KRZ/.K25 files contain BANKS of sounds - not just singles.

- Documentation, including Programming Notes, Manuals, Base Objects and ROM expansion information
- MOST IMPORTANTLY: Lifetime updates and backups as needed. 
- If your Library is damaged or lost - we will replace the library for FREE!

This isn't a jumbled up mess of different Kurzweil synthesizer .KRZ files claiming to be the largest collection. This is a curated collection of .KRZ, .K25, and .K26 ONLY sounds and samples - thousands upon thousands of them - focused on these two synths. No other junk is included.

Rescue your synth with our rebuild kit! Thank you for browsing our auction and we look forward to your business.
