What is a KRZ file? A KRZ file stores data saved from a Kurzweil K2000 series synthesizer, a workstation keyboard used for music production and sound design. It may contain sample data, instrument programs, MIDI sequences, and song arrangement information. Musicians and producers use KRZ files to save performance and project data created with the synthesizer.

More Information Kurzweil introduced the K2000 in the early 1990s as a digital synthesizer capable of sample-based synthesis using its Variable Architecture Synthesis Technology (V.A.S.T.) engine. Users often saved their custom sounds and compositions to floppy disks in KRZ format for later use or for transfer between devices. While primarily associated with the K2000, some later models like the K2500 and K2600 also supported this format.
