Overview
What is a GKH file? A GKH file is a disk image used by various Ensoniq EPS family synthesizers and related Ensoniq instruments. It represents a complete copy of a floppy disk used by these hardware devices, storing musical data, such as sampled sounds, instruments (voices), sequences, and song information exactly as they were saved on the original disk.
More Information The format is associated with several Ensoniq models, including the EPS, EPS-16+, VFX, SD-1, TS-10/TS-12, and ASR series. These instruments relied on floppy disks to load and save sound libraries and user-created content. The GKH format preserves the original floppy disk structure, making it useful for archiving, sharing, and restoring Ensoniq disks without relying on aging physical media. NOTE: Musicians, sound designers, and collectors who work with vintage Ensoniq hardware or maintain legacy sound libraries are most likely to encounter GKH files.
