    EnDiskEx

    Bulk extractor for Ensoniq-formatted disk images

    EnDiskEx is a command-line tool that bulk extracts instruments, sequences, songs, and banks from Ensoniq-formatted disk images (RAW, GKH, EDE, and EDA) for the EPS/ASR family of samplers. The extracted files are saved as EFE / SMF / TXT files. EnDiskEx is designed to extract Ensoniq banks for re-creation within a different DAW. It will track down the instrument and song files from bank references even if they were saved on another disk. There also exists a disk mapping feature to correct for any errors in this process caused by having relabeled disks, forgotten to label disks, etc. EnDiskEx has been tested and validated against a variety of RAW, GKH, EDE, and EDA images files the dev team has, including but not limited to, the ASR factory disks, the EPS 16+ factory disks, and the EPS (classic) factory disks.
