Use Case

Useful if you own a Roland W-30 sampler and want to:

  • Load modern WAV samples into the W-30
  • Create custom sample libraries for the W-30
  • Organize and manage samples on W-30 disk images
  • Fix issues on existing W-30 disks

The app makes it easier to use the W-30 with modern audio workflows by converting standard audio files into the W-30's proprietary format.
