Convert SFZ to DLS

Understanding SFZ and DLS file formats

SFZ is an open standard file format for defining instrument sounds for software samplers. It uses a plain text format to map audio samples to MIDI notes and velocities, allowing for flexible and detailed instrument definitions. DLS (Downloadable Sounds Level 1/2) is a standardized format developed by the MIDI Manufacturers Association for packaging instrument samples and their mappings, commonly used in MIDI synthesizers and sound cards.

Why convert SFZ to DLS?

Converting SFZ to DLS is useful when you need to use custom sampled instruments in environments or devices that only support the DLS format, such as certain MIDI hardware, game engines, or legacy music software.

How to convert SFZ to DLS

There is no direct, one-click converter for SFZ to DLS due to differences in format structure and features. However, you can perform the conversion using a combination of software tools:

1. Extract samples and mapping from SFZ: Use a sampler like Sforzando or Polyphone to load your SFZ file and export the sample mappings.
2. Create a DLS instrument: Use Polyphone (a free soundfont editor) to import the samples and manually recreate the instrument mapping. Polyphone can export to DLS format via File → Export → DLS.

Note: Some advanced SFZ features may not be supported in DLS, so manual adjustments may be necessary.

Recommended software for SFZ to DLS conversion

• Polyphone (Windows, macOS, Linux): Free and user-friendly, supports both SFZ sample import and DLS export.
• Sforzando (Windows, macOS): Useful for auditioning SFZ files and extracting sample data.

Summary

While there is no automated SFZ to DLS converter, Polyphone offers a practical workflow for manual conversion. This process involves importing SFZ samples and mappings, then exporting the instrument as a DLS file, making your custom sounds compatible with DLS-based systems.
