Convert EXS to DLS

Understanding EXS and DLS file formats

EXS files are instrument definition files used by Logic Pro's EXS24 Sampler. They contain information about how audio samples are mapped across a keyboard, including velocity layers, key ranges, and other parameters. EXS files do not contain the actual audio data, but rather reference external sample files (usually in WAV or AIFF format).

DLS (Downloadable Sounds Level 1/2) files are standardized instrument banks defined by the MIDI Manufacturers Association. DLS files bundle instrument definitions and their associated audio samples, making them widely compatible with various MIDI synthesizers and software.

Why convert EXS to DLS?

Converting from EXS to DLS allows you to use your Logic Pro instrument banks in a broader range of MIDI-compatible software and hardware. DLS is a more universal format, especially for game audio and cross-platform music production.

How to convert EXS to DLS

There is no direct, one-click converter for EXS to DLS due to the complexity of instrument mapping and sample management. However, you can achieve this conversion through a two-step process:

1. Export your EXS instrument as SF2 (SoundFont 2) using a tool like Chicken Systems Translator or Extreme Sample Converter. These tools can read EXS files and export them as SF2, which is structurally similar to DLS.
2. Convert SF2 to DLS using Awave Studio by FMJ-Software. Awave Studio can import SF2 files and export them as DLS Level 1 or Level 2 files.

Recommended software for EXS to DLS conversion

• Chicken Systems Translator (Windows/Mac): Reads EXS and exports to SF2.
• Extreme Sample Converter (Windows): Converts EXS to SF2.
• Awave Studio (Windows): Converts SF2 to DLS. Use File → Save as... and select DLS as the target format.

Step-by-step conversion process

1. Open your EXS instrument in Chicken Systems Translator or Extreme Sample Converter.
2. Export the instrument as an SF2 file.
3. Launch Awave Studio and open the SF2 file.
4. Go to File → Save as... and choose DLS as the output format.
5. Save your new DLS file, ready for use in compatible MIDI software and hardware.

Important considerations

• Some advanced EXS features (like complex modulation or scripting) may not translate perfectly to DLS.
• Always check the mapping and sound quality in the resulting DLS file.
• Keep your original sample files organized, as both EXS and DLS reference external audio data.
