Convert PCG to SF2

Understanding PCG and SF2 file formats

PCG files are program/combi bank files used by Korg synthesizers, such as the Korg Triton, Kronos, and M3. These files store sound programs, combinations, and global settings, but do not contain actual audio samples. Instead, they reference internal or external sample data.

SF2 (SoundFont 2) files are a widely used format for storing sampled instrument sounds. SF2 files contain both the audio samples and the mapping information needed for playback in software and hardware samplers.

Why convert PCG to SF2?

Converting PCG to SF2 allows musicians to use Korg synth sounds in software samplers, digital audio workstations (DAWs), or other hardware that supports the SoundFont format. This is especially useful for integrating classic Korg sounds into modern music production workflows.

Conversion process overview

Direct conversion from PCG to SF2 is not straightforward, as PCG files do not contain audio samples. The process typically involves:

• Extracting or sampling the actual sounds from the Korg synthesizer.
• Mapping these samples to a new instrument using a SoundFont editor.

Recommended software for conversion

There is no one-click converter for PCG to SF2, but the following workflow is effective:

1. Use Korg PCG Tools to view and manage PCG files. This helps identify the programs and combinations you want to convert.
2. Sample the desired sounds from your Korg synth using audio recording software (e.g., Audacity or your DAW).
3. Edit and trim the samples as needed.
4. Use a SoundFont editor such as Polyphone (free, Windows/Mac/Linux) to create a new SF2 file. Import your samples and map them to the appropriate keys and velocities.
5. Export the finished instrument as an SF2 file via File → Export → SoundFont in Polyphone.

Tips for best results

• Record samples at multiple velocities for more expressive instruments.
• Carefully loop and trim samples to avoid clicks and pops.
• Use consistent naming conventions for easy management.

Summary

While there is no direct PCG to SF2 converter, you can recreate Korg sounds as SoundFonts by sampling and mapping them with tools like Polyphone. This approach preserves the unique character of your Korg patches for use in any SF2-compatible sampler or DAW.
