How to edit SoundFont presets: volume, pan, tuning and filter

Beyond merging and splitting, Rsf2 lets you edit each SoundFont preset and hear the result before exporting — no desktop sampler required.

What you can adjust

Volume, pan, tuning, attack, release and a low-pass filter (brightness cut) on each preset.

Step by step

1. 1Load the .sf2 and tap the preset you want to edit.
2. 2Adjust the controls (volume, pan, tuning, attack, release, filter).
3. 3Play notes on the on-screen keyboard or a MIDI controller to listen.
4. 4When happy, export the new .sf2 with your edits.

Note

Leaving a control at neutral (0) keeps the preset byte-exact. The filter can only darken the sound (low-pass): it cannot add brightness the sample does not have.
