SFList JSON Editor

A visual editor for the SFList JSON format — a SoundFont playlist format used with BASS MIDI.

Live at sflist.losno.co

Features

• Create, open, and save .sflist.json files
• Add SoundFont entries (.sf2, .sf3, .sfz) and nested .sflist.json includes
• Edit gain, MIDI channel assignments (1-48), and patch mappings per entry
• Load SF2/SF3 files to populate a searchable preset picker grouped by bank, with drums sorted to the bottom
• Live JSON preview sidebar with copy-to-clipboard
• Reorderable entry list with animated transitions
• All state persisted to localStorage (with consent gate)

Important

The .sflist.json file must live in the same directory as your SoundFont files, since it references them by relative path.
