Instruments and their licences

midi-sink plays Decent Sampler presets and libraries: a .dspreset file with its samples beside it, or a .dslibrary that holds both. The format is Decent Sampler’s, and a format is not something a licence can fence off — file formats are not copyrightable, which is why any sampler may read one. What midi-sink reads of it is documented honestly: the compat report a library shows once, calmly, lists what it asked for that this version plays without.

The app bundles no libraries. One tiny demo instrument ships so that a first launch makes a sound: the Dan Tranh, a Vietnamese zither, sixteen notes from the Versilian Community Sample Library (VCSL), released to the public domain under CC0 1.0 — its licence text travels in the app beside the samples. Everything else you play is yours: libraries you bought, downloaded or made, each under its own terms. midi-sink copies a library you import into its own folder and never sends it anywhere; sharing a preset of yours shares the settings, never the samples.

Third parties inside the sound engine, all permissively licensed: miniaudio (public domain / MIT-0), pugixml (MIT), miniz (MIT), dr_wav and dr_flac (public domain / MIT-0), and the app’s own code under AGPL-3.0. The synth, Suzu, is the app’s own code and bundles nothing. The sound guide →
