Licenses & Third-Party Notices
Last updated: July 18, 2026
NotationAI uses official store badges, openly licensed playback engines, and openly licensed sample libraries. This page identifies those sources, their licenses, and required attribution notices.
Instrument-counting transparency
NotationAI exposes 200+ selectable instrument profiles. These profiles include the 128 General MIDI programs plus notation-ready variants such as transposing, sectional, and range-specific instruments. They are selectable score identities, not 200+ unrelated recording sessions.
Every profile plays on both clients from licensed compressed samples. Web additionally selects 100+ verified HQ presets; the App currently shares the canonical FluidR3 source family rather than claiming identical renderer DSP or HQ preset coverage.
