note-noodle provides interactive music theory practice for fretboard work, staff notation, ear training, rhythm, and play-along, alongside a guided curriculum. Play Along grades pitch and timing while a user plays through a microphone, MIDI keyboard, or screen. It accepts MIDI and Guitar Pro files up to 5 MB; free accounts can upload three per month. The curriculum has 35 lessons, quizzes, unit exams, spaced repetition, and seven learning paths. Ear training spans eight categories and four difficulty tiers, with answers by ear, MIDI, or microphone. Four digital instruments send per-note bend, slide, and pressure across up to 15 member channels; hearing per-note bend requires an MPE host such as Live 11. A MIDI Bridge connects those instruments to a desktop DAW over the local network. Free access includes 10 ear-training sessions per day and the first four lessons without an account. Premium costs €7 a month. The service runs on Android, Linux, macOS, web, and Windows.
