How does tonestro hear me play?

• Wind and string instruments: right notes turn green, missed ones red; a wrong note shows in red above or below. A line left of a note means too early, right of it too late.
• Expert mode (settings of a lesson or song): also shows small deviations in pitch and rhythm, in orange.
• Piano: a note turns green once it's right and red if you miss it. When tonestro waits for you, it turns orange after a few seconds and you see the keys.
• Once more: too many notes off in a course? You play the passage again.
• Where it listens: lessons, songs and the challenge, not theory lessons. Notes not recognized?
