⚠️ Free real-time tuners generally don’t support graphic/melody-style editing – only automatic correction.

Users can force the vocal to stay within specific musical scales (Major, Minor, Chromatic, etc.) or create custom note maps. This ensures the vocalist never hits a "wrong" note relative to the song's key.

The secret lies in two knobs: Speed and Tolerance.
