If you are on stage or just want to quickly tune and play, Instant-Tuning Mode is just what you need. It only shows the most important elements for tuning.
The Note in the middle of the screen shows the detected note(Ab). The number on the right side (3) represents the octave.
In the Instant-Tuning Mode, the indicator becomes a color bar.
Bar on the left means the note is too flat, so you should sharpen it.
Bar on the right means the note is too sharp, so you should flatten it.
When the note is in tune, the background display will turn green.
