Instrument and Chromatic Tuners

• Most models of Korg tuners are chromatic tuners. These tuners simply read the pitch and display what note is closest to that pitch. The display then shows how flat or sharp the pitch is to that note. A few tuners are designed to just read the specific pitches for a particular tuning, for example E-A-D-G-B-e for guitar. These have a flat button that can allow for the meter to read a lower pitched note than E-A-D-G-B-e. If D-G-C-F-A-d tuning was needed, the tuner would be used as normal, except with the flat button pushed to display two flat symbols.
  
  

Meter Display

• The meter is the simplest and most common display used on Korg tuners. If the needle is pointing straight up, the note displayed is in tune. If the needle goes to the left, the note is flat. If the needle goes to the right, it is sharp. The goal is to get the needle straight up, and avoid even the slightest waver to the left or right. Simply pluck the open string and adjust the instrument tuning until the correct note is in tune.
  
  

Mirror Display

• The mirror display is fairly uncommon on Korg tuners as the only method of display. Some tuners do have it as an option, which may be more comfortable for some people to read. For this display, there are two lights on either side of the meter. The brighter light indicates if the note is sharp or flat depending on if it is the right or left light respectively. As the note goes to being in tune, the lights move towards the center until they converge.
  
  

Strobe

• There are two different variations to the strobe tuner. The first has several indicator lights moving across the display if the note is sharp or flat. The direction the lights move indicate this, with left to right indicating sharp and right to left indicating flat. The degree of sharp or flat is shown by how fast the lights move across the screen. When the note is in tune, two indicator lights come on and there is no movement on the screen.
  
  The second variation works in much the same fashion. The same conventions for reading the movement apply. The difference is that only one indicator light actually moves across the screen rather than several. In addition, the center light will come on to indicate the note is properly in tune.
