Tuning Panel

The Tuning Panel contains controls for tuning a Key or changing its representation.  Controls in the Tuning Panel are applied to the last key played.  

In the center is a Tuning Slider. The unit of change for the slider is selected and displayed with the "pop-up" list below it.  The value of the key during tuning is shown in the panel's display, in the box above the slider.  The Representation used for this display is chosen with the "pop-up" list below it.  One can, for example, use the slider to tune a key in frequency, while viewing the result in cents.  Tuning may also be achieved by entering values in the display field by hand. 

You can change the representation of a Key or an entire window by choosing the desired representation style in the pop-up list below the display, and choosing Set for a single Key, or All for the window.

The Selection box contains buttons that effect the Selection of the current keyboard. Multiple keys may be selected at one time.  This is useful for listening to chords, or examining relationships within a subset of a tuning. With multiple keys selected, the Compare button will show their relationship in the chosen representation. Play will play the chord described by the selection.  Reference will make the last Key played the Reference Key for the window. The Reference Key is no different than other keys except that it acts as base in relative tuning representations. Any key can be made the Reference by using this button.
