Upper Octave; Master Tuning; Scale Tuning - Yamaha PortaTone PSR-550 Owner's Manual

Upper Octave

This determines the Octave setting for the right-hand range of the keyboard, letting you
have independent ranges for the right and left hands. The range is from -1 to 1.
• Use the data dial, the [+/YES] button or the [-/NO] button to set the Octave.

Master Tuning

The Master Tuning function sets the overall pitch of the PSR-550.
The range is from 414.6 Hz to 466.8 Hz.
• Set the value with the data dial, the [+/YES] button or the [-/NO] button.

Scale Tuning

Scale tuning allows each individual note of the octave to be tuned over range from -64
to +63 cents in 1-cent increments (1 cent = 1/100th of a semitone). This makes it
possible to produce subtle tuning variations, or tune the instrument to totally different
scales (e.g. classic or Arabic scales).
The PSR-550 also provides nine different scale settings (shown below) that let you
instantly reconfigure the tuning of the instrument for playing in special scales. You can
tune the instrument in two ways: select the desired scale setting template, or tune each
key individually using Note Edit.
