Part Octave; Master Tuning; Scale Tuning; Split Point - Yamaha PortaTone PSR-540 Owner's Manual

Part Octave

This determines the relative octave settings for the keyboard-played voices R1, R2 and
L.
• Select the part (R1, R2, L) by pressing one of the PART ON/OFF buttons
(VOICE R1, VOICE R2, VOICE L).
• Set the value with the data dial, the [+/YES] button or the [-/NO] button.

Master Tuning

The Master Tuning function sets the overall pitch of the PSR-540.
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 Accompaniment and Multi Pad sounds are affected by Scale Tuning.
• Select the note to be tuned by pressing the [NEXT]/[BACK] button.
• Tune the selected note by using the data dial, the [+/YES] button, the
[-/NO] button or the number buttons [1]-[0].

Split Point

The point on the keyboard that separates the auto accompaniment section and the right-
hand section of the keyboard is called the "split point."
• When the auto accompaniment is on, keys played to the left of the split point are
used for controlling the auto accompaniment (page 33).
• When the auto accompaniment is off, keys played to the left of the split point are
used for playing voice L (page 28).
• Set the value with the data dial, the [+/YES] button or the [-/NO] button.
