Roland XV-88 KEY Scale, 174, Equal Temperament, Just Temperament Tonic of C, Arabian Scale

Chapter 9. Getting More Familiar with the XV-88 (System Functions)

KEY SCALE

If you wish to define a scale for use in Performance mode/ GM mode, press [SYSTEM] while in Performance mode, and then press [TUNE] located in the row of function buttons to access the KEY SCALE page.

In Performance mode/GM mode, make the scale settings for each key in each Part. To make settings for another Part, use the cursor buttons to select the desired Part.

Equal Temperament

This scale divides an octave into 12 equal parts using the tuning system that is most widely used in Western music. The XV-88 employs equal temperament when the Scale Tune Switch is set to OFF.

Just Temperament (Tonic of C)

With this tuning, the three fundamental chords sound richer compared to equal temperament. This effect only applies to one key, and transposition can produce less- pleasing results.

Arabian Scale

In this scale, E and B are a quarter note lower and C#, F# and G# are a quarter-note higher compared to equal temperament. The intervals between G and B, C and E, F and G#, Bb and C#, and Eb and F# have a natural third— the interval between a major third and a minor third. On the XV-88, you can use Arabian temperament in the three keys of G, C and F.
