Playing Styles Using the Entire
Keyboard
In “Play Along with a Style” on page 25 we described
a method of playing styles in which chords were
detected only to the left of the keyboard split point. By
making the settings described below, however, chord
detection for style accompaniment occurs over the
entire range of the keyboard, allowing for even more
dynamic style performance. In this mode Easy Chords
cannot be detected.
