Boston DSP-488 - Appendix; Auto Accompaniment Fingering

33
SINGLE Mode fingering makes it simple to produce beautifully orchestrated
accompaniment using major , seventh , minor and minor-seventh chords by
pressing a minimum number of keys in the Auto Accompaniment section of the
keyboard . The accompaniment produced is perfectly matched to the currently
selected accompaniment style.
If you press a “C”key in the left-hand section of the
keyboard, for example, a C-major accompaniment will
be played. Press another key in the left hand section of
the keyboard to select a new chord. The key you press
will always determine the "root" of the chord played
(i.e. “C” for a C chord).
