Auto-Accompaniment System - Kawai Concert Performer CP136 Owner's Manual

Auto-accompaniment System

The Concert Performer Auto-Accompaniment System (ACC) analyzes your playing and adjusts
the note data recorded in the different Phrases in a pattern to match the root key and chord type
you are playing. The ACC System also shifts the octave for each phrase to keep each section playing
within its musically useful range. To get the most out of this System, any new Style you create can
benefit from some fine tuning of these settings.
When you press the DETAIL SETTINGS button (L5) on the Style Maker Record screen, the Style
Maker Detail Settings screen will be displayed.
Accompaniment Type (ACC Type)
This setting determines how Phrases being played by a particular section in a pattern will be
analyzed by the Auto-accompaniment (ACC) System. There are Two Accompaniment Types:
Chordal and Scalic (melodic). Chordal Phrases usually consist of block chords or arppegiated
chords. You should set this kind Phrase to Chordal. Scalic Phrases usually play melodic phrases
that serve to add interest to the style as well as provide counter melodies and riffs. Melodic Phrases
or Phrases that contain chromatic passages should be set to Scalic. Scalic Phrases can also contain
chords but they will be analyzed differently than chords in a Chordal Phrase. The Bass section is
automatically set to Scalic since it will rarely if ever play chords.
The terms Open and Close apply to Chordal Phrases, and refer to how the CP will regulate the
voicing of a Chordal Phrase. Setting a Section to Open will allow for open-voiced chords, which
might be good for guitar and string sounds. Setting a Section to Close maintains closed voiced
chords, which are better suited to piano parts and other chording or comping instruments.
Range
This determines the chord inversions that a Chordal Phrase will play.
The term "range" here has nothing to do with the span of actual chord notes. It selects which note
in the chord will serve as the basis of the chord inversion.
HI is the initial setting and is recommended as a starting point. MID plays an inversion based on
the next lower note in relation to HI, while LO plays an inversion based two-notes lower.
Crossover
This determines the point where a Scalic Phrase will be transposed to keep the notes in a musically
useful range. When notes in a Scalic Phrase fall below the Crossover point you select they will be
transposed up one octave by the Accompaniment System. For example if you set the Crossover
point to E, the Phrase would begin to be transposed up one octave whenever you play a chord
with an E as the root.
