Auto Accompaniment

Accompaniment Track Muting

The PSR-550 has eight accompaniment tracks — RHYTHM SUB, RHYTHM MAIN, BASS, CHORD 1, CHORD

2, PAD, PHRASE 1 and PHRASE 2 — that you can control to modify the “orchestration” and therefore the overall

sound of the accompaniment. When a style is selected, the icons corresponding to the tracks which contain data for

any section of that style will light.

Individual accompaniment tracks can be turned OFF (muted) or ON by pressing the TRACK buttons (9 - 16)

corresponding to the target tracks. The [M] icon will appear when a track is muted. By turning the tracks OFF and

ON in different combinations, you can create various arrangements from a single accompaniment style.

Accompaniment Volume Control

This separate volume control for the auto accompaniment lets you set the optimum

level balance between the accompaniment and your right hand performance.

The accompaniment volume range is from “0” (no sound) to “127” (maximum vol-

ume).

Start the accompaniment (page 33).

Press the [ACMP/SONG VOLUME] button.

Track contents

● RHYTHM SUB, RHYTHM MAIN

These are the main rhythm tracks. The RHYTHM tracks produce

the drum and percussion sounds.

● BASS

The BASS track always plays a bass line, but the voice will

change to fit the selected style … acoustic bass, synth bass,

tuba, etc.

● CHORD 1, CHORD 2

These tracks provide the rhythmic chordal accompaniment

required by each style. You’ll find guitar, piano and other chordal

instruments here.

● PAD

This track plays long chords where necessary, using sustained instruments such as

strings, organ, choir.

● PHRASE 1, PHRASE 2

This is where the musical embellishments reside.

The PHRASE tracks are used for punchy brass stabs, arpeggiated chords and other

extras that make the accompaniment more interesting.

Adjust the Accompaniment Volume.

Use the data dial, the [+/YES] button, the [-/NO] button or the number buttons

[1]-[0].

Adjust the level as you play the keyboard with your right hand, listening to the

overall balance between the accompaniment and the keyboard-played voice.

• [ACMP] is the abbreviation of

[ACCOMPANIMENT] .
