Accompaniment Track Muting; Accompaniment Volume Control - Yamaha Portatone PSR-640 Owner's Manual

Accompaniment Track Muting

The PSR-740/640 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.
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.
