PSR-S970/S770 Reference Manual
VOCODER The Vocal Harmony effect in the Vocoder and Vocoder-Mono modes is
CONTROL controlled by the notes you play on the keyboard and/or Song data.
When set to "MUTE," the channel selected below (to control Harmony)
CHANNEL is muted (turned off) during Song playback. This enables you to sing a
MUTE/PLAY song with harmony, even without backing or accompaniment.
When set to OFF, Song playback does not affect the Vocal Harmony.
CHANNEL When set to one of the values 1–16, note data (played from a Song on
OFF/1–16 this instrument or external MIDI sequencer) contained on the corre-
sponding channel is used to control the harmony.
KEYBOARD OFF: Keyboard performance does not affect the Vocal Harmony.
UPPER: Notes played to the right of the Split Point control the har-
mony.
LOWER: Notes played to the left of the Split Point control the har-
mony.
The separate point of the Keyboard settings (OFF/UPPER/LOWER) is Split Point (LEFT).
NOTE
When the settings of both keyboard performance and Song data are applied, those settings are
NOTE
merged to control the harmony.
CHORD In Chordal mode, the following parameters determine which data in a
Song is used for chord detection.
OFF: Chords are not detected from the Song data.
XF: Chords of XF format are used for the Vocal Harmony.
1–16: Chords are detected from note data in the specified Song chan-
nel.
The Vocal Harmony may not work properly regardless of the setting here depending on the Song
NOTE
data, since the selected Song may contain no chord data or insufficient note data for chord
detection.
