■ COMPRESSOR
This effect holds down the output when the input signal from the microphone
exceeds a specified level. This is especially useful for smoothing out vocals that
have widely varying dynamics. It effectively "compresses" the signal, making soft
parts louder and loud parts softer.
• SW (Switch)
This turns the Compressor on or off.
• TH. (Threshold)
This adjusts the input level at which compression begins to be applied.
• RATIO
This adjusts the compression ratio.
• OUT
This adjusts the final output level.
■ VOCAL HARMONY CONTROL
The following parameters determine how the harmony is controlled.
• VOCODER CONTROL
The Vocal Harmony effect in Vocoder mode (page 190) is controlled by note
data—the notes you play on the keyboard and/or the notes of the song data. This
parameter lets you determine which notes are used to control the harmony.
SONG CHANNEL MUTE/PLAY
When set to "MUTE," the channel selected below (to control
Harmony) is muted (turned off) during song playback.
OFF/Channels 1–16
When set to "OFF," song data control over harmony is turned
off. When set to one of the values 1–16, note data (played
from a song on the PSR-S900 or an external MIDI sequencer)
contained on the corresponding channel is used to control the
harmony. This setting is linked to the HARMONY CH setting in
the SONG SETTING display (page 145).
KEYBOARD OFF
Keyboard control over harmony is turned off.
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 harmony.
• BAL.
This lets you set the balance between the lead vocal (your own voice) and Vocal
Harmony. Raising this value increases the volume of the Vocal Harmony and
decreases that of the lead vocal.
When this is set to L<H63 (L: Lead Vocal, H: Vocal Harmony), only the Vocal
Harmony is output; when it is set to L63>H, only the lead vocal is output.
