Cutoff (Cutoff Frequency)

Sets the cutoff frequency when a specific frequency band is cut off by a filter.

Step Rate (Step Rate Switch/Step Rate #)

Adjust the frequency of pitch change.

This setting determines whether the pitch is changed in a stepped fashion (ON) or not (OFF).

Step Rate parameter can be set as a note-value of a specified tempo. In this case, specify the value of the desired note.

When Step Rate is Set as a Note Value

As the specified tempo, you may use either the Patch Tempo (p. 71) or the tempo clock of the XV-88’s system (p. 169).

Keysync (Keysync Switch)

Determines whether the Flanger LFO is reset according to the input sound (ON) or not (OFF).

Thre (Keysync Threshold)

Adjust the volume level for which reset will be applied.

Keysync Phase

Sets the LFO phase when the LFO is reset.

LowGain (Low Gain)

Adjust the low frequency range gain (amount of boost or cut).

Positive (+) settings will emphasize (boost) the low frequency range.

Hi Gain (High Gain)

Adjust the high frequency gain (amount of boost or cut). Positive (+) settings will emphasize (boost) the high frequency range.

Balance #

Adjusts the volume balance between the direct sound and the flanger sound.

With a setting of D100:0W only the direct sound will be output, and with a setting of D0:100W the flanger sound will be output.

Level (Output Level)

Adjust the output level.

Drive #

Turns Drive on/off.

Specifies the depth of distortion. The volume will change together with the degree of distortion.

Vowel

Selects the vowel. The left setting is the vowel 1. The right setting is the vowel 2.

Rate #

Sets the frequency at which the two vowels will be switched.

Rate parameter can be set as a note-value of a specified tempo. In this case, specify the value of the desired note.

When Rate is Set as a Note Value

As the specified tempo, you may use either the Patch Tempo (p. 71) or the tempo clock of the XV-88’s system (p. 169).

Depth #

Sets the effect depth.

Keysync (KeySync Switch)

Determines whether the LFO for switching the vowels is reset according to the input sound (ON) or not (OFF).

Threshold (Keysync Threshold)

Specifies the volume level for which reset will be applied.

Manual #

Sets the point at which the two vowels will be switched. When set to 50, Vowels 1 and 2 switched in the same amount of time. Setting this higher than 50 increases the time for Vowel 1; setting this lower than 50 decreases the time for Vowel 1.
