Description
Selects either Chorus or Delay.
0 (OFF): Neither Chorus or Delay is
used.
1 (CHORUS): Chorus is used.
2 (DELAY): Delay is used.
3 (GM2 CHORUS): GM2 Chorus is
used.
Type of filter
OFF: no filter is used
LPF: cuts the frequency range above
the Cutoff Freq
HPF: cuts the frequency range be-
low the Cutoff Freq
Basic frequency of the filter
Adjusts the delay time from the direct
sound until the chorus sound is heard.
Frequency of modulation
Depth of modulation
Spatial spread of the sound
Adjusts the amount of the chorus sound
that is fed back into the effect.
Adjusts the delay time from the direct
sound until the delay sound is heard.
Adjusts the proportion of the delay
sound that is fed back into the effect.
Negative (-) settings will invert the
phase.
Adjusts the frequency above which
sound fed back to the effect will be cut.
If you do not want to cut the high fre-
quencies, set this parameter to BY-
PASS.
Volume of each delay sound
Cuts the high frequency range of the
sound coming into the chorus.
Higher values will cut more of the
high frequencies.
Volume of the chorus sound
Adjusts the amount of the chorus sound
that is fed back into the effect.
Adjusts the delay time from the direct
sound until the chorus sound is heard.
Frequency of modulation
Depth of modulation
Adjusts the amount of chorus sound that
will be sent to the reverb.
If you specify the delay time as a note value, slowing down the
tempo will not change the delay time beyond a certain length.
This is because there is an upper limit for the delay time; if the
delay time is specified as a note value and you slow down the
tempo until this upper limit is reached, the delay time cannot
change any further. This upper limit is the maximum value that
can be specified when setting the delay time as a numerical
value.
