The Prelude’s Chorus effect unit can also be used as a stereo delay unit.
These settings allow you to select chorus or delay, and the characteristics of the selected effect type.
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.

quencies, set this parameter to BY-
PASS.
