Explanation of Terms
Room Reverb A simulation of the reverberation in a small room.
Hall Reverb A simulation of the reverberation in a room with a high ceiling.
Plate Reverb A simulation of a plate reverb (a reverb device which uses a metal plate), pro-
ducing bright reverberation.
Chorus An effect of enhanced spaciousness.
Flanger An effect blending sounds reminiscent of a jet ascending and descending.
Pitched Delay An effect in which the delayed sound is pitch-shifted.
Delay Feedback This term refers to when the delayed signal is returned to the input of the cir-
cuit. Delay effects marked with feedback will have more repetitions of the
delayed sound.
Panning Delay The delayed sound will be panned back and forth between the left and right
speakers (if you are listening in stereo). Even if you select a Panning Delay
marked without feedback, there will be one delay for each position of right,
center, and left.
Reverb Time This sets the length of the reverberation.
Chorus Rate This sets the modulation speed of the chorus effect. Higher settings result in
faster chorusing.
Flanger Rate This sets the modulation speed of the flanger effect. Higher settings result in
faster flanging.
Pitched Delay Pitch This sets the amount of pitch change applied to the delayed sound. Higher set-
tings result in greater pitch change.
Pitched Delay Rate This sets the modulation speed of the delayed sound. Higher settings result in
faster modulation.
Delay Time This sets the Delay time. Higher settings result in a longer delay. For the exact
Delay times, refer to the table below.
Delay Time: 0450 (msec)
The following chart shows the correspondence between Effect Time values and actual time (msec) when
Delay is the Effect Type.
