A simulation of the reverberation in a small room.
A simulation of the reverberation in a room with a high ceiling.
A simulation of a plate reverb (a reverb device which uses a metal plate), pro-
ducing bright reverberation.
An effect of enhanced spaciousness.
An effect blending sounds reminiscent of a jet ascending and descending.
An effect in which the delayed sound is pitch-shifted.
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.
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.
This sets the length of the reverberation.
This sets the modulation speed of the chorus effect. Higher settings result in
faster chorusing.
This sets the modulation speed of the flanger effect. Higher settings result in
faster flanging.
This sets the amount of pitch change applied to the delayed sound. Higher set-
tings result in greater pitch change.
This sets the modulation speed of the delayed sound. Higher settings result in
faster modulation.
This sets the Delay time. Higher settings result in a longer delay. For the exact
Delay times, refer to the table below.
