• Mix: This regulates the ratio of the unprocessed signal to the portion
including reverberation.
Stereo delay
The stereo delay is a simple too for typical bread and butter delay
effects. The "analog algorithm" qualifies as a special feature that
produces the sound of echo devices from the old days.
Stereo delay parameters
• Mode: This selects between the essential algorithms.
• Digital: Normal, transparent delay
• Analog: Simulation of a bucket brigade delay (BBD). These devices,
which originate from the pre-digital era, used analog building blocks
for storage. The signal was held for a short time in a relatively simple
circuit and then moved on to the next. This "bucket brigade"
principle created a longer signal delay. But since each element of the
chain led to a loss of the signal and would increase the system noise
with longer delays, the devices would use a compander: At the
input, the signal's dynamics are compressed, and then they are
expanded again at the output end. The simulation in the eFX delay
mimics the loss and compander behavior to produce these typical
audio characteristics, especially at longer delay periods and higher
repetition rates (feedback).
• Delay L/Delay R: Specify the delay period for the left and right
channels here.
• Tempo sync: If this button is active, the plug-in is directed at the
host/sequencer tempo. In this mode, changes are made to the delay
period via the L/R delay using the musical snap grid (e.g. 1/4 note).
• Damping: This specifies the cut-off frequency at which the highs are
dampened during the delay. This useful for making the delays
reverberate more naturally or for creating special effects
(reggae/dub-style effects).
• Feedback: This parameter regulates the internal amplitude of the
delayed signal that is fed back to the input. In "Digital" mode, this
