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: Th
is 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 process is
completely transparent; in "Analog", on the other hand, higher values, a very
loud input signal, or the sum of these will make the use of dynamics
compression audible. In both modes, the nullification of the feedback
parameter is in the center of the fader. To the right, the plug-in works in "Dual
delay" mode (both sides work independently), and to the left, "Ping pong"
mode will be activated (the delayed signal alternates between the left and right
sides).
 Mix: Regulates the mix ratio of the original signal and the delayed portion.
