Dly Xcple This parameter controls the amount of signal that is swapped between the left and right
channels through each feedback generation when Dly Fdbk is used. A setting of 0% has no
affect. 50% causes equal amounts of signal to be present in both channels causing the
image to collapse into a center point source. A setting of 100% causes the left and right
channels to swap each regeneration, which is also referred to as “ping-ponging”. The
regeneration affects of cross-coupling are not heard when LsrCntour is used by itself.
LsrCntour Left and Right. Controls the overall envelope shape of the laser regeneration. When set to
a high value, sounds passing through will start at a high level and slowly decay. As the
control value is reduced, it takes some time for the effect to build up before decaying.
When the Contour is set to zero, the laser portion is turned off turning regeneration into
straight feedback.
LsrSpace Left and Right. Determines the starting pitch of the descending resonance and how fast it
descends. See the section on Laser Delay for more detailed information.
Combination 4-Tap
Combination 4-Tap is a tempo based 4 tap delay with feedback used in combination algorithms.
Parameters associated with the 4 tap effect start with “4T”. The control over the feedback tap and
individual output taps is essentially the same as the 4-Tap Delay BPM algorithm, with the exception that
the delay times will pin at the maximum delay time instead of automatically cutting their times in half.
Additionally, the feedback path may also offer cross-coupling, an imager, a hipass filter, and/or a lopass
filter.

4T FB Imag This parameter controls the amount of image shifting during each feedback
regeneration. Small positive values shift the image to the right, while small
negative values shift to the left. Larger values tend to shift the image so far that
the image gets scrambled, and in some cases create ambience.
4T FB Xcpl This parameter controls the amount of signal that is swapped between the left
and right channels through each feedback regeneration. A setting of 0% has no
affect. 50% causes equal amounts of signal to be present in both channels
