130 Complex Echo

Multitap delay line effect consisting of 6 independent output taps and 4 independent feedback taps
PAUs: 1
Complex Echo is an elaborate delay line with 3 independent output taps per channel, 2 independent
feedback taps per channel, equal power output tap panning, feedback diffuser, and high frequency
damping. Each channel has three ouptut taps which can each be delayed up to 2600ms (2.6 sec) then
panned at the output. Feedback taps can also be delayed up to 2600ms, but both feedback channels do
slightly different things. Feedback line 1 feeds the signal back to the delay input of the same channel, while
feedback line 2 feeds the signal back to the opposite channel. Feedback line 2 may also be referred to as a
Òping-pongÓ feedback. Relative levels for each feedback line can be set with the ÒFB2/FB1>FBÓ control
where 0% only allows FB1 to be used, and 100% only allows FB2 to be used.
The diffuser sits at the beginning of the delay line, and consists of three controls. Separate left and right
Diff Dly parameters control the length that a signal is smeared from 0 to 100ms as it passes through these
diffusers. Diff Amt adjusts the smearing intensity. Short diffuser delays can diffuse the sound while large
delays can drastically alter the spectral ßavor. Setting all three diffuser parameters to 0 disables the
diffuser.
