An 8 step sequencer drives the delay time. This is the matrix of red LEDs at the top. The delays are synced to host tempo. Changing the matrix values changes delay time for the given sequencer step.
A second sequencer, running at the same speed, controls the delay feedback. This is the row of 8 sliders underneath the Delay time matrix.
The sequencer has a number of features... random stepping, mulitplication and division of speed, adjustable slide (from one value to the next) and a an adjustable loop point.
The higher delay times can be tuned using the Tuning slider.
The wet signal then passes through a multimode filter, a low pass filter and a high pass filter (this allows you to really 'shape' the delay line).
Finally the dry and wet signal can be mixed as required.
There are also 2 dedicated LFOs.

A feedback delay featuring 2 frequency-warped lattice filters in the feedback paths. Lattice filter coefficients are scanned from a bitmap that can be user definable or are extracted in real-time from the input signal. Only available as a Windows VST.

Loopitch (name subject to change: suggestions accepted) is a long-period high-feeback looping machine, akin to continuous tape loops in "the old days" or digital Jam Man or Echoplex of today. Now all the Fripp and Torn wannabes out there can have fun with a MIDI controllable looper within a sequencing host!
Loopitch currently works as a DXi2 instrument under SONAR 2 (my only test platform!), and will likely play well with other DXi hosts. The VSTi version works identically via the FXpansion adapter, but is otherwise mostly untested in VST hosts.
Loopitch is considered an "instrument" (not merely an "effect"), as it needs MIDI information to control its operation: you'll need a keyboard with a sustain pedal to make it work!
Echo2005:
A Tape Echo effect
Recommended used after an amp simulator plugin
Echo2005 is a stereo input/output effect plugin
Uses 3 "tape heads" to create warm sounding echoes.
Rate and Depth controls are provieded to emulate tape flutter.
A Low Pass filter is placed in the Echo channel.
GDuckDly is a digital delay that allows the wet signal to be compressed by the dry signal.
Using high levels of feedback in a digital delay can create a busy sound. This can obscure the original, dry signal. In particular, it can make vocal tracks incomprehensible.
The compression in GDuckDly is configured so that the effect is turned down when the dry signal sounds. When the dry signal is quiet the effect is turned back up. This allows the dry signal to be heard over even extreme delay effects.
Parameters
Delay: The length of the delay.
Feedback: The level of the delayed signal that is fed back into the delay line.
Dry: The output level of the dry input signal.
Effect: The output level of the delayed signal.
Attack: The attack of the wet signal compression.
Release: The release of the wet signal compression.
Amount: The amount of compression to apply.
