As it stands the effect is really a stereo delay with separate initial delay time and feedback time for each delay. There is a switch to force it to be a ping-pong delay. The total delay buffer time is 3 seconds (at 44100Hz) for the left and right buffers (about 1.0mb total), which provides a ping pong time delay time of 1.5 seconds between left and right taps.
I have added a filter to the feedback stage so that so sound will progressively get duller(LP)/brighter(HP)/narrower(BP) with each feedback. Be careful with the resonance because with each feed back the resonant frequency gets amplified so the delay will feed back on itself. You can bypass the filter section (and save CPU) by setting the filter type to Thru.
Echomania:
Besides being a CPU hog this plug-in goes further than most (all?) real tape delay machines. It's capable of stereo delays, ping pong delays, multitap delays and complex delay textures.
tape model including tape saturation, tape noise, flutter, low and high pass filtering
4 separate delay lines which can be configured for various delay types (Try out the preset programs as examples. Also see the included signal diagram "diagram.jpg" to understand the structure of this effect)
delay times can either be defined in milliseconds or in relation to the song tempo in your sequencer. (switchable for each delay line)
all parameters are controllable by midi controllers.
pop-up hints help to understand the function of each control on the user interface. These appear when the mouse rests over a control.
Also the assignement of midi controllers is documented in the pop-up hints.

Stereo dual delay with lowpass resonant filter.
Another incredible free plugin, maybe the ultimate stereo delay out there. Powerful and easy to use, its main features are:
2 independant left/right delays with delay and feedback controls,
Lowpass (-24 dB/Oct) resonant filter,
Delay times can be expressed in ms or in 16th notes (when synced to the host tempo),
Group mode for ping-pong delay effects.

GRevDly is a delay effect I wrote to give an eerie feel to an intro for a song. It plays the delayed signal in reverse. Reversed chunks are cross-faded to eliminate clicks - the overlap parameter controls the length of the fade.
Retro Delay is a flexible allround delay effect in VST format.
It has the character and sound of a vintage delay unit but features many modern options.
Besides delays, it can produce a wide range of modulation, chorus, flanger and phaser effects.
