Actually, that kind of effect sound can be set up by signal routing in
any host app (or cable spaghetti on the stage floor if using
hardware):

- From the source sound channel, send signal (by an aux send knob) to
effect channel A.
- On effect channel A; open a pitch shifter and a delay set to only
wet/fx through-put. Order doesn't matter. From this effect channel,
send signal (by an aux send knob) to effect channel B (but keep effect
channel A's output going to the master sum output.
- On effect channel B; send signal (by an aux send knob) back to
effect channel A (thus creating a feedback loop that passes through
the delay and pitch shifter).

I've done this trick from the early eighties by using a rack mountable
harmonizer plus digital delay, then in a rack mountable Eventide
Eclipse as well as TC Electronix FireworX and in recent times inside
software as Logic, Ableton Live and Bidule.

Plug-ins like Expert-Sleeper's Cross Fade Loop Synth and SoundToy's
Crystallizer already include the typical signal path above.

It's more fun to set up the complete signal addressing system from
scratch, but if you decide to do that you really have to make sure the
delay unit is not set to let through dry signal - or you might fry
your ears or audio interface with in-the-box audio feedback.
