A delay line plugin, with inverted stereo / ping pong modes & a lowpass filter.

Made to be tweaked in realtime (input & feedback are ramped).

Also prevents floating point denormalization, so you will never end up with the delay line eating up 90% of your CPU.

Tip: set input & feedback to the max, set step to 1 or 3 then play with the lowpass cutoff to get a nice warm sound. Then play with panning & ping pong mode to get a cool stereo effect.
