14 stereo diffusers in series, then low-pass filters and VCA, and then cross-connected to the opposite channel. Taps from mid-way along the diffuser chains are mixed with the final output of the chain and fed into a mix balancer.

Value controls are provided for Delay time, Low-Pass Filter Cutoff, Output (Wet/Dry) Mix, and the cross-channel feedback.

(The CPU loading is close to the max. There is also a 15 diffuser version. You may still want to remove one of the diffusers if you are using too much CPU!)
