FTA: There are some interesting designs here - and they work, but they often require careful tuning. As well as finding a good compromise for the delay time, using too much inter-channel mixing can lock the delays together so they act like a cohesive unit, which isn't great for longer tails. Made me wonder whether there’s a connection with linear feedback shift registers (https://en.wikipedia.org/wiki/Linear-feedback_shift_register https://en.wikipedia.org/wiki/Linear-feedback_shift_register) If you have a LFSR that produces a decent but not too good pseudo-random signal, can you use its parameters to create a decent reverb?
