Uncountably many mutually non-isomorphic product systems (that is, continuous tensor products of Hilbert spaces) of types II₀ and III are constructed by probabilistic means (random sets and off-white noises), answering four questions of W. Arveson. Results of math.FA/0001070, math.FA/0006165 are improved, and proofs are more readable.
