The 96 have very few algorithms, 6 at most if memory serves me.
Some or one of them use the two engines together. These are the richest reverbs. I reckon in this mode it equates with a single engine of the 480L.
Preset 1 Big Blue uses this algorithm. Take Big Blue and tweak to suit your purpose. Try the shape and spread to achieve a faux echo, a ghostly almost repeat on vocal. I believe that's all you need to know about the 96. Lovely machine. Enjoy it.
