Okay. I was being dim, but realise now what you meant about input 1/2...
Lexicon Alex [chorus effect] MONO OUT > LRMSMSLR SIDE IN
LRMSMSLR LEFT OUT > 18i20 INPUT #1
LRMSMSLR RIGHT OUT > 18i20 INPUT #2
So while all the previous MS messing about was doing nothing at all, as I explained, here you have a mono chorus effect feeding only the side input of an MS decoder, so the left and right decoded outs will be identical, but in opposite polarities, and hence sound ultra wide when auditioned in stereo.
Left = Mid+Side, Right = Mid-Side, so in your case Left = chorus and right = polarity-inverted chorus.
But I do wonder if there's any normalling of the sockets on the MSLR chain, as that would make things more interesting...
