I rely on the one that did the recording. He thought he recorded in stereo from his Tyros2 into his laptop..besides I don't work in a recording studio every day of my life , like you..I did test on my own, and agreed with you..
This post sort of got out of context..but I still think it interesting,,I look forward to Tridents recordings of softsynths I am considering..
The postings also showed me the old can hang with the new...both sounds and people.
