For sure, if someone misunderstands this (I quote "It was done on a Tyros 4") and thinks this soundtrack can sound like that with the Tyros voices, it could be quite annoying and misleading. If it's just about enjoying music, no problem, but I suspect it contributes to give misleading impressions of what a Tyros is capable of. These natural sounding strings are certainly gigabyte strings from East West and no Tyros strings, etc.
