I preferred the acoustic guitar from the Yamaha. Almost everything else I preferred the Korg. Both are great though. They had the drums much hotter on the Yamaha but they sounded far better than previous models.
If they both were exactly the same, the Korg stills rules in operational features, size, weight, vocal processing and price!
Both sound incredibly well... tough i think espescially the piano´s sythsounds and strings of the korg blew the Yamaha away... I am definate sucker for the Strings and orchestral string sounds in my Kronos, and these new samples definately come from Kronos.
I disagree with you on the guitar, i prefer the more wellrounded pa4x guitar sounds in this video.
I think the yamaha drums where in a different hall then the Korg drums...but they sounded way more upfront then the Korg drums..
Sadly they didnt show the strongest features of the Tyros 5, the ensemble voices and the SA2 souds as well as it much braoder range of Euro organs...
They also didnt show the PA4x strong point, its style and overall soundquallity as a whole instrument
In the end, you cant go wrong with any of these 2...
