My 2 Cents...

First, the comparison on the Organs sounds, totally wrong, the T4 only has, per say, has the "Vintage" a.k.a. Hammond, and the T5 has the same only that the person that made the demo, choose for the T5 the "Home" organ out of the Euro, Vintage, Theatre and Classical....Not the same Vintage organ sound...that is also part the New Section Organ World on the T5.

Second, the S.A.2 Jazz Sax sound on the T4 also is also found on the T5, but the person doing the demo choose a totally different sound, the New S.A, Tenor Sax sound....that actually is the S.A. 2 Tenor Sax found on one of the Premium packs...!!!
I happen to have it also on the T4 that is of course, optional.

The T5 S.A. 2 Tenor Sax will have other characteristics, like Growl, etc. VERY different than the one "represented" [/b]on the T4.

Again, on the T4 the Sweet Muted trumpet is also found on the T5, but the T5 has the NEW S.A.2 Muted Trumpet was chosen....why not compare them with the same sounds?, if purposely choose other sounds even within the same family sounds,
it is not a accurate representation at all.

Like comparing a Baritone sax on one Keyboard and a soprano sax in the other....

They maybe on the same family, but the sound of each is totally different.

As a T4 and T5 owner, this video to me, is not representing fairly either model.
I know what I am talking about.

On the Styles the same, one has Midi Based styles T4, and on the T5 (all the T4 styles are also included),it has[b][/b] the New Audio Styles....so, is apples vs pears????or perhaps bananas?
