I have reach the conclusion that the KEY is no the tool (arranger), but the player. A good arranger player can make miracles in any decent keyboard. A skill-less player can take a TOL arranger, like the T4, and produce a very poor performance.
That is a very
common conclusion.
The same could be said about guitars, trumpets, saxophones, drums, and the humble kazoo.
However, it appears, at least from the on-line demos, the performances uploaded here on SZ, and the factory presentations, that the Tyros4 is capable of a more expansive range of musical genres than, let's say, the Roland G-70, the Ketron Audya or the Korg PA-2X.
If you, or someone else, can provide examples of the Audya, G-70, and PA-2X doing
the same broad range of musical genres with the same impressive ease, it would go a very long way in showing that these instruments are
at least the equal to Tyros4 in covering an incredibly wide variety of musical genres.
Surely, if these other arrangers are
equally capable, there must be plenty of examples to illustrate this quality, although, I must admit, I have seen very little so far?
