Nice PR for the software, but not that big, really big news, is it? Mostly "old" updated stuff in new wrappings, or .. ?
Similiar pack(s) is also in the T4 section of the Yamaha Music Store, but this one is updated to play well and use the sounds etc. at T5.
And of course, you have to buy the expanded memory to load the stuff. In other words, business as usual.
Think I have to ask my Doctor about my ears when visit on Monday, because to me Yamaha don't manage to get rid of the CD'ish, far too perfect and a bit "cold" sound.
I.m.h.o. as a simple amateur of course, Korg and Ketron sound warmer and more natural.
