Ray, that offer is for new customers, and sadly, excludes existing customers who opt to upgrade.
That is the subject being commented on in this thread. Many of us read the ad with the same thought.
And I am not Jim, but will offer my opinion on the Nashville EZX. I would rate it as "good" with one caveat.
If you want project ready drum tracks that are what I would say are "good enough" its a good expansion for you. If however, you are the kind of producer who likes to finely taylor your drum sounds to fit your projects, you may find as I did, that the samples are pretty heavily processed with what I find is often excessive amounts of reverb. I prefer working with somewhat drier drums to my tastes. Thats not to say they arent useable, just something you may want to be aware of.
And I'll agree with all of Jim's points. Especially the need for some improved descriptions. Many of the EZX and MIDI expansion descriptions are vague as to what exactly is included IMO.
