IMO, there will be many purchases both by pros and amatures.
I find it not that much different than entering a recording studio, and singing over a pre-recorded backing. It's the way pro singers have been cutting albums for years.
That's a good way of putting it, Larry.
The beauty of these new Wav and MP3 players, is that they can be transposed and the tempo can be changed, the latter not affecting the pitch.
I know there are other ways of doing this, but, it is nice to see it all on an arranger (including SMF, and styles), and a rather reasonably priced one at that.
And, I agree, this will be very popular to
both pros and amateurs.
