I have to say that I do agree with DIKI on this silly idea.It's a nice tool for some stuff, but to actually perform that way there is really no point.Just put on a CD and you might as well pretend you are playing too.And I do love new technology and new stuff.
Just imagine doing just a simple wedding. Doesn't have to be anything high profile gig.Imagine people faces when they see you are not singing.To tell you the truth,where I come from I can't even imagine having DJ for a wedding.Anything short of a live music is not even a question.That is a first thing people ask."Who is Playing".And the wedding is only good if the music and party is good.Everything else(flowers,food...etc..)is going to be good if the music is good.
