My view is that, as the XMURE app has been around for a couple of years, if it really was the answer for arranger users then many professional players would have moved over to it by now.
One of the questions I believe, anybody relying on technology should ask, is can XMURE on an iPad provide everything I need or is a self-contained solution in a keyboard or a sound module a more reliable solution?
To me, I must have good sound quality and the possibility to program virtually any type of rhythm that I want to play.
That's a good point, LatinoMike. I, too, want very good sound quality, and many different genres of styles. I guess the best is still an arranger keyboard, even thought the prices are expensive, especially compared to software.
Thank you all for your views (you, too, Bachus):)
