One of the reasons why some people just don’t get the value of the MS is that they are applying the wrong standard to the arranger section of the MS.

The standard is not whether it “sounds” better than a T3/PA2xpro, (what ever that means because that is very very subjective) but it is whether the user can customize the arranger section to his or her playing style and gigging market.
And once you customize the arranger section to your needs, then you can integrate other sections of the MS to work seamlessly on your gig.

There is a reason why it is called a “Media Station”.

Really it is for those who incorporate covers and originals, styles, mp3s, midi files, audio, video and midi on their gig.
Integration can not be overstated when we talk about the MS.

So that some people can understand the concept of Integration, take for example some one who use to use a keyboard and a drum machine. Now, instead of having both a keyboard and a drum machine, they can have it all in one with some more features in the form of an arranger.

Lets say he got a T3. Do you think that person is going to go back to the keyboard and drum machine because the Yamaha T3 drums suck?
