I guess every new arranger is going to get comments like what we have here. It is not different from when the T3 came out and persons were say what can you do with a T3 that you can not do with the PA2x pro? Most people believed that the T3 did not surpass the PA2x pro.
What a lot of people forget is with all of the TOTL arrangers, it is the integration of features and the types of features that are major selling points and not just the sounds and styles. If you just want sounds and styles then just use VSTs and a software arranger.
