Ita just marketing talk...
The pa4x is just as much workstation as arranger
- workstation is a concept..
- auto accompaniment is a feature
- arranger is any keyboard with auto accompaniment on board..
Its just a thin line..
In general its better to just compare features between keyboards
The labeling them in cattegories?
Great points. It is interesting to note how often we are influenced and "conditioned" to think in a certain way by marketing and for that matter anything else.
