An arranger is a keyboard that allows the user to play chords in the left hand and get other sounds to automatically play and follow the chords (primarily drums, bass piano/guitar and so on) while at the same time allowing the user to play a melody or chord in the right hand.

That is the basic feature of an arranger, and with out that ability can not be called an arranger or said to have arranger qualities.


Now, some keyboards may have additional features like 1 2 3 or 4 variations, 1 2 3 or 4 fills intros or endings, different chord recognition tables, and most have styles coming from the factory.


There are some keyboards that are strictly arrangers and can not do any thing else like the Yamaha T3 and PSR s 900. While there are other arrangers that are both arrangers and workstations like Korg PA2x and the Gem Genesys.


Now the mediastation is taking it a step further where it is not just an arranger, it is not just a workstation, but can play and used VSTs and audio files.

In no way shape or form can the MS be classified to be just an arranger like the Yamaha PSR S900. In no way shape or form can the MS be classified to be a workstation like the Roland G nor can the MS be classified to be just a DAW, software arranger or synth, but it is a hybrid of these three different types of music making tools.


Regardless of the amount and quality of the content shipped with the product, it does not change what it is or whether it can function as an arranger, workstation or a DAW/software synth arranger.
