Donny,
You wouldn't want an open arranger with great content OOTB. Then be able to add tons of sounds (Vsti's etc, styles, as you want or need them?
Incremental growth...buy a well built machine once every ...5-8 years and upgrade CONTENT as needed..

I think it could beat the 'H' out of all this expensive spoon feeding we get from the closed arranger MFG's.
