Unless your entire repertoire is based around the ROM styles that come with your initial purchase of an arranger (and how many of us here are big schlager players? ), how well any arranger works for you is going to depend on two things... How much third party QUALITY styles you can get, and secondly, how easy it is to quickly edit ROM and third party styles to fine tune and create different styles.

Especially for us Americans, there are large musical areas either completely ignored or very under-represented in the style selection. Personally, I believe that this, rather than any cultural bias against arrangers, is what drives US sales so low compared to European levels. I mean, four PAGES of schlager and ONE Caribbean style? I don't know about you, but I don't use ONE schlager style. But I play a boat load (banana boat? ) of calypso, reggae and pop reggae tunes. Or same thing for country, zydeco and cajun, tejunto, folk, alternative, emo, and don't get me started about hiphop, contemporary R&B and rap

Without top notch third party support, and easy style editing tools, I would be lost trying to use an arranger. Beware of those that sound initially impressive, but have a low level of third party support, and arcane and unintuitive editing and creating tools. At least in the US, you are going to need them...

Either that, or find a schlager gig somewhere!
