Arrangers are primarily voiced and set up in the UK, Germany & Japan (The US has little (If any) input into them) due to the fact that arranger sales in the US are miniscule compared to Europe and Asia.

Also Arrangers have always been designed for the Home User first, with the Pro player way down the scale, (Manufactures assume that all Pros will use Workstations not arrangers) this is why arrangers sound great in the home, but need a lot of work when put in a gigging situation.

In addition most countries produce their own styles & pre-sets etc. for their particular type of music, whereas the US produces little. (Even though US users complain that arrangers sound too European)
