You don't have to worry about infringing on any copyright laws when using arranger keyboards... The styles on arrangers are royalty free styles, and users are free to use them in any way they so choose... Look at it like this... Say you buy a sample CD that's loaded with drum loops.. You paid a specific amount of money for these loops.. These are royalty free loops, and the price you pay for using them is what you pay for the CD.. Look at it in this way with arrangers... Consider that a privilage within the price of the keyboard...
