That's an interesting point about editing/modifying styles, Ian.

In legal terms, I wonder at what point is an edited/modified style regarded as not being the original work. I suppose it could be argued that changing even one note or beat might be deemed enough to render the edited/modified style different enough as to not infringe any copyright restrictions.

In buying an arranger the costs of original style creation are obviously included in the purchase price, yet the manufacturer includes the facility to edit/modify those styles which, presumably, having been edited/modified by the purchaser, are no longer classed as original and can be freely distributed.

Fascinatin' ain't it? Any copyright/intellectual property lawyers on here?
