ok -- if there is a strong case for not wanting to break old things --

BUT with rand it will just be a different algorthm -- still be "random"--
so if anything things just might sound "different" and if you have specific
sound you want you have ability to revert back to old..

the optional flag will only be used to revert back to old so for most people/
orcs it will be not noticable change
