I believe it is OK to use the changes freely as long as the original "Wave" melody is not included or linked to them.



That's correct - a particular set of chord changes can't be given a copyright. As mentioned elsewhere, there's a popular process of "reverse engineering" songs (usually for commercials) that are "in the style of" a particular song, but differ in enough melodic details that they're considered unique.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
