It depends on what the backing tracks are to be used for - for singers, professional CD+G karaoke tracks cannot be improved. I know - I have over 10,000 of them. For musicians who want -1, Melodyne is probably a far better tool as you can just remove the instrument you want removed from the original track. If you want to sing and play, then remove the instrument from the CD+G backing track.

A lot of professional singers poo-poo karaoke tracks but they are very happy to talk about 'half playbacks'. Frankly, they are one and the same. If you just paly the audio and do not show the lyrics on a screen, where is the difference?

RTs and RDs are great for working on your own original material and coming up with great demos or even adding a missing instrument part to an almost finished track.

Don't bother to re-invent the wheel, at least that's my motto
