George, Thanks for your good wishes.
I actually had to use a file with the key changed up at an affair in which I was to sing "Top of the World". I was noticing the little "Pop" but was going to live with it. That morning I decided to take some time and make an MP3-G of the file, convert the mp3 part to wave, use Nero to change the key, change it back to mp3, convert the mp3-g to Bin then back to normal cdg (Whew-I'm out of breath) No "pop" in an original cdg, but obviously a lot of extra work.
So I do have the workaround. Obviously the workaround is less if I am creating the files with KHPRO. I haven't tried wave files on Keyrite recently. But if Keyrite can't do the cdg files, then it's not very useful.
But like I have said already. The downward keychanges don't seem to have this problem.
