Hi George,
Most of the time I'm converting CAVS (or Charbuster, or Top Hits Monthly) songs that I've downloaded from
www.cinet.com.
I thought at first that I was having success using a workaround of first burning the material to a CDG, ripping it back to a .CDG file and then converting the key then, but the last few times that I've tried that, it proved to be no better either.
Thanks - Gary
