Not sure if it's me or if others have this problem (known or yet unknown)
If you select a Harmony for your Melody track, all is good.
If you then go and EDIT that harmony (via Harmony > Melody Harmony Select)
then the harmony is placed on the SOLOIST track (Automatically - not writing it to the Soloist track)
Then say, in my case I have a Midi part on the soloist track then it plays the Harmony.
The only way to I can find to remove it from the Soloist track is to go back to the Harmony Selection dialogue and EDIT the "No Harmony" selection (Just choosing "No Harmony" only removes it from the Melody Track.

Is this the same with others? You can test it with a "Blank/New/Empty" song. You will see the Harmony added in the "Mixer" window.
