thanks Bane for your input,no i dont know what you mean when you say "The feel is still very natural rather than the 3D studio feel". regarding the harmonies ,i can sing harmonies a third above no problem but harmonies a third under the main melody is much harder for me,what i do is sing the main melody twice and then with variaudio i shift one of the vocals down a third but not all the notes of the new melody line will sound right so you have to shift some a semi-tone either way to make them sound right ,yes youre right i should maybe leave some out ,i will have another look. thanks
