is there any programs that are good at mixing acapellas with instrumentals?

Question

I currently use sony acid music studio but it doesnt do what i need. For those who are confused- i take acapellas to one song and mix it with an instrumental to another

Answer 1

If you do that, then you don't have ocapella anymore. That's tough. You have to coordinate the pitches, keys, dynamics and tempos. Good luck! Sorry, I am more old school than that....analog stuff.
