You've got a habit of revealing something different that you are doing after having asked the question.

Having no Crystal Ball abilities, we can only answer a question based upon the information given and here the assumption when you say, "parts of songs manually for live performance" would naturally lead anyone attempting to help to think that would mean a Band in a Box format song.

Audio tracks, without any BiaB autoaccompaniment?

I wouldn't know, have never tried it that way.

Seems like you have already found your answer though.
