I love BIAB 2010 Audiophile edition. The sound is so good I'm now using it for backing tracks to play at performances. Now I find it important on some songs to make a specific bass line, where the bass line is an integral part of the song, for example Stolen Moments by Oliver Nelson. So I'm struggling too figure out how I can enter a bass line I want and keep it saved intact as part of the song. Anyone know how to do this?
