I use BIAB for songwriting. I´ve tried almost all there is on the market, but this is what suits me best. I lay down the chords in BIAB using an external keyboard - Axiom 49 pro - and instead of typing I hold down the pianokeys and CMD-Enter them in. I usually only want the guitars, piano and bass, muting the rest. Then using the DAW Mode, I drag a Combo file to iTunes and transfer it into VocaLive getting a stereomix on track four. Then I start trying out the melody using nonsense lyrics, sometimes even adding three-part harmony choir. Sounding something like THIS.
