Hi Vos
Under ableton live there are scenes for each songs that contains sound clips (audio tracks) and midi tracks, and the way I work is to setup four midi tracks which correspond to the four tracks on the A4, and sometimes the tracks are midi sequenced or being played by hand during live performances depends on the song. So I can have a scene for each song (scene also contains bpm information) it also means there are a lot of program switch to do during song changes, but i found it awesome that I can use A4 for this kind of setup especially it has 4 tracks can be played at the same time ^^
