Hi Peter, the MIX feature is a great tool to exit a song and professionally mix to the NEXT song, this button is needed at all times on all devices, but you already know that, my other suggestion is to improve its great function for on stage is if you have a number of audio regions in one file like a compilation mix it would be great if you choose a new region within that file and then you use MIX button it should then assume the next thing you want is a MIX to that region and not the NEXT selected song , once the new region has been mixed to and there is no more regions selected then the MIX button logic goes back to NEXT song .
This would give us great flexibility to manoeuvre around a 24 segmented song as well as all the songs in our library , I would also make it if you select the NEXT song the interface shows you the waveform only NOT the Lyrics as they are still in use as the song is playing with audio segments of the NEXT SONG so you can MIX from one SONG to another SONG AUDIO SEGMENT, this capability would greatly improve the on stage control if you are a SOLO Performer or especially a DJ that just plays tracks as that would keep the VIBE GOING ON THE DANCE FLOOR as needed and not as PRE PLANNED as we all know you can plan as much as you like but it’s always different every gig.
