I understand most of us use ArrKBs as a "Live Performance tool". But I still do enjoy now and then a "creative minute" when I just do track recording. I think the 9000 is just excellent for ease of use in this... How many of you regularly use this feature? Comments? Clever Tricks and else...? How do you change the volume within a single track in the song, if you do not have a vol pedal? Can you do this in the edit phase?
