Some times there is some 'lost in space' chord to be found some where beyond the 'end' bar, usually the result of arrangement changes and copying/pasting or switching on/of 'tag exists' or '2-bar ending'. I found it some times rewarding before exporting wavs and midis, it to be useful to select a lot of bars in the 'greyed out' arrangement window beyond the end, and just press 'delete'. F
