I wonder how many TOTL and upper level Yamaha keboards are sold in comparison to the mid-lower end models. Although the competitors seem to be able to make 76 and 88 models, Yamaha insists on only 61. As was said earlier, I too mostly use 61 notes, but maybe 20-25% of the time want that extra octave or so. Actually, the Nord 73 is a comfortable enough fit.
