Just a curiosity.
AWM2 voices have 8 elements, and FM-X parts (Montage/MODX) have 8 operators, and the organ flutes 'home' voices have 8 footages. So Yamaha clearly like having 8 things, which sounds neat to the computer-minded. But the organ flutes vintage/euro voices have 9 footages .... I wonder if Yamaha's engineers have used some kind of trick to fit 9 footages into 8 elements, or if they had to bend the model ??
Also, I recently noticed that when you have an organ flute voice selected in L, R1, R2 or R3, and you press the slider assign button, then the live control window cycles through the drawbar settings for each part in turn, in addition to the standard B/1/2 assignments. So you don't need to go through the voice set menu to get to the drawbar setup.
