The Hammond partials are square waves, altough on my JV80 the square is too synthy
so I used a sine wave. You can emulate the drawbars by making on single sine wave sound
and then use a performance and then transpose the different parts and then your sliders when assigned to part level will be drawbars. Iff you want a mid-file of a performance for JV80 (Your XP should be able to read it) mail me.
