Hammond organs used a series of sine waves. A common drawbar stting would be 888000000. That means the first three drawbars were pulled out. If you set scene 1 osc 1 pitch to 0 and edge to 0 you get close to the first drawbar. The 2nd drawbar would be osc 2 pitch set to 12 edge=0. Then the 3rd drawbar, go to scene 2 set osc 1 pitch to 19 and edge to 0. Envelope attack around 3 decay 120 sustain 120 release around 3. Youi could set attack and release at 0 but I get a clicking when I do that.Set layer to dual. Get a nice sound.
also try scene 2 osc 2 at 24 or 36.
Also try setting pmod depth to around 2 to -2 on the oscillators for vibrato.
