I remembering while discussing here on keys and organs how beautiful was your Rhodes free patch for the analog Keys/Four
Organ, Keys are Based on Multiple Sinewaves, you can tricking with Triangle + Square (or Pulse) + Some intervals can help
Also, a important concept is to understand that those harmonics series are for the drawbars set, the drawbars are kind of the preset ancestors… you could add more bass to the organ sound, make it brighter / softer… But ultimately you don’t need the 9 to get the basics of the organ tone.
Although ideally going Additive with the Hammond is better, to nailed the tone… (not the extra jazz that coming with the hammond like the Leslie cabinet though…)
