Hmmm... I'm unable to make it sound like an electric organ. I have not
used it very much, so I'm not sure, but I think it is designed to
emulate pipe organs only.

Church Organ is the only pipe organ in GM. There are other
synthesizers more suitable for electric organs. Hammond (Drawbar)
Organ makes sound by an adsynth-type electromechanical device, so it
can be simulated with ZynAddSubFX (which supports addsynth) or Horgand
(another organ synth, using FM synthesis).

I'm not sure what exact instrument for Rock Organ and Percussive Organ
are supposed to be, but I think they are just variations of Hammond
(with percussion, overdrive, and different drawbars settings, i
think), so maybe can be synthesized in the same manner.

Reed Organ can be more difficult to synthesize.
