| Many different methods. Apply depending on the type of "fatness"
required. My examples are from DX-7, 'cause that's the only one
I have but I think most of them work for others too.
1) One operator on fixed frequency tuned below audio frequencies
(1-18 Hz) modulating others. Gives a sort of leslie effect.
2) Modulated delay i.e. chorus never fails.
3) Harmonizing (either very little difference in freq or tuned
to interval)
4) Double tracking (either with n takes on multitrk deck or with
n synthesizers). Altering the patch only slightly, for example
modulation, lfo, etc. makes the sound "deeper". Using an
alltogether different patch makes it "larger".
5) The feedback param to "7" on the DX-7 and trying to avoid
the typical FM "brightness"
6) Using a rack of 8 DX-7 modules :-) :-)
7) Making patches that hold their tightness on the lower
octaves so You can transpose them down by one or two octaves.
8) De-tuning, obviously.
9) DX-7 string pathes are good starting points for a fat analog
type sound. Lower one or two op's down by one octave, try to
get rid of the stringiness, alter the envelope more organ like
and there you are.
10) And last but not least, using an FM synth MIDIed together with
an analog one is the best usage for both.
