The basic concept is having separately MIDI controled FM operators.
One is made to play a single note, the other melodic stuff tuned to
result in good-sounding FM.
A third operator thrown in for more complex attack phases.

It's one patch with 3 MIDI inputs. 2 of them control FM operator
subpatches. The 3rd is used to trigger 2 things via different notes:
a sine-based kick used as influence to one operator, and a feedback
loop on an AmpV plugin.

There's also some delay applied for retriggering envelopes.

It's actualy quite a mess, so following Loki's request, I put the
the patches with the MusE song and MIDI export up at
http://thorwil.affenbande.org/fm_casserole.tar.bz2  (28.8 KB)

Sadly it will only work with one specific patched CVS version of Om, 
which you can get at
Just don't ask Dave for any support. Actualy, best leave him alone
until next release ;)
The current SVN version of Ingen might be able to load the patches
so you can at least look at the structure, though.
