MI Elements (Omnious Mode) for FM or if you are looking for the gritty DX sound, an ALM Akemie`s. Personally I would choose the Taiko instead of the Castle.

Juno. Feedback Modules Chorus 106. Patched right behind an Atlantis.

To make chords, get a decent pitchshifter. For instance a Z-DSP with Time Fabric card.

And last but not least a sample (player) that is able to layer sounds. Load it with strings, choirs (and other "rompler" sounds) layer them and run them through a filter.

Flangers Phasers are also an important part of the sound.
