What specific "tone" was used in the song "Never Forget" from Halo 3?

This song was written by Martin O'Donnell and used in the Popular XBox
360 game "Halo 3''. What I want to know is what Specific piano, e.g.
(Honky tonk, Classical, etc.) piano was used, and what the other
"tone" that sounds like a synthesizer a little bit is, and if it is or
is not, which specific type of synthesizer or what ever it is was it?
I want to know all specific "tones" that were used in the song can
anyone please provide this information if you know? Please do not say
something like "Piano" or "Synthesizer" Please say the SPECIFIC tone
used. e.g (Honky Tonk, Classic Piano, Warm pad, cool pad, etc) Thanks
SO much I learned the song completely and have every tone on earth on
my keyboard, just can't find the right ones! Its a "Casio LK-270''
keyboard and if anyone would have the specific tone number for the
tones that would also be GREAT!!! Thanks!!
