Best MIDI voice for Linkin Park - Numb

Basically, my band and I would like to play Numb by Linkin Park. I have made a small sequencer program to run on a laptop as opposed to using a MIDI instrument for various complicated reasons, which runs WAV files.
Basically, I need to know which MIDI voice sounds most like the voice used in the Numb opening, as I really can't decide.
Once I know I can then export the notes as Wavs and use the sequencer I made. Sounds like a lot of effort when I could use a midi instrument like a keyboard, but like I say, lots of complicated reasons.

Thanks,
oh and if anyone wants a copy of the sequencer, just say. I actually made it to control various piano parts for 'What I've Done'
