Proper sound for 4-6-4

["jktrains" <jakrueg@n...>]

I'm finally getting around to installing DCC in my Sunset 4-6-4. I 
got inspired at a recent show where a vendor had installed a sound 
decoder in an O5 with a smoke generator controlled by a second 
decoder.

My question is what soundtraxx sound decoder would be correct for a S-
4 Hudson?

Can anyone help?

Thanks,
