Note that when you select any of the voice presets (voice numbers) as the Main Voice, the keyboard is programmed to automatically select certain default settings that Yamaha feels go well with that voice-- the Volume, Pan, Reverb Depth, Chorus Depth, Dual Voice Number (even if the Dual Voice is turned off for that preset), the Dual Voice settings, the Reverb Type, the Chorus Type, the Harmony or Arpeggio parameters, etc.
Consequently, if Fantomas isn't selecting a specific Reverb Type and a specific Chorus Type after choosing the voice, then he is using the default types. Yamaha occasionally changes these default parameters from model to model, but usually they're the same from one model to the next-- although the default Volume might be set a bit differently. So if you choose the "Reso Str" voice, then select the settings he indicated to the values he listed, you should get the same results as him.
