Nylon guitar sound

[tramway]

Hi.
I've recently bought Ilya Efimov's Nylon Guitar, have opened it in Kontakt today and played with my USB-MIDI cable with synthesizer keyboard, but the sound is far from the demos.
Must I use any additional effects or plugins to get the sound close to the demos or it can be reached only in this guitar settings (reverb etc.)?
Are there any hot keys to use different articulations in real time on keyboard?
The sound is rather flat.
Also waiting for MIDI with all instruments and possibility of hearing demo in Android.
