Only a few are .sf2 but if you have access to a PC, you can grab the others and convert them. There are MP3 demos.
The drums do come as .wav files and there are options for battery and GigaStudio.
Here's info on the drumkit.
The drumkit (ns_kit) is 68MB compressed and opens out to 198MB.
Recorded direct to disk at 24bit/96KHz Dithered down to 16 bit, 44.1KHz for this free version Recorded as a drum-kit - e.g. when you hit the toms, the snare resonates.
Version 7 of the ns_kit series represents a whole new level of quality, playability and realism.
• 321 all new stereo samples
• even longer decays.
• more velocity layers per instrument
• more cymbals
• a slightly more ambient sound results in a kit that simply sits better in a mix.
• A more “generic” sounding kit – suitable for most styles
• Snare “buzz-roll” samples allows dynamic playing of snare rolls.
