This particular example, hand carved in Peru, was the very one used in "Across the Andes by Frog". Recorded in situ in the steamy jungle of my music room, in macro-stereo with a matched pair of studio condensers in an x-y pattern.
A wide selection of sounds were recorded at different velocity levels, with alternate sounds triggered in round-robin fashion, for a very expressive instrument (over 40 samples), going all the way from the frog's natural range to a pitched-down bass thud.
The Kontakt script has knobs for tuning the sounds, and the mod-wheel brings in an impulse reverb which echoes away like the seven thousand rock islands of Lake Quequeña. The reverb is based on an impulse made by my very own acoustic-space modelling program, and is not available anywhere else.
The impulse alone is worth the price of the whole kit!
