Convert NKI to AIFF

nki to aiff conversion seems like export of audio sample to a format playable using standard media players. It should be possible convert NI instrument samples (.nki) to standard audio files (for example AIFF - Audio Interchange File Format) with dedicated sample and instrument converters, such as Translator Professional. Standard multimedia converters unfortunately do not support professional sample files, so these cannot be used to convert nki to aiff.
