There is only one file type that uses the .KT2 extension:
Battery 2 Drum Kit File
File used by Battery, a program that creates drum rhythms and sounds from drum audio samples; contains descriptions and sound samples a particular drum kit type, such as a Rock Kit or Jazz Kit; includes kit sound samples for bass drum, snare drum, hi-hats, percussion, toms, and cymbals.
KT2 files have been replaced by newer .KT3 files.
