Rumble by Sample Logic and System Blue, is a virtual instrument that specializes on traditional marching drums and allows for morphed drum sounds.

Rumble contains a comprehensive set of carefully crafted traditional marching drum samples. Each of these instruments were captured using film music recording techniques, giving it a cinematic touch. They are recorded at multiple dynamic levels, variable microphone positions and which allows for more dynamic musical percussive productions. These sound samples are also used as the basis for other morphed sounds that are made available.

The library contains both traditional instruments and a collection of tweaked “cinematic” instruments, which mostly aims to satisfy the musical scoring needs of film, TV, electronic music composers and games.
