The R-5 Human Rhythm Composer is an electronic drum machine introduced in 1989 by Roland Corporation, using PCM voices. The R-5 features velocity- and pressure-sensitive trigger pads, and the ability to create loops of beats. The pads are assignable and can be user defined for different sounds and also for different amplitude and semi-tones within each sample.
The R-5 is the smaller sibling of the Roland R-8 which had more sounds and features than the R-5[1]
