The RM50 is a rackmount drum module version of the Yamaha RY30 drum machine. It uses AWM2 samples in ROM for sound generation. It is the percussion counterpart to the Yamaha TG500 and has the same front panel design.
It has six drum trigger inputs, allowing it to be used as a MIDI drum module, or as the brain of an electronic drum kit. It also has 3 wave card expansion slots for expansion cards from the RY30, SY77, and SY55 synthesizer. A fourth RAM card slot allows saving an additional 500 variations, 100 patterns, and 64 drum kits.
