The Yamaha RM1x is a groovebox manufactured by Yamaha from 1999 to 2002. It integrates several, commonly separate, pieces of music composition and performance hardware into a single unit: a step-programmable drum machine, a synthesizer, a music sequencer, and a control surface.
The front panel of the RM1x is angled slightly to facilitate tabletop use but Yamaha also produced an accessory to allow rack-mounting the unit.
The RM1x is organized into five blocks: sequencer block, tone generator block, controller block, effect block, and arpeggio block.
