Product Description
Alesis SR18 Advanced Drum Machine — Powerful Portable Rhythm & Bass Workstation
The Alesis SR18 is a feature-packed drum machine designed for musicians, producers, and performers who need realistic drum grooves, electronic beats, and bass parts in one portable unit. Loaded with over 500 drum and percussion sounds plus 50 bass sounds, the SR18 handles everything from hip-hop and EDM to rock, country, and pop with ease.
Alesis’ exclusive Dynamic Articulation™ technology allows samples to evolve as you play, responding not only to velocity but also with natural tonal and timbral changes—just like acoustic instruments. The onboard Alesis effects engine provides studio-quality reverb, EQ, and compression, delivering polished, performance-ready sound straight from the outputs.
The SR18 goes beyond traditional drum machines by allowing you to plug in a guitar or instrument directly, jam along instantly, or program bass parts using the pads or an external MIDI keyboard. With both AC and battery operation, it’s equally at home in the studio, on stage, or on the road.
