The TR-09 shrinks Roland's legendary TR-909 — the drum machine that effectively invented techno and house — into the compact Boutique format, powered by the same Analog Circuit Behavior technology used across Roland's software emulations. It keeps the original's front-panel layout and workflow, so anyone who's touched a real 909 will find it immediately familiar.

A four-outlet USB audio interface separates drum voices for individual mixing, and the unit can keep playing uninterrupted while switching between modes — something the original hardware couldn't do. It runs on four AA batteries or USB power, with an included ivory DK-01 dock.
