Built with a detailed Matrix display, MIDI in/out, DIN syn capability and individual drum tone outputs, the Roland TR-707 Rhythm Composer is an overlooked gem of a drum machine. Frequently said to capture many of the snare, bass, and hi-hat sounds of its more expensive brother, the TR-909, the TR-707 encapsulates the quintessence of '80s drum programming without crushing your wallet. Used by artists ranging from Phil Collins to Aphex Twin, this drum machine could be the next sleeper hit for your electronic setup.
