Mitch Gallagher visits Six01 Studios for Roland's 909 Day, and is joined by product specialist Peter Brown to demonstrate the TR-09 Rhythm Composer. The original Roland TR-909 provided analog kick, snare, and toms, along with 6-bit samples for hats and cymbals. This hybrid sound-generation method ensured that the '909 sounded like no other drum machine. So it's cool that Roland has brought this classic back in updated fashion for their Boutique series. The Roland TR-09 Rhythm Composer is powered by Roland's cutting-edge Analog Circuit Behavior (ACB) technology, and it delivers the speaker-punishing grooves you know and love, along with modern enhancements. The TR-09 gives you exacting control over a selection of drum parameters and now lets you keep playing while switching modes. Other new features include USB audio with four separate outputs, external device control via a trigger output, and USB MIDI.
