Featuring a user-friendly four-digit LED display, onboard distortion and delay effects, and versatile connectivity including MIDI, USB audio interface, and CV/Gate outputs, it’s designed for both studio precision and mobile music-making. Lightweight with a metal front panel, it preserves classic sequencing with modern enhancements, making it a must-have for producers craving that legendary acid bassline sound. ## Description From the manufacturer Modern recreation of the iconic silver box defined the acid house movement of the late 1980s THE CLASSIC TB-303 SOUND IN THE PALM OF YOUR HAND The battery-powered TB-03 is a direct descendant of the famous TB-303 Bass Line Synth. The layout and controls are unchanged, so it works just like the original. It sounds like it too, thanks to Roland’s advanced ACB technology that recreates the hypnotic liquid grooves of the magic silver box. But the TB-03 goes even further, with several enhancements not found on the original model. The four-digit LED display makes programming easier and more accurate, while overdrive and delay effects let you unleash a twisted, tribal wall of sound to send the crowd into a frenzy. Back in the studio, the TB-03 can send control information via MIDI or its USB port, the latter of which also functions as a audio interface. The Roland TB-303 was a machine like no other Widely misunderstood when launched in 1981, the true revolution began several years later when electronic music producers rediscovered the 303, unleashing the hypnotic, liquid sound that captivated a generation. While we may never really understand why the 303 makes people dance, there’s no denying its power, influence and ability to get a party started. It just works, even after all this time. Get the rave started Realistic recreation of the iconic TB-303 Brought up to date with modern features Built-in powered mini-speaker and headphone jack MIDI IN/OUT and USB Highly portable for mobile music making High-quality construction with metal front panel USB data backup function Compatible with optional K-25m Keyboard Unit Authentic 303 Sound and Behavior via Roland’s ACB Technology You know when you hear a TB-303—a hypnotic, tribal sound that works best in dark, crowded rooms with big sound systems. Using the same ACB (Analog Circuit Behavior) technology from the acclaimed AIRA series, the TB-03 accurately emulates the expressive, slippery sound of its older brother, and even adds a few surprises. Saw and square waveforms are available, along with all of the rotary control knobs that help shape the 303’s unique character, including tuning, cutoff, resonance, envelop mod, decay, and accent. Advanced Features Not Found in the Original The TB-03 includes several enhancements over the original TB-303. Firstly, the four-digit LED display makes programming easier and more detailed, since you now have a visual representation of the value being edited. Then there are a variety of overdrive, delay, and reverb effects that dramatically change the mood and tone of the TB-03, going from smooth to spiky to squealing. Programming patterns is also easier thanks to added functions that include step write, shuffle, and fine tempo control. Finally, the inclusion of MIDI and USB ports mean that the TB-03 can send and receive control information and connect easily to computer-based DAWs. Classic TB Sequencer with Enhanced Functions If you’re familiar with the TB-303’s programming method, then you’ll feel right at home with the TB-03. The original Pitch and Time write modes are included, along with an easy Step mode. Pattern programming is also enhanced by the LED display, which shows the current step in the sequence as well as showing fine tempo values (such as 125.5 BPM). The internal sequencer can be triggered externally via the trigger input, and you can even switch between write and play modes without stopping pattern playback, opening up amazing possibilities for live performance. Connect with External gear The TB-03 includes MIDI IN/OUT ports and USB, allowing control information to be exchanged with other instruments and devices. This turns the TB-03 into a versatile controller, especially as you can use the CV/Gate output to control external analog gear and modular synthesizers. This level of control works both ways, thanks to the trigger input that lets external gear drive the TB-03’s internal sequencer. Once connected to a PC or Mac, both audio and MIDI data can be sent through the USB port. Battery or USB Bus Power Some of the best music is made away from the studio, so the Roland Boutique series runs on 4 x AA batteries, ready for when inspiration strikes. Alternatively, the TB-03 can run on USB bus power. USB Audio Interface for Direct Recording to Your DAW Via its USB port, the TB-03 functions as a high-quality audio interface, providing a simple and reliable way of recording directly to your DAW application. You can keep your favorite settings and sequencer patterns safe too via the USB data backup function.
