Roland Boutique Series Synthesizer Sound Module Inspired by the TB-303 Bass Line
Bonus Item

The battery-powered Roland 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 new 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, TB-03 can send control information via MIDI or its USB port, the latter of which also functions as a 24-bit/96 kHz audio interface.

  • Realistic recreation of the iconic TB-303 Bass Line synth
  • Retains the sound, character and user interface of the original TB-303
  • Hands-on control over expressive parameters including cutoff, resonance, envelope mod, decay and accent
  • Additional features not found on the original TB-303 including four-digit LED display, overdrive and delay effects, MIDI, fine tempo control and additional functions for pattern creation

  • Continue playing a sequence even while switching between write and play modes
  • CV/gate outputs for controlling vintage analog gear and modular synthesizers
  • Dedicated trigger input to drive the internal sequencer
  • Highly portable for mobile music making
  • High-quality construction with metal front panel
  • Battery-operated (4 × AA) or USB powered

  • Built-in powered mini-speaker for instant enjoyment
  • Compatible with optional K-25m keyboard unit (sold separately)

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 Roland's acclaimed Aira series, 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.

Additional features not found on the original
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 TB-03, going from smooth to spiky to squealing. Programming patterns is also easier thanks to newly added functions that include step write, shuffle and fine tempo control. Finally, the inclusion of MIDI and USB ports mean that 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 TB-303's pattern programming method then you'll feel right at home with TB-03. The original pitch and time write modes are included along with an new 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. 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 new possibilities for live performance.

Connect with external gear
TB-03 includes MIDI in/out ports and USB, allowing control information to be exchanged with other instruments and devices. This turns 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 TB-03's internal sequencer. Once connected to a Mac or PC, 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 × AA batteries, ready for when inspiration strikes. Alternatively, TB-03 can run on USB bus power.

USB audio interface for direct recording to your DAW
Via its USB port, TB-03 functions as a high-quality 24-bit / 96 kHz 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.
