The Roland TB-3 is a modern reimagining of the iconic TB-303, the legendary bass synthesizer that defined the acid house genre. Released in 2014 as part of Roland’s AIRA series, the TB-3 combines the unmistakable sound of the original 303 with modern features and a sleek, touch-sensitive interface. After spending time with this innovative machine, I can confidently say it’s a must-have for any producer looking to capture that classic acid sound with a contemporary twist. Here’s why.
Design and Build Quality
The TB-3 features a sleek and modern design that’s both functional and visually appealing. Its compact size and lightweight build make it easy to transport, while the sturdy plastic chassis ensures durability. The touch-sensitive interface is responsive and intuitive, offering a tactile and expressive playing experience. The layout is straightforward, with dedicated controls for sound shaping, effects, and sequencing.
The build quality is solid, and the unit feels durable enough for both studio use and live performances. The TB-3 also includes a built-in speaker, which is a nice touch for quick idea generation on the go.
Sound Design and Workflow
The TB-3 is a sound designer’s dream, offering a wide range of sound design possibilities. Here’s how it shines:
- Classic 303 Sounds: The TB-3 features a wide range of classic 303 sounds, from squelchy basslines to piercing leads. The sound engine is highly versatile, allowing you to create everything from subtle textures to aggressive acid lines.
- Modern Effects: The TB-3 includes a variety of built-in effects, such as reverb, delay, distortion, and more. These effects can be applied to individual sounds or the master output, adding depth and texture to your sound.
- Touch Interface: The TB-3’s touch-sensitive interface is highly responsive and offers precise control over your sound. The interface is divided into sections for pitch, filter, envelope, and more, making it easy to tweak parameters in real time.
Sequencing and Arranging
The TB-3’s sequencer is one of its strongest features. It allows you to create patterns of up to 32 steps, with options for real-time and step recording. The motion sequencing feature lets you record knob movements and automate parameter changes, adding dynamic movement to your patterns.
The TB-3 also includes a song mode, which allows you to chain patterns together to create full tracks. This makes it a powerful tool for both sketching out ideas and producing complete songs. The ability to arrange and perform tracks directly on the hardware is a game-changer for live performers.
Connectivity and Integration
The TB-3 offers a variety of connectivity options, including:
- MIDI In/Out: Connect the TB-3 to other MIDI-compatible devices for expanded control and synchronization.
- Audio In/Out: The TB-3 features stereo audio inputs and outputs, allowing you to connect external audio sources or route audio to other gear.
- USB: Connect the TB-3 to a computer for use as a controller or to transfer projects and samples.
The TB-3 also includes two additional MIDI tracks, allowing you to control external gear and expand your sound palette. This makes it a versatile tool for both studio production and live setups.
