Product Description
Reimagine iconic electronic basslines while driving modern beat production with hands-on control. The Roland TB-3 Touch Bassline is a performance-ready touch pad bass synthesizer built upon the legendary legacy of the classic TB-303. Designed specifically for intermediate performers, electronic music producers, and sound designers, this compact AIRA module combines classic analog mojo with modern digital playability for studio tracking and live electronic sets.
At the heart of the TB-3 is Roland's proprietary ACB modeling technology (Analog Circuit Behavior), faithfully reproducing every sonic nuance, resonance, and slide behavior of the original vintage circuitry. The instrument comes packed with 134 high-octane sounds, ranging from authentic vintage 303 square and saw waves to aggressive modern synth bass patches, distorted leads, and sound effects. Outfitted with a bright pressure-sensitive touch pad controller, users can play notes, adjust volume, and tweak filter cutoff frequencies seamlessly using intuitive finger gestures.
Designed for fluid workflow and live stage improvisation, the built-in 16-step sequencer features dedicated step and real-time recording modes alongside slide, accent, and pattern shuffle controls. The signature Scatter wheel adds instant slice, reverse, and glitch effects to keep beats evolving dynamically during performance. Complete with USB audio/MIDI connectivity, MIDI I/O, and external clock sync, this lightweight bass synthesizer module integrates effortlessly into hardware synth rigs or computer-based DAWs for continuous music creation.
