BL-303 is a synthesizer inspired by the iconic Roland TB-303, designed to bring the classic acid basslines, leads, and sequences into your music production with ease. This instrument captures the distinctive character and sound that made the original synth legendary, allowing producers to recreate that unmistakable acid house vibe effortlessly.

The latest version offers a refined and resizable user interface for improved workflow, alongside a carefully fine-tuned filter that closely emulates the behavior and tonal qualities of the original TB-303. Additional enhancements include various sound and performance optimizations, plus native compatibility with both macOS ARM and Intel processors, making it accessible across a wide range of modern setups.

Sequencing in BL-303 is controlled via MIDI note velocity, providing intuitive management of the slide and accent features integral to the acid sound. By adjusting note length and velocity, you can trigger slide effects and accents with precision, offering dynamic control that mirrors the original hardware's expressive sequencing capabilities.
