## Description

2XB303 Acid Bass Loop Maker is a creative bass synth sequencer that lets you craft electro melodies and acid techno basslines with a live control interface. It supports triggering and transposing both sequences, plus a built-in synth pad layer that follows pitch. You can record loops and export them for sharing or further production, and you’ll find powerful features like random sequence generation, pattern switching, and a comprehensive array of tweakable parameters (cut-off, decay, glide, accent) to shape that classic acid growl. The workflow is designed for live performance and studio sketching, with Ableton Link and MIDI sync for tight timing, plus an optional suite of sounds and effects that push your sound beyond traditional 303-inspired basses.

As a complete loop toolkit, it exports to common destinations and supports routing through Audiobus 3 and IAA for multi-app setups. The Live Control panel lets you transpose and trigger sequences, switch patterns, and lock settings for seamless builds. Ideal for electro, house, techno, EDM, and other electronic styles, 2XB303 is your creative playground for acid-inspired patterns and dynamic overlays.
