The Roland TB-303 is an iconic analog Synthesizer best known by every musician. Manufactured by Roland from 1981 to 1984 and re-released last year under the Boutique range, this instrument played a major role in the development of modern electronic music, mainly for the acid genre.

With the AcidBox, Audio Blast, a software developer tries to bring back this iconic synth to every DAW. It’s a bassline synth instrument featuring a 303-like sequencer with custom function and a complete effect section.

The AcidBox is a Bass Line Synthesizer recreation of the iconic TB-303 synth with a new interface and focused on real-time creation of sequences and tweaking in live situations.
