It is a JUCE port of Robin Schmidt’s Open303 DSP engine, aiming to make the powerful Open 303 accessible to a broader audience. Our primary objective is to offer a seamless experience, allowing musicians and producers to harness the incredible power of the Open303 DSP engine. Beyond just replicating the distinctive sound of the original TB-303..

We recognize that the TB-303’s unique character is not solely about its sound but is also defined by the entire gear, especially its legendary sequencer. About Open303, the project embodies the spirit of open-source development. Originating from Robin Schmidt’s call to the KVRAudio forum community, it evolved over a decade with enthusiasts delving into oscilloscopes, engaging in circuit reverse engineering analyses, and passionately debating the inner workings of the TB-303. The result is the finest TB-303 emulation ever created, available as open source. Open303 excels in achieving high-quality Virtual Analog (VA) filters in the challenging realm of DSP.
