midilab has recently released a Juce port of Robin Schmidt’s renowned Open303 DSP engine, making the Roland TB-303 clone accessible across different platforms and plugin formats. JC-303 also aims to deliver a faithful clone emulation of the TB-303 step sequencer.

Open303 embodies the essence of open source development. It all began when Robin Schmidt called upon a community of passionate individuals to embark on the quest for the ultimate TB-303 clone on the KVRAudio forum.

Over the span of a decade, enthusiasts dived deep into their oscilloscopes, engaged in circuit reverse engineering analyses, and passionately debated the inner workings of our beloved TB-303. The result? The finest emulation of the TB-303 ever created, and it’s open source! Achieving high-quality Virtual Analog (VA) filters in the DSP realm is notoriously challenging, but Open303 conquers this frontier with excellence.

JC-303 is available in VST3, AU and LV2 plugin formats.
