JC-303

JC303 is Bass Synthesizer Audio Plugin, clone of Roland TB-303, a community-driven project open to contributions in coding, testing, bug reporting/fixing, design, and improvement ideas. JC-303 also makes use of other open-source projects, such as Open303 and GuitarML for DSP engine.

Key Features:

• Pure 303 Sound: The 303 sound engine is based on the Open303 project, which has benefited from over 15 years of community-driven development, research, and reverse engineering to achieve the most accurate sound possible, closely resembling the real TB-303.

• A.I Overdrive: Based on GuitarML's research and development in artificial intelligence and machine learning-based models, JC-303 replicates pedals and amps like no other DSP solution available, with over 180 overdrive pedal and cabinet models.

• Devilfish Inspired Mods: Created by Robin Whittle in 1993 and considered one of the most sought-after third-party modifications of the original TB-303, you can try out some of the same synthesizer sound modification parameters on the JC-303.

• Opensource to the bones: From DSP to GUI, all the source code and resources needed for you to compile on your own, learn, or modify are available for life and free of charge. Want to contribute to the project? Just fork the repository and submit a pull request.

• Cross-Platform Compatibility: Available for Windows, MacOS, and Linux.

• Plugin Versatility: VST2, VST3, LV2, CLAP and AU compatibility for seamless integration with your favorite DAWs.

About Open303

Over the span of a decade, a KVRAudio community of TB-303 enthusiasts, led by Robin Schmidt, started the Open303 project with the intent to create an open-source digital emulation of the TB-303. They dove deep into their oscilloscopes, engaged in circuit reverse engineering analyses, and debated the inner workings of our beloved TB-303, striving to achieve the closest possible sound replica.

It all began in 2009 when Robin Schmidt called for collaborators for the TB-303 emulation project on the KVRAudio forum. Read the Forum Post here.

About GuitarML

By capturing the sound output of real overdrive pedals and cabinets, the GuitarML project uses machine learning to train models that can be used in real-time to recreate the sound of actual overdrives! It is a community-driven project with a large and growing library of trained pedal and cabinet models available for download and testing, offering unlimited tonal possibilities.

An Evolving Project

On the roadmap, one of the main features is to add a cloned step sequencer of the real TB-303, giving you the authentic rave signature to create evolving acid lines.
