With an unmistakable sonic signature brimming with warmth, energy and character, the Roland TB-303 Bass Line defined the acid house movement of the late 1980s. Widely misunderstood when launched in 1981, the true revolution began several years later when electronic music producers rediscovered the quirky box, unleashing the hypnotic, liquid sound that captivated a generation. The TB-303 Software Bass Line delivers this historic instrument in a DAW plug-in, with circuit-level sonic accuracy and useful modern enhancements.

Humble Beginnings
Some instruments are so groundbreaking they create entire musical genres. The TB-303 is one of these influential instruments, but it wasn’t always seen that way.  When Roland released the TB-303 in 1981, it was marketed as a computerized bass machine to simulate a traditional bass guitar, but didn’t quite catch on. Later on, inventive electronic musicians discovered the 303, often on the secondhand market, and found new uses for its recognizably fluid low end.

Iconic Status
Using the 303 in new ways, these pioneers of early house music inadvertently created a sound that came to be known as acid. This new sound ignited other electronic  music  genres and, like the Roland TR-8’s influence on hip-hop, the TB-303 played an essential role in late '80s to early ‘90s rave culture. While we may never really understand why the 303 sound makes people want to dance, there’s no denying its power, influence and unwavering ability to get a party started.

Plug In Your Own TB-303
The TB-303 Software Bass Line takes the classic instrument to the next level. Utilizing Analog Circuit Behavior modeling, the virtual TB-303 captures the hypnotic tone of the original hardware and forms the perfect complement to the TR-909 and other classic Roland instruments. The iconic interface and signature crunch and squelch of the original are perfectly reproduced, while adding new features which surely would have turned heads back in the day: 

Edit Window 
The 303’s new editing window is one of the most striking features. For the first time, you can create and edit patterns with a visual interface. With the ability to see the DNA of a preset pattern, you can edit a variation, or start from scratch and then step-edit a new pattern, using up to six octaves with user-defined scales, accents, slides, pitch manipulation and more. The new randomize/generate functions create an endless supply of classic 303 patterns.

Five Play Modes
With five new play modes (Forward/Reverse/FWD&REV/Invert/Random) the TB-303 Software Synthesizer widens the ability to experiment. These new functions allow sonic alchemists  to twist and turn the bass, changing direction at will. 

More Memory and Manipulation 
For the first time, the TB-303 can hold up to 64 patterns and 64 patches per bank. The eight variations of a pattern are still accessible on the UI faceplate. Plus, with 32 preset patterns and 48 unique sounds, the 303 arrives complete with sonic templates for you to explore. 

The  Secret  Panel 
A hidden panel on the far-right corner of the 303 unlocks a variety of new tone-coloring features. Explore  the expanded  circuit modification via the new VCF trim, Vintage Condition and Master Tune knobs. The onboard effects, including distortion and delay with tempo-sync, are sure to inspire fresh  ideas.
