Armed with the passion to bring to life a virtual 303, we have gone to great lengths to recreate the ultimate acid machine. We used our very own vintage 303 as reference, running the machine through a battery of feature specific tests to better understand and emulate in our application.

What we discovered is that the 303 is not just another subtractive monosynth as some may claim and we believe that our emulation captures its true expressive essence. Our emulation has nuances that only owners of a real 303 know such as what happens when all of the pattern steps are slides or how each parameter truly reacts to the tempo.

Not only does Digital Bass Line give you a full featured virtual analog synthesizer, it also gives you two versatile effects stomp boxes to bring more life to your bass lines. The easy and intuitive design makes creating bass lines fun and quick, whether you are a veteran of analog and digital synthesizers, or a newcomer to electronic music.
