Jeskola Buzz isn’t the most popular audio software out there but it’s mean powerful and has one devout group of developers and users who keep adding powers to it. It’s a music tracker built with a modular interface that lets you build compositions in a visual and very powerful way.
One of the great beauties of Buzz is that it’s free. But not only is it free, all the modules/plugins for it are free as well. And there is a bewildering array of them, accessible from the Buzzmachines.com database.
Among the many free gems available for Buzz is a couple of synthesizers that very well emulate the sound of the infamous Roland TB-303; the HD Real 303 and Oomek Aggressor 303. Here’s a video demonstration of the HD Real 303 being used to compose some wicked, squealing 303 sounds.
Oomek Agressor 303 is easily as awesome as HD Real 303, it’s just subtly different. Fortunately, Buzz doesn’t leave one torn as to which to choose, they’re both free and available for use in any Buzz composition.
