Sick of paying top dollar for your mixers? Yeah, so are we. But we’re not so sure about building our own from scratch, even if you can get the full source code and build schematics to whip up your own Auroroa open source mixer. (They’ll sell you posers one pre-built, too, if you want to front it.) Matching, scratching, and tasteful song selection? You’re on your own there, pally boy.
