Linux isn’t the easiest platform to use when it comes to music production. But it is one of the most flexible, and there’s no argument against it being the cheapest. This is particularly important if you have a musical bent, because few musicians are lucky enough to be able to freely spend money on their passion, making Linux the perfect choice. And regardless of price, if you don’t mind a little GUI graft and a slightly steeper learning curve, audio software on Linux can compete with the best commercial developments. PureData can replace Max/MSP, for example. Audacity can replace Wavelab. Either Muse or Rosegarden can take a fair crack at Logic or Cubase’s crown.Tux, eh? He gets everywhere. In this case he\’s made his way inside our collection of valuable music equipment. Pesky penguin. But the most mature and capable application in the Linux canon is Ardour. It’s the free software equivalent to the industry standard ProTools. It doesn’t have MIDI, nor ProTools’ hardware lock-in, but it’s just as flexible and stable when it comes to audio recording, editing, mixing and mastering. Which means, if you’re into making music, there’s no better option on a budget.
Finally an article that does a reasonable job explaining how Jack, Ardour, Hydrogen and more work together to create a pretty cool digital audio workstation.
