Alongside our Renoise + Indamixx netbook-optimized production competition, I’m kicking off this week a series of CDM and guest tutorials on working with Linux audio tools, Renoise, and more. First up, here’s a basic look at how to route the free-as-in-beer linuxDSP effects toolkit into the powerful, modern, open-source DAW Ardour. Correction: I implied that linuxDSP had an open source license, which is not correct. It should be considered “freeware” but not free software. Ardour, of course, is fully open source, and this is as much a tutorial on how to use JACK to route effects as it is linuxDSP per se.

Here’s a switcher story of a different color: from the Mac, to Linux. It’s one thing to talk about operating systems and free software in theory, or to hear from died-in-the-wool advocates of their platform of choice. In this case, we turn to Kim Cascone, an experienced and gifted musician and composer with an impressive resume of releases and a rich sens of sound. This isn’t someone advocating any platform over another: it’s an on-the-ground, in-the-trenches, real-world example of how Kim made this set of tools work in his music, in the studio and on tour. A particular thanks, as he’s given me some new ideas for how to work with Audacity and Baudline. Kim puts his current setup in the context of decades of computer work. Even if you’re not ready to leave Mac (or Windows) just yet, Kim’s workflow here could help if you’re looking to make a Linux netbook or laptop more productive in your existing rig.

Stay tuned, as I’ll have some other stories on how to make your Linux music workflow effective creatively, particularly in regards to leaping over some of the setup hurdles Kim describes. -PK

Renoise has already earned a passionate following among lovers of trackers. The once-forgotten alternative to conventional sequencers, these music editors were beloved for their quick workflow and vertical, atomic approach to assembling beats and patterns. But Renoise is increasingly poised to appeal to other kinds of music makers, too, not just tracker purists.

2.1 you can sum up pretty easily: now you can integrate Renoise with other stuff easily. There’s ReWire support (appropriately enough for a tool beginning with “Re” in the title). And if you’re on Linux, you can pipe control and audio through the ultra-elegant, ultra-powerful JACK. (If you’re not on Linux, you may have just gotten a good reason to give it a try.)

This is on top of a rapidly-growing set of features like multi-core balancing, automatic delay compensation, audio recording (cough, Reason), and MIDI inputs and outputs. In other words, this is a tracker you can use without giving up modern luxuries. Maybe it’s like the difference between having a tent in gorgeous mountainous wilderness, and having a mansion with a hot tub and a T1 Internet line.

ReWire is the headline, but some of the live performance tools may make an even bigger difference. Live control tools and live pattern sequencing could make Renoise a lot more useful in performance, even without just ReWiring into Live and recording clips. The pattern triggering looks especially nice, because it brings a feature Game Boy trackers have often used live. (Add JACK on Linux, and you could add your own custom instruments.)

And, oh yeah, the whole program runs on every OS, has an incredibly responsive and involved community that impacts the direction of the tool, and is distributed on a shareware model rather than with painful copy protection.

Full disclosure: I’m slightly biased by enjoying a couple of beers with Renoise’s Dac, and by the fact that I think this looks completely delicious.

Here’s the full changelog.

Despite its quirks, Windows can be a wildly underrated OS for music. Of course, that has little to do with the way it works out of the box. It’s a matter of tweaking your setup so you reshape it into a finely-tuned musical tool. And I believe in sharing that info, because ultimately you should be able to make music on whichever OS you choose.

Rain Recording, a custom PC vendor that specializes in building systems for music and creative work, asked me to write up some of my favorite tools for just that job. For the first part, I looked at the unpleasant stuff — tools for troubleshooting your system and keeping it operating at maximum efficiency.

Part 2 is more fun — the goodies that actually help your musical workflow. I kept this entirely to utilities for MIDI and control, but thanks to the effort of some passionate musician-programmers, that winds up being an impressive toolkit. Quite a few items are Windows-only. (I do actually intend to cover Mac OS and Linux, too, but Windows stacked up pretty well.)

My picks, all free, donationware (and do donate and support these tools!), or relatively cheap:

Wormhole2 is a powerful, cross-platform (Windows + Mac) VST plug-in capable of transmitting audio between computers over networks. It allows effects chain routing between networked computers, boasts low-latency performance on LANs, and even works over WiFi or Firewire. But Wormhole2’s niche audience kept it from catching on more widely, and we hadn’t heard much from it lately, leaving some users worried Wormhole had fallen into a black hole.

plasq, the wonderful people who brought us Skitch and Comic Life, have been giving their audio tools new lives rather than orphaning them. We’ve already seen plasq’s live performance-savvy instrument and effects host Rax show up as an Audiofile Engineering product, and AE in turn recently promised in comments that great things were coming for Rax.

Now, we have some great news for Wormhole2: it’s gone open source:

End users can just download AU (Mac) and VST (Windows) binaries, plus a PDF manual. It’s even a Universal Binary for Intel Macs.

Developers: because VST isn’t an open-source format, you have to download Steinberg’s VST SDK to use it, but plasq will actually go the trouble of sending you the files once you agree to Steinberg’s license agreement. (AU isn’t either, but Apple ships all the developer tools you need with the OS.)

I’m really hopeful someone will build something cool with this. You’ll need something else to route MIDI (though the Mac does that over networks out of the box, cough, Windows). But there are powerful audio-over-network options here which would be hard to work out on your own. It’s unclear how useful Wormhole2 will be to the existing, open source JACK audio project, which is also capable of routing audio between apps and (via netjack) networked computers. JACK uses a client/server model as opposed to Wormhole’s plug-in approach. But for end users, having both tools available free is a very good thing, and the price tag is an extra incentive to be brave and see if these tools can help power up your rig.
