Marrying open source and commercial development, or trying to bridge analog consoles and computers – either task on its own might seem improbable. But yesterday, a newly-announced tool promised to bring together all those dimensions.

Ardour is the free and open source Digital Audio Workstation software for Linux and Mac. It’s widely underrated and has some terrific architecture underneath, with tools that are maturing at a healthy pace. Harrison is not an open-source developer – they’re a commercial manufacturer of analog and digital consoles and do proprietary DSP development. Conventional wisdom says the two shouldn’t be able to work together, but they did. The result is something called Mixbus. It’s got Harrison’s technology for mixing, atop Ardour (on Mac OS X, for now) for recording, editing, and arranging.

The Harrison half of the solution uses Harrison’s own DSP algorithms for sound, which they claim match the EQ, filtering, compression, tape saturation, and summing on their large-format mixers. But aside from sound, this is also about design: the layout only ever has one knob per function and metering is done in a conventional way. The result is not just a set of plug-ins, but a real virtual console inside your Mac. Interestingly, too, while you can use your Mac Audio Unit plug-ins with the solution, Harrison chose the open LADSPA format to implement their channel strip.

I imagined that the pricing would be something like a thousand dollars, given the pro target market, but the whole thing costs just US$79.99 as its introductory price. If it sounds anywhere near as good as the makers promise, it’s probably the best deal in mixing and channel processing anywhere. Here’s the product page:

Of course, the advantages of free software are more than price; it’s the ability to keep the source available, to be able to customize it, and to be able to run it on a variety of hardware and software platforms. So how does free software coexist here, with Ardour under a GPL license? Creator Paul Davis says that the free code for Ardour remains available in Ardour’s Subversion repository; only the Mixbus components remain closed. As for Linux support and not just Mac OS, which would in turn support more hardware, Paul says they’re looking into the feasibility of binary Linux distributions of Ardour and Mixbus.

For any commercial developers who think that you can’t work with open source projects – or, for that matter, if anyone thinks open source projects can’t benefit from collaboration with commercial developers – I think you’re wrong. And licenses aside, this looks like a nice solution for music making.

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.

The mda-vst collection of effects has been a long-time favorite for me. It’s a set of no-nonsense, unique, simple effects, just useful stuff that doesn’t have any unnecessary bells and whistles. Oh, yeah – and it’s free, making an easy way to fill out your effect arsenal. But until recently, the collection was proprietary freeware. Now, it’s GPL-licensed open source for Mac and Windows.

Included: multi-band distortion, drum replacement, amp and speaker simulators, de-essing, degrading, delay, detune, dither, dub delay, compressor/limiter/gate, envelope following stereo imaging and simulation, a Leslie simulator, multi-band compression, an overdrive, a really insane pitch changer, a 3D panner, a sub-bass synth, a couple of vocoders with different numbers of bands, test tone creator, flanger, pitch tracker, and more.

I imagine the access to code for these things could help people launch their own effects projects. And as Windows VSTs, it can run easily in Linux hosts that support that format, too.

Thanks to Marc Resibois for the tip. And you budding C coders out there, if you dig into the code, let us know.

You may have heard about Pure Data (Pd), the open-source cousin to Max/MSP and a powerful tool for visual programming or “patching” music and multimedia. Pd has even appeared in the iPhone app RjDj and creating generative music for EA’s hit game Spore. But actually learning how to use the thing? Or learning some of the more advanced possible techniques in sound synthesis and processing? That’s another matter.

Ever wished you could pack the sonic goodness and programming power of a soft synth into a hardware box? Dreamed of software that lived in a road case and had the stability and power-on capability of your outboard gear? You’re certainly not alone. That meant many of us were intrigued when soft synth emulator house Arturia showed off the Origin, a DSP-based hardware box that put their emulations in a box that wasn’t a PC.

Dave Dri knows touring with gear, as the founder of Seque and a live electronic festival vet. We got his impressions from across the Pacific in Australia. He’s upfront with everything he loves and everything that annoys. To bring a different perspective to Planet CDM here, I’m pleased to welcome Dave as a guest.

An Origin Of Sorts

Founded in France in 1999, Arturia has gained a solid reputation for the quality of its emulations of classic analogue synthesizers. If the soft synth emulations of the classic Moog Minimoog and Yamaha CS-80 have made Arturia a name in the industry, the news of its development of a hardware DSP system made for enjoyable speculation and furious Google searches for videos, news and reviews. While units in Australia are somewhat scarce at present, an Origin was supplied for review by Musiclab in Brisbane, Australia. Where the initial review was for music press print media, there is so much more to this module that we can take a deeper look and share with the CDM community some of the issues and notable features of the Arturia Origin.
