Introducing L2Ork, World's First Linux Laptop Orchestra 86

Agram writes "Take a netbook, Wiimotes, Nunchuks, and hemispherical speakers (which were once IKEA salad bowls), toss it up with some Ubuntu goodness and what you get is Virginia Tech's L2Ork, the world's first Linux-based laptop orchestra. With its affordable design and support from the Linux community, L2Ork hopes to bring laptop orchestras to K-12 education and beyond. So, regardless whether you wish to hear how L2Ork might sound or to learn how to build your own Linux-based *Ork infrastructure, perhaps this is a good opportunity to reopen the age-old debate: is Linux finally ready for some serious audio work?"

    Unfortunately companies that make good DACs, like MOTU, don't provide Linux drivers. It's no good to try and work on a Linux box if you're limited to the built in stereo 1/8" soundcard.

    So while it can work for small hemi-speakers, trying to drive a full surround setup is near impossible without good proper DACs.

    • i don't know about that.

      if you look through the alsa's driver list, you will find many professional-grade multi-channel interfaces.

      the alsa project has brought support for some excellent professional interfaces - with a few exceptions, like motu (to me, motu have always been the tops for midi, but definitely not the best dacs out there)

        The Layla 3G is a decent home studio interface, but as you say, there just isn't any software that runs natively in Linux that is remotely appropriate for professional work.

        I've tried to run Cockos' Reaper under Wine, but I find jack just too much of a hassle.

        However, Reaper has features that allow you to use a Linux machine to offload effects processing chores to via Ethernet and it works great. It makes my workflow much more efficient and allows me to do much more in real-time. And of course, a Linux box with a RAID array is an excellent sample server and rendering platform. Reaper is quickly becoming my favorite DAW software because of it's ability to leverage Linux machines in a professional studio environment. Someday, I hope to see a Linux port of Reaper.

        Linux may not yet be ready to act as a standalone music production system, but it definitely has a place in a professional music production facility. And of course, it's a great platform for experiments like the one described in this article.

      A general rule of thumb is that latency and throughput are opposing interests. For the majority of users and uses occasional latency is a good tradeoff for higher overall throughput and performance. For realtime applications low latency is a good tradeoff for lower overall performance. Linux can be tuned in many ways for many different use cases and may not suit your needs right out of the box.

    ...but no simpler.

    It's an interesting idea and may have beneficial applications for entertainment, music therapy or childhood education, but I don't see much potential for any real [read artistic] musical applications. Excepting, possibly, interactive performance art or something.

    The richness of a real symphony orchestra's sound is tied to the complexity and expertise of about a hundred different musicians at levels of superb mastery working together as individuals to recreate and interpret a composer's vision. I don't see how it would be possible to do anything different from the already tired new-agey synthesizer muzak with a tool like this. Of course I feel similarly about replacing the big band with an electric guitar.

    • In a cool or scary development, depending on how you want to look at it, computers can do an amazing job of replicating symphonies and other musical groups. Powerful CPUs, lots of RAM and big harddrives mean it is feasible to extensively sample instruments and then have a computer make music using it. Go have a look around EastWest's site and you can see all the various kinds of instruments and groups they've got sample sets for. For orchestra's it is their Symphonic Orchestra product (http://www.soundsonli

        It's IO bound. A flute player can alter the tone quality produced by changing their oral orifice from oval to circular, in addition to breath speed, vibrato, airflow angle against the flute, and then the notes being played.

        That seems, to me, to be the whole "problem", and it's one that we're creating. By comparing the present with the past we're creating needless conflict.

        Computers can create some really complex, incredibly beautiful music. Machines can do things that no human orchestra is ever likely to be able to recreate.

        Human instruments (please leave off the skin flute jokes :) ) can also be beautiful, but have different sets of inputs.

    While I'm not into Laptop Orchestra's, I do use Ubuntu Studio now for MOST of my audio processing.

    Only 4 years ago, I couldn't make it work. I use a Presonus Firepod to record my band, and also have some other gadgets. The only thing I am really missing is something like Gearbox for my Line 6 PodXT, there just isn't a substitute yet for Linux. No worries though, I pretty much have my board setup the way I want, so rarely even use Gearbox anymore.

    Anyway, back to my point. I now use Linux as my DAW, as a sequencer, and increasing for my general computing needs. I love Jackd with Ardour and Patchage. It's gotten to the point where it's not just a suitable replacement for Cubase or Pro-Tools, but is my preferred setup. Now that my ATI drivers are finally working properly with the RT kernel in Ubuntu 9.10, I am finding the cube desktop actually useful instead of just eye candy. I can have my mixers, editors, patchage, etc. on separate workspaces and get to them easily.

    Just a month ago, I had a friend of mine come over to check out my setup. He is a drummer that also wanted to start home recordings. He bought a ART Tubefire 8, and was very disappointed with the crippled Cubase LE that came with the hardware. After seeing my setup, he went out, bought a $300 computer and a firewire card and asked me to get him setup. Knowing nothing about Linux, or Ubuntu, etc, he is now using the setup to great success.. If there was ever a killer app for Linux, this is it, at least for music professionals and hobbyists.

    The major drawback is hardware support still has a ways to go. But, right now there is the ability to get high end music recording equipment working very well right out of the box. I am a very satisfied "customer". And to think, 4 years ago I never thought it would get there.

    So far Linux does have musical capabilities but not enough and not easy enough either.
                For example converting a treble clef trumpet part to a bass clef trombone part should be a no brainer and printing it out should be a breeze as well. Further converting a melody played through the system into a score should also be simple.
                Having to use different programs to print a score, convert a score and play a score will not attract many musicians.
