DeMuDi Linux 92

Sleen writes: "DeMuDi stands for Debian Music Distribution. This is the first distribution of GNU/Linux whose sole purpose is to create a stable OS for Multimedia. The project is led by Guenter Gieger who is the developer of the Linux low latency driver for the RME Hammerfall 96xx series. Combined with realtime kernel patches, the Hammerfall card in Linux can achieve hardware level latencies. Though many are already using Linux to make music, Guenter has started this project to consolidate the decentralized resources needed for setting up a linux system for multimedia. Drivers, applications, a realtime kernel and many other things are missing from the typical linux distro. If anyone wonders what is available to work with, take a look at the packages page. They include multitrack hard disk recording software, physical modelling and virtual analog synthesizers, beatboxes, midi sequencers, processors, and Advanced Open Architecture Synthesis systems such as Csound.

    For the record, there are as far as i can tell NO music synthesis programs for mac os x at this point. Cubase is the only nonlinear digital mixing system that i have seen that seems to even have a plan on Mac OS X migration, and they have NO timetable-- they are simply "looking into the possibility" in case demand should arise at some point. Neither Cubase nor Protools will even work in *classic* (as if classic wasn't enough of a hassle anyway), and i suspect Reason and MAX/MSP fare little better (though i have not tried them). A few shareware sound editing apps have been carbonized-- for example, Amadeus, which is shaping into a very nice sound editing program (it can even do VST plugins now) even if it can't do tracking-- except that they are still hamstrung in a number of ways. For example, i have yet to see ONE application capable of recording audio which has been able to implement an audio playthrough option into their record feature under mac os x-- including carbonized apps such as amadeus which have playthrough in their classic versions! I have begun doing some work with protools free recently, and must boot into OS 9 every time i wish to record *anything*, much less mix.

    I am not aware of any MIDI hardware or software that has drivers available for mac os x at this point-- but then, because i can't find any software to use the hardware with, i haven't been looking very hard. (If you can point me toward any MIDI hardware where the company DOES have a commitment toward os x compatibility, PLEASE let me know, as i am in the market for a cheap os x compatible midi keyboard!!).

    As of now, OS X's audio capabilities are completely undeveloped. This may have something to do with the fact that the APIs seem to have only recently stabilised, and there has been little time for porting to take place; i don't know. Either way the process of moving the Macintosh as a platform for digital audio recording and editing into the world of OS X has not, from where i am standing, even *begun*, much less reached a point where it even begs COMPARISON to something like DeMuDi, which by contrast to os x seems to be an INCREDIBLY mature platform for professional musicians.

    Pity, because i started looking through the CoreAudio/CoreMIDI API documentation yesterday, and it seems like a *really* nice programmer's interface. Well, we'll wait and see..

  • THis isn't the first "musicians can't edit conf files" post I've seen in this thread, and I'm curious as to where this attitude comes from. You say:

    "Musicians are very, very rarely computer jockeys, and being weaned on the MacOS and Win32, most of them will shit a brick when if they have to deal with the CLI or edit a .conf file."

    On what do you base this? It would seem that there is a lot of evidence to the contrary: musicians were the first artists to really embrace computers, there is a long history of musician-hackish tendency crossover, modern electronic music gear requires loads of tinkering that people who do music on computers are often drawn to. Have you ever used a modern keyboard? It's ridiculous. Open a KB magazine and the articles are all "OS patch this, Driver revision that". Very computer-techy.

    Have you ever used an old keyboard? OO design before CS had it, exactly. Modular/old-analog synths (esp. machines like the Korg MS-20) had the whole OO pattern down with data/functionality hiding, modularization, message passing, many musicians are quite fluent in these concepts.

    I'm not trying to argue with you or "set right a common misconception" or anything, I just see this a completely different way from the way you and many /.'ers seem to. Why do you think musicians aren't technical. I'd argue that of all artists, they tend to be the *most* technical, and if you had to draw any subgroup of society but CSers, programmers, and engineers, I'd think the group best able to deal with a computer would probably be musicians. Yes, even over other scientists like physicists and biologists.

    Have you ever seen Max or MSP? I've seen some shitty code by engineers and physicists, but the code some of those musicians are basically writing in Max is pretty good.

  • overspecialization (Score:2)

    by Anonymous Coward
    These types of developments excite me because of the good things they say about the flexibility of linux, but I think that there may be a drawback to this level of specialization for linux as a whole, and an alternative that can avoid this drawback.

    Maintaining a distribution requires a lot of overhead beyond its primary focus. Things like updating system packages, maintaining compatability lists of entire systems of packages, documentation, and etc. fall into this category. This overhead is present in all distribution development alike, and uses up precious developer time. What this means is that if there are distros for every single specific task from pr0n viewing to juice-carton designing, then this overhead will take its toll on the the linux development community for every single one of those distros. The work that must be done to take care of the overhead is work that has already been done by every other distro.

    To put it mathematically, suppose the overhead in maintaining a distro needs the work of 10 dedicated people, and suppose there is a total of 100 developers for linux. If you have one very flexible distro, you will have 10 people working on the overhead, and 90 people working on the good stuff such as web browsers, editors, GUI toolkits, etc. But if there are 5 distros total, you will need 50 developers to work on the overhead altogether. They will all be duplicating the work done by the other overhead-workers. This would only leave 50 people to work on the good stuff. We need good stuff more than duplicated effort.

    The only solution I see to this is simply for people who want to roll their own specific linux distro to try instead to modify existing distros, building ontop of the existing infrastructure. Does apt-get install task-audio-studio or task-ipmasq-firewall or task-thinclient sound good to anyone else? :D

  • The point of this distro is not to solve the age-old mysical problem of linux: no apps.

    The point of this distro is to put linux in a *much better* position to become an architecture for development of *hardware-based* music systems using open source tools.

    This distro should be at the *end* of the MIDI chain, not trying to drive the front of it.

    (In my opinion, software sequencing is held in too high regard by musicians. try playing synth music *live* as much as possible, and see where that takes you for a while... but I digress...)

    I'm excited by this distro because it means that with the right tools, and good MIDI *input* capabilities, I could write a pretty fucking amazing hardware sampler system...

    Better than Emu. Better than Akai. And yes, even better than the Yamaha samplers.

    Music production requires a decent amount of hardware to work right, particularly for those that like to play a instrument directly to a digital version (ala midi keyboards). Notoriously a heavy OS can get in the way as to increase latency and reduce the quality of the final product. Linux is well suited since the OS can be very small and avoid latency. I'd love to see a similar project used for video technologies too; sure Linux doesn't have a Premiere-like program, but if someone develops the groundwork for a sleek kernel to avoid interrupting digital real-time editing, someone will write the necessary tools.

  • Get a soundcard that does hardware mixing. The Trident 4DWave NX series of cards do this quite nice and cheap. You get 32 audio devices to play with (i.e. you can open up to 32 audio apps simultaneously). Of course you can run esound as one of the 32 to increase this in software. The Live! cards supposedly do this too. All this with ALSA [alsa-project.org] drivers of course.

  • Too bad linux is still stuck with single threaded X.

    That's not the problem, your videocard is not threaded so a multithreaded X server will not buy you any significant speed increase.

    A good multi-threading windowing toolkit is whats needed. Qt 3.0 is supposed to fill this gap, However I've had very good results with GTK+ too. I ported some code over from BeOS and it runs beautifully under Linux/X. Unfortunately GTK+ uses one big fat global app lock for GUI threading but with careful design you can get impressive results .

    And I don't think musicians will be happy with the idea that they need to install a patch in order to get low latencies. It should be default so that developers can just assume everyone will have it.

    That is coming in the 2.5.x kernel series. But don't let that stop you to start experimenting :)

  • Would it be a reasonable task to cull the pachage list to act as a stereo component-style MP3 player? (attractive component-looking case not included)
  • I think musicians more than most computer users would be willing to use whatever it takes to get the job done, putting aside the stuff they've used before to try something new.

    VST support would probably be the easiest to achieve, as VST plugins are already cross platform (Mac and Win) although I don't know the details of how painful it is to port one. DXi would be a little more difficult but having seen Windows avi codecs interfaced to in Linux, ActiveX controls and the WINE project, I wouldn't be surprised to see wrappers for the Windows DXi plugins and VST instruments.

    Oops, reading Ardour's features page [sourceforge.net] bears my point about VST but introduces some IP stupidity on the part of Steinberg.

  • almost all of the QNX is just ported from linux so why not just use the real thing instead?
  • But, to quote the ad, I'm "sick of crashing." Especially while I'm recording something. ;-)
  • The main thing here is the low latency patch. Linus refuses to admit it to the kernel because it's kind of a kludge (but not really all *that* bad). Many musicians might not know how to patch a kernel or even install a binary kernel safely. If you *can* do it yourself, it's probably a better solution.
  • Check out the MusicKit (from the good 'ole days of NeXT) here [musickit.org]. It's a OO framework that combines the flexibility of Music 'N' systems (like CSound) with realtime control of MIDI. Plus, a Linux/GNUstep port is being worked on.
  • I know that this is not going to be answered, but will be marked a +1 or -1 on /., but when I think of needing a Realtime or Hard Realtime system I have always used QNX. Why would someone want to use Linux, and patch everything in sight and work so hard to make Linux a pseudo-"real-time" system for use with your system?

    I think it's for several reasons.

    First, QNX has a reputation as being for embedded systems. Consequently, most of the developers in Free Software music circles think of it as being for those "weird" marketing types who want to make internet washing machines available--not for serious musicians. Also, most of us aren't interested even in "embedded" music applications. We're more interested in a regular general purpose computer that hosts a lot of useful but separate applications. It's just kind of a mindset that prevails.

    Second, there's probably even less sound card support for QNX than there is for Linux. Especially in the high end (which is all that really matters in this case). Plus, we've already almost got ALSA ready. ;-) And quite a few apps already in common use and more on the way.

    Third, the latencies with Linux are so good now (with Andrew Morton's patch) that hard real time doesn't even seem worth the trouble for something like this.

    Finally, QNX just doesn't have the mindshare that Linux has and this probably counts for more than anything else. I think NeXTSTEP should be ruling the desktop right now and we should all be using BetaMax instead of VHS. Kinda sucks, but that seems to be the way things usually work out.

  • At school, we're using Deck and Peak on a Power PC. (We've had a lot of problems with it. Although, not as many as with our DAT deck that nobody will CLEAN!) Elsewhere, I've used everything from Win 3.1 to Win 95. Haven't tried 2k yet, though. At any rate, Ardour + RME Hammerfall works quite nicely. ;-)

  • Not to point out the glaringly obvious but I hardly think something named (expanded) *DEBIAN* Music Distrobution is a "start-from-scratch" proposition. And completely replacing your kernel, and (probably) other major software with real-time versions, as well as a different orientation (probably easier setup, we all know musicians aren't techies ;-), etc, does constitute a good reason for forking the distro, at least for a while. Maybe once they get it all shaken out and the bugs worked out they will merge back, but at least for now it is a wise idea.

    Sheesh.....
  • (Note that since the site is EXTREMELY slow I can't browse the list of packages, so maybe I'm missing something).

    This reminds me a lot of BeOS. Be is very, very well suited for music and other media production. But the hardware and major software support never materialized, so it didn't catch on. Unless companies like Cakewalk, Steinberg, and Logic start porting their apps to this new distro, it really won't matter how kickass the OS is. Maybe if VST or DXi support was available in the OS, things might be a little more attractive to potential developers.

    I suppose that you *could* see some pickup in use if tools in the same league as those released by the companies above is developed for this distro. On the other hand, the Gimp is available for Linux, and I still don't run into many serious graphic designers who use it instead of Photoshop. Most folks are gonna stick with what they know unless there is a compelling reason for them to switch.

    I'm also a little worried about the issues of useability that normally pop up with Linux distros. Musicians are very, very rarely computer jockeys, and being weaned on the MacOS and Win32, most of them will shit a brick when if they have to deal with the CLI or edit a .conf file.

RTlinux is overkill for this type of problem, and requires specialised hardware support in the form of new drivers for the soundcards.

  • This will definitely give us a good solid dedicated multimedia box, but what I for one really want is my current distro - which is is running a fairly lean, fast kernel - with all these applications added. I'm quite happy to shut down any resource hogging processes while I record/mix/edit etc, but I can't really be bothered setting up a whole new box just for this, or wiping my one as it's quite happy right now.

    I'm sure other users are the same - it'll only be the dedicated music makers who will go to these lengths. Of course, maybe us part timers have no need of such low latency, I mean I use Cubase on my Windows partition pretty successfully, but aside from that and Unreal Tournament I would rather dump that partition completely.

  • but the MIDI spec is pretty daunting looking to me....

    The MIDI spec isn't daunting at all... when I was younger and more innocent I wrote a couple of MIDI file processors that stripped various bits out, have to see if I can find them... the most difficult bit if I remember was delta-time - the length of time in between events. Let me explain:
    In MIDI, you have pretty much two major types of data: Status bytes, and data bytes. Status bytes always have an MSB of 1, and data bytes have an MSB of 0. Status bytes begin with an ID nybble, the second nybble specifies the channel (yes, there are 16 channels, and 16 types of status event).
    Having specified the channel, the data goes on to do whatever it has to do - for a note on event, you must specify the key (in the range 1 - 127, well encompassing an 88 note keyboard), and the velocity, again within a 0 - 127 range.

    Things get complicated when you include system exclusive messages - they are proprietary to each manufacturer and model - and continuous controllers. There are 127 possible controllers, some of which are reserved, e.g. volume is 7, expression is 11, modulation is 1, pan is 10, etc. Reverb and Chorus are included in there somewhere, as are certain other parameters depending on the midi module.

    MIDI files can also contain messages such as lyrics, copyright, etc. Good clean fun.
    For more information, there are many resources available online.

I already use and develop such a system for multichannel audio work, and the kernel is simply not an issue. I run with h/w interrupts every 1.3ms, and nothing ever goes wrong. --p
  • RTLinux provides realtime *guarantees*. The low latency patches merely make it overwhelmingly likely that you will make your timing deadlines (if you use POSIX RT scheduling, anyway). No, 0ms is never possible, but RTLinux can offer timing guarantees on the same order as the h/w (tens of microseconds).

    As the author of Quasimodo, I beg to differ. Quasimodo is not a sequencer, and more importantly, its a dead project at this point, for many reasons. You should be looking at MusE [muse.seh.de] which is a really high quality MIDI sequencer. As an aside, if the MIDI specs look daunting, I would forget about even considering programming in this field. MIDI is one of the simplest protocols there is, and one of the simpler problems in the area of MIDI/Audio programming. --p

  • I wouldn't be able to switch my desktop music studio to linux entirely until there is a decent music notation editor. Seems that any score I'd create in current linux software would be given a big fat 'F' if I turned it into a college composition professor, just based off of notation style. The standards are very high. It seems that lilypond is the most advanced, but their longer examples and their font doesn't hold a candle to Sibelius, Finale, Igor.

  • As I am a Debain user and work mostly with video (1394, DV, Kino, gstreamer), I became interested in this distro. However, after inspecting the packages list it becomes apparant this is an *audio* distro, not a multimedia distro. What about video, drawing, animation, and 3D tools too? Oh well, +-DRD-+

  • if you read their site, they haven't built a distribution from scratch. DeMuDi stands for Debian Music Disttribution, meaning that they're working to add more multimedia drivers, applications, and capabilities to an existing distro (which, i might add, is the distro you're using).

    In an earlier /. story, an animator from ILM explained that the reason they dumped Windows for Linux was not the cost, but that they could customize Linux to meet their needs.
  • This is exceptional. Not that it will take off immediately (because Mac and Win are already so established in this field) but it does come at a good time. Software distributors will raise an interested eyebrow when they see that Linux distributions can be tailored easily to revolve around a specific task structure; it will provide them an incentive not really present on mainstream OSs, because the first movers will have the power of a whole Linux distro more or less revolving around their software. Good idea!
  • that this had been around about three years ago... I might still be in school full time, and I might still be a music composition major! lol
    Well, maybe not. ;)
    It does sound like a great idea. This is exactly where money could be made! Make the specialized distros instead of even worrying about the blooming desktop! People will use whatever is there. However, when something can be used as a _real_ tool, the interest starts to rise and with that, usage follows.

  • What do almost all cutting-edge games have in common? Loads of multimedia.

    Maybe this would be a good place to lead game development from, as they are working on sound and video, things that aren't usually considered Linux's strong point. Besides, if hardware vendors can be pointed to a specific distribution to support, they might be more likely to create useful drivers than if they are asked to "make a linux driver".

  • I have actually been very interested in these low-latency patches of which you speak. I've heard of patches by Ingo Molnar and one by Andrew Morton. Which one do you have?

    Also, how much faster is the performance? It would seem that if this improves desktop performance it should be included in distro's like Mandrake. Also, how responsive is video playback with these patches installed? I'm interested in playing divx, avi, mpeg, etc and it appears that windows is still better at this sort of thing. I'd rather use Linux for all my desktop usage!

    Finally, which low-latency patch did you use as I have heard of a few. If you could post the link I'd greatly appreciate it.

    Cheers
  • I don't know the details, but shouldn't it be possible to add the DeMuDi source lines to your sources file in Debian? In principle, since this is a Debian based distribution, all one would need to do is a simple apt-get. The great thing about making this a separate distribution is that if all you want is music at first, you start with DeMuDi. Want to upgrade to the whole Debian distribution? Change your sources.list to point to a Debian mirror. I don't know if this is how the DeMuDi maintainers are thinking, but it should be.

    I think this is cool stuff, and means that the main Debian distributors don't need to put as much effort into maintaining these specialized packages. It is in keeping with the specialized Debian Jr. distribution that is currently in progress, as well.

    Keep up the good work, and I for one am completely in favor of it.

    I have to admit, even though a specialized distro is not really a new concept I'm quite intrigued. Imagine that instead of selling a card that plugs into a PC (as it's sometimes done now), a company could sell an entire PC with a home brewed Linux distro. Obviously the price would be higher but that kind of custimization could lead to some really interesting setup from a professional perspective. Kinda like the embedded concept but scaled a lot higher!

  • As a huge fan of electronic music and occasional dabbler in writing it with my Mac and MIDI gear, I hearby announce that if Linux and Free software can replace a Mac running Cubase with VST plugins, Reaktor [native-instruments.net], Reason [propellerheads.se], the new Absynth [native-instruments.net], and other staples of electronic music, with MIDI and low latency, I will SHIT MYSELF LIKE AN INFANT IN DIAPERS!!

    i.e., I would really be impressed and would install it straight away. :-)

  • You can happily roll your own, or let them roll it for you. The applications are probably mostly in unstable already, the main thing is the low latency patches and possible driver additions to their kernel.
  • +1 Funny.

  • If I remember correctly, AFAIK.

  • Those low-latency kernel patches aren't just for audio guys - they're great for a desktop system as well. I find X and KDE to be more responsive with them installed (esp. when using drag-and-drop) and KDE's audio daemon aRts works much better with them.

    I guess the reason they're not included in Linux releases is that they aren't suited for a server, which doesn't need low latencies. However, if you're running a desktop system, you should definitely look into these patches. I think Mandrake should include them by default.

  • I think the ones by Ingo are for 2.2.x and the ones by Andrew are for 2.4.x. Or maybe its the other way around. Anyway, I think that the kernel version you choose dictates which set of patches you need.

    how much faster is the performance?

    Its not exactly faster, just more smooth. Consequently it won't make your boot time shorter or improve startup times of applications, or improve game framerates (I think, although I could be wrong). It will make your mouse pointer move more smoothly while your system is under load (though enabling DMA on your hard drive gives a bigger improvement), it will allow you to set a lower latency on your sound programs, giving you faster response, and it will in all likelihood help videos (I'm on a modem connection and have very few videos to try it with).

    As for links, Google is your friend. A search for Low-Latency Kernel Patches [google.com] reveals many interesting links, the most interesting being a site with history about low latency in Linux [linuxdj.com] and a link to Andrew Morton's scheduling page [uow.edu.au] where you can download patches for many 2.4.x kernels.

    If you haven't done it already, enabling DMA on your hard drive will probably make a bigger difference than these patches, though, and without a kernel recompile too! Definitely look into that.

  • DeMuDi?

    Ugh. It sounds like a Turkish word for diarrhea.

  • I alse see Csound is on of the packages. Csound is pretty amazing stuff that can create unique synthetical music. And now that CPU's are getting a lot faster, it can probably be used to play music in realtime.

    As opposed to Midi, a csound instrument can have an unlimited number of parameters. This distro could become the most powerful music creation platform ever.

  • Why not just work with a current distro (debian) instead of doing a whole new distro from scratch? I run debian, I would want multimedia capabilities --- so I should give up debian for this distro?
  • hmm... BeOs is a single user, extremely GUI-oriented OS that was supposed to be so friendly that it would be the perfect choice for novice users. Oh yeah, and the multimedia stuff is integrated with the OS, iirc.

    That sounds a lot like linux, right?

  • Since BeOS is practically dead, I think this is a lot better, heh.
    Sad to see Be fight for its life instead of developing more cool techonology.
    I hope they open source it before they go under...

  • of course, what we really need now is a linux distro specifically for downloading porn off the net; something that'll search google and the newsgroups and sit on IRC and just d/l the porn for you.

    it'll need some multimedia, and it's own plastic cover.

  • >BeOs is a single user, extremely GUI-oriented OS that was supposed to be so friendly that it would be the perfect choice for novice users.

    except for that whole "no software for it whatsoever" thing, and the "oops, no drivers either," thing, and the "extremely limited hardware support" thing. BeOS is beutiful, and if it had half the support behind it that linux has (w/r/t developers volunteering their efforts,) it would kick every other OS's ass. The fact that it's single user might be an impediment to some, but for the average user (i.e., not most readers of slashdot,) it's not a big deal. they already treat their machines as single user. (the fact that they're running Win9x helps.)

    As soon as BeOS releases whatever source it can (i know they can't release parts because of NDAs for proprietary code,) and gets whatever little open source movement behind it that will go, the better off BeOS will be. Doesn't look like that's going to happen, though.

  • Well, the DeMuDi website said it was going to be based on Debian wich means to me that they'll take the basic Debian distro and then add enhancements to it that are designed to make it more media friendly. So, unless they alter it a LOT, switching from Debian to DeMuDi should be relatively painless (though in my opinion switching distros is always painless, Linux is Linux, whether it wears a RedHat or is a "slacker"). As for whether or not you SHOULD switch over just apply the basic decision making formula you use evrytime a new distro comes out, if DeMuDi offers you more/better features for your based on your personal needs than what your using now, switch, if not, don't.
  • What about QNX [qnx.com] or BeOS [be.com]? Maybe BeOS [be.com] is a bit dead in the water, but QNX [qnx.com] is a solid and ultra fast OS that does multimedia quite well. I think that Linux is possibly a bit too fragmented with far too many different standards for sound drivers and stuff like that to be that useful. Yes, to anybody who asks, I have used some of these pieces of software under Linux.

  • With regards to all the stuff posted here about whether musicians are technical enough to pick up on this i'd agree that musicians tend to be pretty technical people as far as artists go, especially anyone who's going to take a DIY approach to producing their own music. If you're a control freak, if you're on a tight budget (isn't every musician?), and if you want the time and freedom to make your songs "perfect," it makes a hell of a lot more sense in the long run to forget booking recording sessions and spend your money on a home studio.

    Everything you hear out of a speaker is electronic music, and i don't care if you're listening to some acoustic folk guitar crap, to get that sound from your head to a recording medium you're going to need to have decent technical understanding of the tools you're using, not to mention the soundwaves you're making. The better the understanding you have, the closer the recordings will sound like the noises in your head. Anyone who's spent any time with programs like logic audio, or who's played with MIDI, electronic synthesis, or sampling, is going to have to become more technical if they are serious about getting the right performance from these tools.

    I can attest to this because I never felt any strong need to really learn about computers or electronics until I understood that I'd need something like logic audio to record the sounds i wanted. i got into pc recording about a year ago and now i'm actually serious about learning computer programming because of it (something i didn't see coming.) the control i need over sounds had extended to the tools i need to create them, and now i can't separate techological development with musical development; they're one and the same now. my guitarist friend is getting caught up with it too and neither of us were very technical people before we started with this. now we're both heading back to school to learn computers and electrical engineering. i guess my point here is that playing music can often be a springboard to learning technology if you're really serious about the sound you want. just look at guys like aphex twin or autechre or some noise musicians to see how musical and technological development are often the same thing. these are people who tweak their shit to the limit, who program, create, or modify their own tools and it shows in their music. some would argue that it's what makes them so "great" or "unique" or whatever, but no matter what it can be an important part of what distinguishes your sound.

    with regards to what i think about this linux stuff, i can say that my experiences with logic audio in windows98 has lead me to believe (with my still quite limited technical understanding) that having a linux distro streamlined for audio production would be a very powerful thing. it's not like i can use my current computer setup for much more than logic and the internet; if i install games i take huge risks screwing up libraries that it needs. i tend to max out on the 32 tracks it lets me use and when you pile on software effects you learn pretty quickly how valuable every ounce of RAM is. it doesn't take too long to realize how good getting a RAID would be when you push your hard disk to the limit on a regular basis.
