    A newbie guide on kX's concept or "How to setup your own DSP".

    On user request I wrote a small guide which hopefully makes kX's concept
    more understandable for new users. Especialy Musicians!

    No guide can ever be complete, so I suggest using this thread for
    related user questions, comments, errors etc.

    After reading you can download latest ProFx plugins here:

    /Lex.

    ADDED;
    A less elaborate DSP guide using only ProFX;
    (for people who don't like reading to much)

    LeMury,



    This guide rocks - it should replace the docs at the KX project, in my opinion. It lets us look under the hood of the EMU chip without scaring us away with unfriendly terminology.

    I wish I would have had this guide a month ago. Still, there are squirrely things with the SB0060 card that I have that still cause one to pull out one's hair - like I can wire up Aux 2 L/R to ASIO 0/1, but it doesn't actually make the connection. I have to use 8/9 in order to get a stereo pair working for audio input on Aux 2.

    Doug W, thanks for putting the link up over at PG's forums.

    Love it. This should come with the drivers when they're installed.

    One thing though; the way the html is coded it doesn't work with different font sizes. For example if you read with a larger typeface the images cover up the text. I looked at the source and all the positions are coded absolutely.

    Strange code overall. "WEB! 2.0 Pro Extended Edition"?

    Edit: Much better now. :p

    Yes, certain CL card types like the sb0060 have this known 'ASIO Input mapping issue' which cannot be solved.
    It has nothing to do with Aux2 though.
    Any other signal source 'wired' to the ASIO Recordings Outputs will have the same issue;
    The channels 'mapping' gets shifted and some of the lower channel numbers don't work.
    The biggest problem however is when this shifting is not constant.
    Is this your case?

    LeMury - from next week i will be able to modify your code (for compatibility), and then add it to the kX Knowledgebase if you would like - zip up the folder and email to dj_stick (at) driverheaven.net - next tuesday/wednesday is when i will be able to spend some time and upload (on holiday atm), contact me if you are interested/have any special requests

    Thanks for the great guide. Really helped me get my head around DSP.

    However I do have a couple of questions if you can bear it please:

    1. Why don't I see what you say I should see? For example, your FX Bus has 30-odd outputs and mine only has 16. These are unhelpfully named (e.g. [8000] FXBus0. How am I supposed to know which are (for example) the Wave 0/1 outputs?

    FX BusX gives me lots more outputs but they're no more helpfully named. Which majes me wonder what exactly IS the difference between the various almost-identical plugins e.g. FXBus & FXBusX, routing & xrouting etc.?

    2. Why don't I hear anything? I've set up a basic DSP configuration just like your one in the guide, I've a sound source playing to KX Wave 0/1 and I've attached each FX Bus output in turn to the stereo mix in but get nothing at all. The problem isn't elsewhere, as when I re-initialize DSP and enable 4.1 speaker mode with surround copy, I get sound straight away. I'm so confused :duh:

    3. Where do I find the ProFX plugins? They aren't showing up in my menu. Do I need to download them seperately?

    I'm using KX v3534 with an original SB Live ct4620
    I think something's very strange with my setup, it just doesn't seem to be working like other people's - would love to find out why.
    Cheers again, if I can get over these setup problems I can see I'm going to have something amazing to work with.

    1. The sound card in your computer doesn't support as many outputs as newer cards. As far as the names of the outputs, that is all handled on the "router" page, which needs its own guide IMO. :sigh:

    2. You need to check the signal every step of the way. Connect "peak" to the fxbus at 0/1 and right-click,tweak it. It'll show you a volume meter so you can see if sound is actually coming out of fxbus. (This is a good trick to test anything really.) Also make sure your speakers are connected to the physical port that the signal is routed to.

    3. My guess is your sound card doesn't support them, but I dunno. :hmm:

    The pro fx are not included in 3534. Install the latest version or 3537.

    The numbers of the fxbus outputs correspond to the wave devices (for instance fx bus 4 and 5 are left and right of wave 4/5).

    >>Why don't I see what you say I should see? For example,
    >>your FX Bus has 30-odd outputs and mine only has 16.
    On 10k1 cards like yours, the FXbus has 16 channels.
    on 10k2 cards like mine, the FXbus has 32 channels.

    >>These are unhelpfully named (e.g. [8000] FXBus0.
    >> How am I supposed to know which are (for example) the Wave 0/1
    >>outputs?
    You can find/change the signal mapping of the FXbus in the 'kX Router applet'.
    (I didnt mentioned this in the guide anymore just to keep things simpel,..hmm maybe I should do that again)

    >>Which majes me wonder what exactly IS the difference between the
    >>various almost-identical plugins e.g. FXBus & FXBusX, routing & xrouting
    >>etc.?
    Don't bother yourself with fxbusx and xrouting.
    Just use FXBus.

    >>Why don't I hear anything? I've set up a basic DSP configuration just like
    >>your one in the guide, I've a sound source playing to KX Wave 0/1 and I've
    >>attached each FX Bus output in turn to the stereo mix in but get nothing
    >>at all.
    -did you forgot to open (doubleclick) the stereo mixer and turned on its volume sliders?
    -does you front/rear speaker setup output match with Epilog?

    >>Where do I find the ProFX plugins? They aren't showing up in my menu.
    >>Do I need to download them seperately?
    Bummer,..the ProFX plugins are not included in 3534f.
    Only in later driver versions.

    >>I think something's very strange with my setup, it just doesn't seem to be
    >>working like other people's - would love to find out why.
    There's nothing strange going on, just some extra tweaks and some learning,
    and you'll be set.

    Great Job, it seems that I have to spend some time to translate it into Chinese.thanks again.

    OK, but be aware that this guide is still in 'Concept fase'.
    Depending on user response I may re-write it to make it more
    readable/understandable/simpler.

    Yeah I guess so. Still need someone to correct typos, spelling and grammar though.
