    Default Quartz Composer doodling

    Hey guys,

    Since I'm sick at home right now I had some time on my hand to wrap my head around this whole Quartz Composer thing.
    I saw Joachim Garraud explain it in his first Invasion-Video, but I never got around to looking how to really build this.
    Anyway- what I wanted to build was an interactive visualizer to playback to my live-sound. I accomplished that, but after understanding what Quartz is capable of I kind of what to go even further. I'm thinking about using videos and stuff, but that's a bit of a future project right now. What I've done right now is a small patch with some basic graphical equalization.
    I'll see what I can learn in the next couple of days, perhaps I'll get an improved 1.1 version up then.
    From what I can say now it should work the following way- open the file with quicktime, set input-device to the line-in/mic-in that your tunes are coming from and drag the visualizer onto your screen, maximize it... done.
    I mix stuff on my things...

    To be honest- I haven't thought about that, but you could try opening it using Quicktime. Thats the way it should work.

    There you go- hope this gives at least an impression of what it does.

    Yes, I'm using Traktor and generating my the visuals dynamically on a second PC.
    I was specifically looking for a on-the-fly solution to generate visuals for my mix that don't require a VJ or switching to a complete solutions and rebuilding all my songs with videos.

    Default great job!

    im at work and i thought id try it. great job man! here is a pic of it running on my MBP. It used QuickTime7, and i needed to turn the input to the internal microphone in system prefs. it heard the booth monitors while im djing on cdjs. the balloons-lines thing is sweet. i was playing Martin Solveig at the time.

    Yeah, I'm experimenting with it right now:
    Revised instructions for best result is-
    - Download xCode 3.0
    - Open Composition
    - Click on Viewer and toggle that window to Fullscreen
    - To change the input, simply go to your Audio-Preferences and declare your Line-In the standard-systemwide input
    - That worked for me (to hear Line-In you normally need to open Quicktime, select a "New Audio Recording" and pull the Audio to full)

    I'm uploading a screen-grab I just did right now, it doesn't contain mixing, just some playing around with filters and levels, so that you can see the way the Visualizer behaves.

    EDIT: Screengrab is up.
