Here’s what we’re after: 3 different videos mapped all over some cubes:
Madmapper 1024p download#
You can download the MadMapper demo here: MadMapper website The principle is here, now hook up your projector and start mapping.Hi, in this tutorial we’ll use Modul8 to input multiple video sources in MadMapper. Since the QC content is white, we can use MadMapper to modulate the color of each quad. Now make 4 quad surfaces, each selecting a different portion of the input, like that:įinally, you can work on your mapping and modify the perspective of each quad. We’ll be working with squares – original isn’t it ? – Modify the parameters like that (no need for a huge resolution): Launch MadMapper (version 1.4 minimum), import your freshly saved QC file, and select it to activate it in the input view. Bravo, you’re now officially an Audio-Visual Performer. If Ableton Live is still running and playing, the sprites should blink according to the rhythm you just made. Since QC is working with normalized floats (0.0->1.0), the Midi velocity (range 0->127) is automatically scaled to the sprite’s color (range 0->1). Then connect the notes receivers to the color pins of the sprites, like that: I made them sized 1 by 1 unit, positioned at Zuper-easy.ĭrag 4 sprites, position them in each corner of the QC viewer. The next step is to add 4 sprites whose brightness will respond to the velocity of the midi notes sent by Ableton. Middle note is now C3 in QC, and we listen to the C5 note range.
Madmapper 1024p Patch#
So for both apps to be on the same page, we’ll have to configure the MIDI Notes Receiver patch to Middle C3, just like that: QC defaults the middle note to C5, but Ableton Live is C3. This sounds over complicated, but apparently it was causing problems in 64bit (see comments).ĭrop a Clear Patch (bule) and a MIDI Note Receiver Patch (purple). Then start Quartz Composer and make a blank project. Locate quartzComposer, make sure it runs in 32bit, by right-clicking the app, select “Show Info”, then select “Open in 32 bit”. Wow, the Ableton Live part is over ! Keep the app open and playing. Note that you can put any other synth you want … Here are the settings (shown when clicking the black arrow at the very right bottom of Live window):Ĭlick the play buttom and you should have some sound magically coming from your speakers, since we dropped an instrument on the “Midi to Audio” track, namely a bassline. This instrument will actually produce the sound of our project. We’ll use 4 notes for this tutorial (but you can use more of course),ĭrag an instrument (I’ve used a Bassline from the analog library) on the “Midi to Audio” track.
Now we’ll make some notes to drive the visuals. (the black arrow at the very bottom right of the Live window). (right click, insert midi clip), like that: Now we have to set the correct midi inputs/outputs for the tracks.Ĭongratulations, the boring part is done.Ĭreate a new midi pattern in the ‘Midi to QC” track Just to be sure, go to the Preferences (in the menu), then select Midi, then set your midi ports to enable IAC bus: Let’s configure the Midi so that everything works. This track will use the first midi track to get its data from and generate some sounds. Rename the Midi track to “Midi to QC” – with this track we’ll send midi data to QuartzComposer.Ĭreate an extra Midi track (CMD + SHIFT + T) and rename it to “Midi to Audio”. We won’t need the audio track, so select it (click on its title) and get rid of it (press delete). Great, you just have an IAC loopback bus configured.īy default when creating a new Live project, you have 2 tracks, one Audio track and one Midi track: Then select and double click the IAC box and enable the bus (check “Device is Online) In the menu, select Window / Show Midi Window. Go to your /Applications/Utilities folder, and launch the “Audio Midi Setup.app”. On the Mac, there’s a loopback allowing to share Midi data internally.
Madmapper 1024p free#
Which is widespread and hopefully free with every Mac. Since we’ll be using audio to automatically sync the mapping, we’ll use the MIDI protocol, The idea behing this tutorial is to use Ableton Live as a sequencer to drive realtime Quartz Composer graphics, mapped using MadMapper.įor this tutorial, we’ll pass some information between different applications. (scroll to the end of the tutorial for a video) This is the end result you gonna get when finished:
