 All right. Hello, everyone. My name is Hansi. I come from Austria, from Linz, and I'm going to talk about how to use Blender to make music. First, I want to give you some backstories. So, a work as a freelance programmer, which means I often get to work on very strange projects. So, this was in 2012. That explains the resolution also. And it was the startup company that wanted to make tables which you can print on. So, you upload your own images so you could work with SVGs. And they wanted to preview how the tables would look in a nice style. And at this time, there was no way, really, without Flash, which wasn't allowed to use, to do this in a browser. So, I did some research, and I looked at all the big 3D applications. And nothing was really feasible except Blender. So, this is how it came out in the end after you uploaded your images. And it worked really well. I mean, I had no idea of Blender before. I just started looking at the Blender cookie tutorials and learned how to script it. And I think I had the basic system running in half a day, which really impressed me. And then I started to get very addicted to Blender. So, even after the project, I would always watch the tutorials during eating and before going to bed. And I made a lot of silly things. So, this is a video of a cuttlefish. I didn't know what I was doing. Just something with the deform. Yeah, it moves nice. And I liked it. Then I did the nose flute 3D model. It's when people snore, you can put it in their nose and they make music instead of snoring. It's very useful. Maybe it will be 3D printed one day. I made this website. It's called Beyond Today. It concerns itself with the digital afterlife. So, you see the Blender model. Which button is the laser pointer? Yeah. So, this is the Blender model I made. It's a chip you put in your leg and you connect it to your artery. And it uses this as a generator for power to load a battery. And then when you die your bloodstream stops and it can upload the message to Facebook where you say goodbye to everyone. So, I mean for me really any excuse was good and I just really got into Blender. So, this was maybe some point in 2013 or something. And then I went to this place for the first time. This is Halain. It's a tiny town in Austria. And it's an old salt factory that's not in use anymore. So, once a year, I think since almost 15 years, they have this festival. It's kind of small. It's two to 300 people and it's a big mess. So, there's dancers, there's musicians, there's programmers. I don't understand the concept but it's good fun to go there. This is the big work space where everyone sits. It's called the wood. There's lots of wood. And then I met this guy, Chris, the mean looking man. And he at this time was working on oscilloscope music. He called it. Because he's an audio engineer. And before I explain too much about it, I'll show you what he showed me then. And I'll just show you an excerpt so it doesn't get too long. I'll just show you the first minute. You have to go on the web to search for it. It gets quite more musical later but I think I'm in a hurry already. So, let's not spend too much time. So, what's going on here? Who knows this device? Who has used this before? Oh, this is good. So, I skipped this really fast. I didn't expect this. So, yes, it's an oscilloscope. It has this big thing on the side and it switches it to X. You can switch it to XY mode so you move a dot. You can put, this is when you turn it on, you get the, oh, sorry. Once more. Okay, so you turn it on, you get the dot and you connect any signal, like a battery, your power outlet or music and it moves the dot left, right. You connect something down here. It moves it up, down. So, we go faster because everyone knows. So, I made some demos because I couldn't bring the oscilloscope here. So, I'm playing some audio. It's so low. You can't hear it. It's one hertz. Moves the dot up and down. We make it faster. Now you can start to hear something hopefully. Yeah, on just one side. When you have the same signal on both channels, you get a diagonal line because X and Y move in sync. So, you erase a little chunk and then that's where the fun begins. I mean, then you can get ellipses and circles depending on how much you erase from the signal. Am I going too fast? Okay. It's even more interesting when you do things like you double the frequency of one of the channels. You get this figure eight and those are called Lisa Shoe figures and that's what you saw in the video before and you can get very expressive and you can do a lot of things with this. So, anything that vaguely looks like this, kind of like a nice, I call it a long square, you can do. And the mathematical term is the parametric equation. And it's really good to do abstract things, but it makes it kind of hard to do concrete things. So, Chris showed me this and then we didn't meet for a year and a year later we met again at the same place and I had used more blender and then I kind of had this idea that you could reverse the process. So, here I'm showing how to reverse the process. So, you see I'm just moving my finger like this and then on the left and right and bottom you see how the wave should look that you end up with this shape. So, you're just thinking the other way around. You think about the image and you generate the sound. Of course, with a spiral it gets bigger and with a rectangle or triangle it would be very rectangular and you also hear this difference. So, of course, the natural thing to do because I was so into blender at this time was to see if I could hook this up to blender and it worked. I think it took me only three days maybe to produce this. This was the first successful test. It's just some walking man animation I found on Blendswap.com because I didn't know I forgot blender to do rigging still. So, then we worked on this a long time, Chris and I, actually two years and this is the first version of the application. You see it's even upside down. I didn't care. You see blender in the background and there's this application. They communicate over network and it sends over the data and in this tries to find a path. The colors somehow they know how which path was found through the mesh and worked on it a lot more. It got like features to get multiple groups and edit support for Bessia curves which are really nice to edit in blender. It's pretty good editor for this, I find. And then this was beginning of this year. I changed my mind and made it look very different. I find audio applications must be dark. Why they're not taken seriously. So, I made it very back. And now I'm going to give you a very brief. I'm trying to keep it to five minutes. Demo of how the application looks now and how it's used in conjunction with blender. It's okay if I remove the screen. So, I have a chair. Maybe I can take one chair. So, the application was released three weeks ago together with this music album, oscilloscope music. That's the title of the entire project. And the application is called Aussie Studio. So, you open it up. You're greeted with an understandable setting screen. And you pick the audio. So, this is how the application looks. And then you also need blender. And I have it preloaded already. So, there's a plugin down here. Press this. And then it sends over the data. And now you can work with this mesh data in a music way. Any change you make. Interesting thing about it to me is that you live in between the words like you change the geometry. It changes the sound. You change the sound. It changes the geometry. So, here if I activate this, this by the way is a total ripoff of blender's modifiers. I decided it's a good idea. I'm going to do the same thing. So, here I'm just removing most of the model I'm showing some parts. Here I can turn it into a grid. Then, of course, you always... Oh, I'm going to show you my favorite. Let's disable this. My favorite is the ball. It turns everything into a ball. And of course, you can animate all these parameters. There's this timeline view. Do you see in there? The frequency. That's also interesting. Changing how fast it runs doesn't change the image. Just one degree of freedom you have. You can modulate the signal. I have a million videos online of me messing around with it. So, I think it's good enough for a demo. I already say goodbye. I almost say goodbye. That's the website. It's also the entire album that Chris made. He's actually the one doing the music. It's linked. It's a YouTube playlist. You can just watch it. It's a website. I don't really have a website at the moment. So, it's just my YouTube where I upload all my mess unfiltered. I'm going to leave you with a video that's three and a half minutes. It's one of the tracks of the album that was made completely with the soft wind blender. Remind you, it's the audio you're seeing. It's not visual. It's the audio. All right. There's a few more things I want to say. Thanks to the Blender community, especially Olsen. I don't know how he is. He's an IRC and he always helped me with my programming. Is it you? No. I don't know who he is. Also, thanks to Open Frameworks. It's this C++ programming library I've been using for all of this. And Blender Cookie, I've had some good times on their YouTube. Is it CG Cookie now? I never understand. Anyways, thanks.
