WikiMixing at Megapolis!

Next weekend I’m presenting a workshop / audio art experiment at the The Megapolis Audio Festival in Baltimore.  I’m calling the workshop “WikiMixing,” and I’ve set up a separate page about the project at www.drivebyhighfive.net/wikimixing. I’m mirroring it in this blog post:

Mixing on a computer is usually a solitary endeavor: one person controlling one mouse and keyboard making one decision at a time. We’re going to try to fix that. Part workshop and part experiment in “crowd-sourced” audio art, this is like editing Wikipedia but with sound instead of text. Participants will be asked to provide four short sounds with four different sonic characteristics. (Details below.) We’ll import all these sounds into a computer and collectively mix and manipulate them as a group in real-time using a bunch of colorful customized keyboard controllers, all connected to a single computer. The idea is to get as many hands/ears/minds at once collaborating (and competing) on the same soundscape, so that whatever strange, beautiful, or frightening noises that emerge are the product of our group’s collective will. Everyone is in control at the same time and yet no one is! NO prior audio software experience is necessary; everything you need to know is on the keyboards. (Pics coming soon!) Recordings of our experiments will be available immediately following the workshop.

About your four samples…

I’m asking for you to do a little bit of homework. I’d like you to send me four different sounds that are around 5-30 seconds long from each of the four categories below:

1. An ambeince (background or environmental noise e.g. the sound of a forest, ocean, busy street, etc.)
2. Some sharp, transient sounds or a series of percussive/rhythmic sounds
3. A longer sustained and/or evolving sound
4. Something musical or melodic (or anything with a distinct tonality)

The idea is to have a diverse palatte of sounds, so don’t worry if your sounds don’t exactly match the categories. Sounds can be acoustic, synthesized, or anything between. Surprise me! (Bonus points if they are in stereo.) I can accept WAV, AIFF, or MP3 files.

Naming and uploading audio files

Please format your audio files like this: [short description]_[category #]_[your name].wav

For example:

• brooklyn_playground_1_brendan_baker.wav
• radiator_clanking_2_brendan_baker.wav
• ambulance_echoes_3_brendan_baker.wav
• ice_cream_truck_4_brendan_baker.wav

You can send me your audio files ahead of the festival two ways: email or FTP. (While it may be possible to import a few people’s sounds at the beginning of the workshop, it will be MUCH easier for me if I can load them beforehand.)

• Email: wikimixing [at] drivebyhighfive [dot] net
• FTP Server: “ftp.drivebyhighfive.net”
• Login/Username: wikimixing [at] drivebyhighfive [dot] net (same as the full email address above)
• Password: megapolis

I realize I’m asking a lot, so thanks in advance for humoring me with all this. It will be totally worth it!

Cheers,

So what will this sound like?

Who knows?! It could sound like almost anything depending on what samples you bring, your own sonic tastes, and of course the tastes of everyone else in the workshop. I do, however, have a couple test examples using a few samples of my own. The example starts off with me hitting keys randomly, but it might give you an idea of the variety of possibilities. My hope is that some sense of order will emerge from the input of our entire group making (non-random) mix decisions at the same time.

WikiMixing Prototype 9

And here’s an older test, before I finished building the MaxMSP keyboard controller patch as it currently stands. It’s a little rougher. The samples in this one are mostly animal sounds and ambient music.

WikiMixing Prototype 8

I’m a geek. How will this work?

I’ll have 14 USB computer keyboards all plugged into my laptop via two USB hubs. When I first thought of this, I was imagining using real MIDI keyboards with knobs and sliders…but at $50-100 bucks a pop, that wasn’t gonna happen. USB keyboards, on the other hand, can be had for as little as $5 each–so I can hack them apart and paint them without too much worry.

I built a MaxMSP patch that translates keyboard typing to MIDI control change (CC) data. This is what the patch looks like:

This is what the patch looks like under the hood:

Those are just the guts; don’t let that scare you off. Here’s what it looks like on the outside:

Much better, huh? Basically it’s like a 4-track mixing board but with some extra sonic goodies.

I’m still painting the controller keyboards, but they’ll look something like this:

So the computer keys control each one of these parameters on the “4-track.” For instance, “z” and “x” make the blue volume slider move up and down, the F1-F12 keys turn the various effects on and off, and MaxMSP spits this out as MIDI data. I’m also going to label each key’s function on the actual keyboards. Someone with better programming skills than me would be able to make the whole WikiMixing project entirely inside MaxMSP, but this aside, I also didn’t want to reinvent the wheel so I’m routing this MIDI data into a program called Live by Ableton.

An aside: You don’t need to be familiar with Live in order to do WikiMixing, but those who are might “get” what I’m trying to do and how I’m doing it a little easier. That said, if you’re interested in electronic music and not familiar with Live, you owe it to yourself to check it out. I find people coming from a “serious” electronic music composition background scoff at Live as being a toy for DJs and 4/4 beatmakers. Live can indeed do these very easily (and elegantly), but it can do so much more. Live is one fine piece of software design. Check it out if you haven’t.

I load everyone’s samples into Live, with one track for each sonic category. And then we play with it. Fun!
