Redid the Site

I redesigned the site from scratch and just made the switch. Some content from the old site didn’t make it here, but the most popular ones should be covered.

I hope there aren’t many glitches, it’s still a bit rough around the edges; but I’m loving the new look (and functionality) so far. Drop me a line if you see something go awry and if you care enough about it.

Oscillate and Hug

Something trippy I made. Who doesn’t like geometric patterns, seriously? (It is rendered using the HTML5 canvas so you need a modern browser which preferably isn’t Internet Explorer).

Circuli – A Generative Ambient Sound Instrument

You can play with it freely by clicking here.

Here is an action video (for the iOS version):

  • Circles grow at a constant rate.
  • No two circle can overlap.
  • Bigger circle pushes and shrinks smaller circle when in contact.
  • A circle “pops” and makes a sound when its boundary intersects with the center of another circle.
  • The pitch of the sound is determined by the position of the circle on the background. Bigger the hole, higher the pitch.
  • The envelope of the produced sound is determined by a number of parameters including final circle size and time of interaction between two involved circles.

Have fun!

Otomata - Online Generative Musical Sequencer

Since its release in this website, Otomata, the generative musical toy has gained significant interest. Millions of people visited the site and played with it. I got so many mails, requests, thanks, and I’ve seen so much cool stuff people did with it and all makes me happy.

Today Otomata got an update. You can play with the new version at the exact same URL (no worries, old pieces still work), go here:

New version has an entirely new (and hopefully better) GUI, 40 cool sound scales to play with, settable tempo, and recording support (you can record your pieces as audio files from the online application and get them to your computer).

Oh, and Otomata now has an iOS version so you can play with it in your iPhones, iPods and iPads on the go. You can share your pieces through twitter and facebook with the iOS app for the world to listen!

Click here to get the iOS version from iTunes store!

As usual, here is an action video:

As the developer of Otomata, I should say that it has been a great ride so far. Thanks for all your support, and have fun!

NatureToolkit Update

NatureToolkit gets an update with Genetic Algorithms implementation. This Quark allows you to solve optimization tasks within SuperCollider. It also includes a parameter estimation system which allows you to find out parameters for a Synth to approximate an output similar to a provided audio file.

There also is a video demonstration.

deQuencher - A Live Sequencer

deQuencher is a live sequencing tool. The idea behind it is that, instead of having separate and isolated layers for musical events, you have your sound generators and gates/triggers/parameter changes share the same canvas (and layer), and you interact with your “objects” on that canvas to express your musical ideas on time domain.

Running BaudLine on Mac OS X

Those of you familiar with linux-audio hackery might know the great time-frequency analyser software called baudline. It is an amazing tool for frequency domain visualization of sound, and it also has scientific measurement tools and time domain visualization features built-in.

I explain how to go about running this piece of software under Mac OS X.
