The demoscene (usually shortened as “scene”) is an artistic movement where different artists (programmers, graphicians and musicians) work alone or in groups to create digital art. This section contains the works I made in the demoscene from 1998 to 2005, under the handle Yero. I have produced works in the main areas of the demoscene:

  • Code: for Sector Omega, a Spanish demo group;
  • Graphics: for 2D GFX competitions in demo parties and also for Sector Omega;
  • Music: first composed for national tracker scene contests (under Sound Factory, a Spanish tracker group), then for warez (BAFH, European warez group), and for demos (for Concept, a Spanish demogroup).

I also participated in a couple of Musicdisks, which are compilations of several tunes with a specially-designed interface (code and graphics). I also participated in different projects related to the demoscene, such as, a relatively big amateur music portal (1200+ artists), where I was the director, programmer and designer from 2000 to 2012. I was also co-developer of the Spanish report system, together with Wizard, an online photo manager for parties.

Demos (aka realtime motion graphics)

A demo is a real time calculated multimedia presentation, which often includes 2D art, 3D animation, visual effects and a musical soundtrack, everything coded, designed and composed by the members of a demogroup.

I entered the demoscene in year 2000 as a musician for some European groups and later for the Spanish group Concept. In 2003 I founded Sector Omega, in which I left music aside and acted as a coder and 2D/3D designer, together with the direction of the productions. The well-known JosSs joined the group as a musician.

In this section I include the four demos we developed from 2003 until 2005. In order to see the demos you can either download the executable (for windows) or watch the video when possible. And remember, everything is calculated in real time.

The message

A space story, a tribute to Dr Carl Sagan. Uses 3D animations, nice soundtrack, several improvements in the 2D fx, and a solid plot. A lot of work was put in this demo, specially on the coding engine.

This time with an evolved demosystem ready to make something new. We thought about making some japanese alike demo, with fast effects and techno music. Finally, another ambient soundtrack, but with some electronic parts, synched with better effects and lots of graphics.

Co-op with Stravaganza demogroup. As our demosystem was not much improved since Mirages, we asked Ithaqua/SGZ to be the coder of our graphics and soundtrack. And this is the result. Quite simple 3D architecture, with some cool effects, and a lovely soundtrack.

First demo by Sector Omega. Coded in a couple of months, in a real hurry, with a very simple demosystem. It talks about dreams, the mirages of life, which are supposed to be reached someday.

This section contains the music I composed mainly with Impulse Tracker. I started composing in 1996 and stopped around 2003, when I founded Sector Omega and spent most of the time democoding. I grouped the modules in four files, in which I include the music from different periods. In order to listen them you’ll need a module player since they are mostly in .IT format, not in mp3. So try with xmplay for Windows, or Schism Tracker (an Impulse Tracker clone) for Win/Linux/MacOs, etc..
