Radiator, New Portable Laser Synthesizer For Live Performances Now On Kickstarter

SYNTH ANATOMY uses affiliation & partner programs (big red buttons) to finance a part of the activity. If you use these, you support the website. Thanks! 

Andrew Kilpatrick, developer of the Phenol Synthesizer teamed up with the laser artist Christopher Short & designer QP Tharmviboonsi and developed in the past months the Radiator Laser Synthesizer. Radiator is designed and works like a music Synthesizer. It contains modules that will be familiar to both electronic musicians and computer graphic artists alike. It contains shape generators, color generator, transformer (2D to 3D), clones, modulators as well as a master section.

Very interesting is here that you can design laser visuals like sounds on a Synthesizer. Radiator brings what we like all (tweaking knobs) in the laser & visual technology. Important to know before pre-ordering: you need a laser device to use it. Nonetheless, a very nice new project of the Phenol designer. In my opinion, it’s a powerful but affordable tool for musicians and visual artists.

Back at the dawn of the laser show industry in the 1970s, laser shows were mainly controlled by skilled operators called Laserists, usually coming from an arts or music background. Laserists would literally perform each show live, usually to a pre-recorded soundtrack. Each show was different, dynamic and exciting. Fans would attend the same show over and over, since each show offered a unique experience just like a live music performance.

But as computer technology evolved, laser shows became more automated and lost their spontaneous performance qualities. Instead of a skilled performer, the job of Laserists was mainly that of a technician tasked with running and maintaining the equipment. Radiator aims to bring back the live performance aspect to laser shows and once again make the job of Laserist synonymous with a performance artist.

Radiator is a complete laser synthesizer which means that it contains everything necessary to create beautiful live, spontaneous vector and laser graphics, except for the laser projector itself. The performance controls, processing, and all other functions are built-in. The output of Radiator connects directly to a laser projector using the industry-standard ILDA connector. This carries signals for moving the laser beam and controlling the color.

Radiator works like a music synthesizer. It contains modules that will be familiar to both electronic musicians and computer graphic artists alike. The modules work together to give virtually limitless possibilities of control.

The following are the major parts of Radiator:

  • Shape Generators – This is where beams, abstract and other shapes are generated. The most basic settings give you the traditional sine and cosine waves that started the laser show craze back in the 1970s! Mix two waves together to make beautiful cycloid or Lissajous patterns. Other shapes give you even more complexity, and we hope to allow you to design and import your own shapes and line-art animations as well.
  • Color Generator – The color generator selects the beam color, either a single hue or complex cycling color patterns. The Color Generator knows how to synchronize with shapes and other modules to create images with smooth fades and evolving colors.
  • Transformer – This is where 2D becomes 3D! Shapes and colors are mapped into three dimensions allowing you to add motion, depth, and rotation.
  • Clones – Repetition is beautiful, and that’s exactly what the clones module does. It allows images to be repeated in various ways such as in grids or radially. The result can then be moved and rotated to create dynamic and stunning images that appear to have a life of their own!
  • Modulators – Did we mention that nearly any control can be modulated in real-time? That’s right! It’s like having more hands! Each of the three modulators can affect controls on any other module. Want to have a shape get bigger and smaller? Or how about make the brightness fade up and down while also rotating the image? You can do it all with the Modulators. External MIDI and CV sources can also be used as modulation sources.
  • Master – Safety is of the utmost importance with lasers. The master section offers direct control of the size and brightness of the beams. A blackout button kills the beam instantly. If you need to step out for a moment, the safety interlock key switch ensures that nobody will activate the laser when you’re gone.
