The electronic audio-visual trio SKIF++ is a collaboration of Jeff Carey (laptop SuperCollider), Robert van Heumen (laptop LiSa) and Bas van Koolwijk (laptop Max/MSP/Jitter). Sound gets processed into video and back, ranging from sonic bursts to melodic melancholy, using joysticks and selfmade controllers to keep it all in line (most of the time). Every SKIF++ performance is improvised, but based on structures that give each set its distinct character.
The SKIF++ video is generated live with a digital application that was inspired by the workings of the 1972 Rutt/Etra scan. processor The Rutt/Etra scan processor was essentially an analog computer which allowed for electronic real-time manipulation of the deflection signals that generate the television raster. The SKIF++ digital application uses audio signals for input and scans the incoming data to produce its characteristic graphics, delivering a very tight connection between the three players. The SKIF++ audio is generated by SuperCollider3 and LiSa X Ð SC3 delivers highly complex synthesized audio blocks while LiSa takes care of magnifying sampled material into territories unknown - all in a highly responsive environment. While the interaction from audio to video is digital, the counterpart is the musical response of the players to the green thing projected on the screen.
