The computer used by Henke for the show, the Commodore CBM 8032, was originally released in 1980. For comparison, the microchip you’d find in today’s average domestic washing machine would be around 100,000 times more powerful that those inside each of the five computers Henke uses live on stage.
One is used for sequencing, one for creating visuals and three for creating sounds. Although he uses hardware effects from the era for filtering, pitch-shifting, looping and reverb, and expanded the computers’ capabilities with a self-produced digital to analog converter, the sonics generated are a sparse, simple combination of sine waves, clicks, bleeps and cuts.
“The sound quality on one side is very limited, it’s very rough,” Henke says. “But exactly this kind of rough, edgy sound is something that suddenly becomes interesting because we are used to perfect sound.”
