panGenerator's apparatum composes sounds via digital graphic score

‘apparatum’, the installation inspired by the polish radio experimental studio and created by the panGenerator studio, comprises analog sound generators, based on magnetic tape and optical components controlled via graphic score composed with a digital interface. the device draws inspiration musically and graphically from the ‘symphony – electronic music’ composed by bogusław schaeffer.



bogusław schaeffer conceived his own visual language of symbols that conveyed the cues for the sound engineer responsible for the production of the piece. the physical form is inspired by the general aesthetics of the studio’s famous sound generator ‘black room’ designed by oskar hansen.

the electroacoustic generators and filters were arranged in a modular fashion inside two steel frames – the construction element that panGenerator has referred to in the design. magnetic tape was the primary medium used in the polish radio experimental studio. the creators also use two types of ‘tape samplers’ – two 2-track loops and three one-shot linear tape samplers. to obtain noise and basic tones they utilize purely analog optical generators based on spinning discs with graphical patterns.
