Membranes is an audiovisual installation and performance by NHLT, a duo from Switzerland and Germany. It consists of hybrid instruments – constructed from drum-skins and electronic components – as devices to turn written texts into pulses of light and percussive sound.

Michael Vorfeld’s sounds are generated by different light bulbs and actuating electric devices, and the rhythmic variety of the flickering and pulsing lights is directly transformed into a comprehensive and microcosmic electro-acoustic world of sound. Using Harvestworks’ new 8-channel sound cube (with 4 speakers each situated on floor and ceiling), Hans Tammen’s Prozesshansl software moves these sounds in three dimensions to create fragile and contrastive soundscapes surrounding the audience.

Hans Tammen performs “Conflict of Interest”, sonifying his own personal genetic analysis. Written for the Endangered Guitar, a hybrid interactive software/guitar instrument, this data set controls sonic processing as well as 8-channel spatialization in realtime.


The material for BRUCHHARSCH was created at a residency at Signal Culture in May 2017. The audio synthesizers were set up first, and control voltage from those synths playing was used to influence the video synths.


The underlying idea of Clepsydra is to draw from electronic music experience to write for chamber ensemble, and “Sample And Hold” techniques provide rich material to draw from.

Take part in a massive ensemble of electronic instruments! Using flashcards and hand signs, Hans Tammen has worked with large ensembles using electronic instruments for way over a decade. As part of this year’s Make Music NY at NYU, we will work with any electronics that make sound.
