    Cross-Art Live

    Dec 2018.

    Karl Heding: Musician and composer

    SPACE ECHO (Sam Sernavski / Karl Heding)

    Performance at Øbro Jagtvej Bibliotek , Copenhagen Denmark as a part of the interactive new media art event "SYNTETISK" on 14th of May.

    Live Improvisation with audience participation. Members were given access to WiiRemotes acting as MIDI controllers to various Digital Instruments. Enabling even audience members without any prior musical training, to participate in the performance and improvise the music with the musicians.

    Interface Design for "SYNTETISK"


    I was responsible for the Design of the Sonic and Visual Interactive Interfaces for the event SYNTETISK.

    WiiRemotes are used as MIDI interfaces that control the sound parameters of various Digital Musical Instruments created in Ableton Live. The WiiRemotes are also used as controllers of visual processes in Processing.

    Acoustic Guitar Augmentation


    Guitar processed in SuperCollider . Sounds played back through sound-drivers (vibration speakers) attached to the body of the guitar. An integration of acoustic and electronic sound in one single instrument.

    Inspiration from Otso Lähdeoja. My appraoch makes use of a single-coil pickup, it does not provide the numerous advantages of using hexaphonic pickups (as seen in Otso's work). However, I believe it makes for a more acessible solution for the interested musician.

    In the video all the recorded sounds were emanated from the guitar's body. No post production.

    Musical result heard in SoundCloud.

    Sympathy For The A.I.


    Performance at Mørke Dage.


    let there be fire

    set in a decommissioned bank vault.

    "... consists of thirteen small pieces all surrounding the same theme and together becoming one total installation that delivers a metaphorical world where economy is represented by fire and the flame with the currency as fuel for that fire." Art & Technology




    March 2018.

    Piece created for Sound Photography by Cities & Memory.

    The biggest ever worldwide artistic interaction between photographers and sound artists, covering 34 countries and six continents with sound pieces inspired by photographs.

    Photography: Emma Courtland - Sathani Rotfai Krung Thep, the main railway station in Bangkok.

    "I wanted this piece to contain a soundscape interpreting the space in this image, reflecting on the architecture and it’s aesthetics. With music inspired by traditional music of Thailand such as Piphat and Mor Lam, celebrating the many passengers and their journeys. The composition uses guitar, field recordings (crowd), analog synthesis and sound processing to reimagine the sound of trains and the instruments used in Thai music."

    telegraph pole


    These are a series of sonic pieces done as part of ’the fencepost reclamation project’.

    Various artists provide sonic reinterpretations for a series of field recordings.
