Patch 1: TCP/IP – The NIME Performance

The TCP/Indeterminate Place Quartet (see Ek et al., 2021) was formed with the intention to explore different types of interaction with the hyperorgans in the context of the Global Hyperorgan project (Harlow et al., 2021).


A modular approach was used, both to the organs and to the instruments and agencies of the quartet. The notion of an organ as a modular system enables the addition of both new controllers and sonic extensions. Here, these extensions are other musical instruments, including Robert Ek’s clarinet fitted with a motion sensor on the bell (Ek, 2024, Harlow et al., 2021), an electric MIDI guitar played by Stefan Östersjö, and Federico Visi performing with a laptop and gestural controllers. Visi’s setup navigates a sonic corpus of pre-recorded guitar sounds, i.e., sonically extending Östersjö’s guitar, and sending controller data to the organ network. Finally, the Paragraph live coding system developed within this thesis project, functions as an instrument played by me. Thus, the auditory output of a performance consists of the controlled local and remote organs (represented in speakers), the clarinet, the electric guitar, and any sounds produced or processed by the laptops. Visually, the organs have been a dominating part of the audiovisual stream due to the nature of the project, but also code projected on or next to the organs has occurred.

 

The Patch

The figure above shows the patched-up TCP/Indeterminate Place system from the perspective of the live coder. Here, Paragraph takes live input from the MIDI guitar, where each string represent a pitch in an unsorted six-note array that changes dynamically. Using this array as a scale, the live coder can write patterns that play those notes as chords or as arpeggiated phrase on the connected organs. The clarinet has a sensor on the bell that is used to control the gate length (the legato parameter) of the notes produced by Paragraph, and also controls the wind speed of the organ directly. The whole system is tempo synchronized by means of Ableton Link.

The video above is an edited excerpt of our performance that was part of the NIME conference 2021. The quartet performed from the R1 space in Stockholm, where the local Wurlitzer Cinema organ was played by means of MIDI control. In addition, the telematically controlled Utopa Baroque organ at the Orgelpark in Amsterdam was controlled over the Internet. The audio was mixed down to stereo for streaming to the online audience as well as to those listening on-site in Shanghai.

 

This video is the recording that was sent in as a proposal to the NIME conference, and was the first actualization of this Global Hyperorgan scenario. Here, the quartet performs with the Acusticum Organ in Piteå and the Utopa Baroque organ.
