Concert Line up

Day 1 - Thursday, April/9

Concert

20:00 Topos Concrete
Clemens von Reusner » Location: Roter Saal

The territory (gr. topos) is a rough and harsh landscape with mountains, valleys, canyons and plains, sand and stones, though it appears evenly and smooth. The color is grey. The size is about 30 square-meters. It is the floor of a garage and it is made of concrete (engl.) / Beton (german).
Concrete is a building material, a kind of unshaped dry powder made of sand, granulated stones and cement, dusty and chaotic. Mixed with water it becomes flexible and fluid and goes into a metamorphosis to become dry again, static and resistable and of any wanted shape. Aspects of working with native granularity, fluidness as well as stiffness and different kind of acoustic spaces were leading ideas of the composition. Software: Csound, Sox, SuperCollider. The csound 3rd-order ambisonic opcodes by Jan Jacob Hofmann were used for multichannel spatialization. -- Premiere --

Day 1 - Thursday, April/9

Concert

20:00 Klinga
Helene Hedsund » Location: Roter Saal

The sound material in Klinga is made up of recordings of an old saw blades being hit and scraped by various objects. The piece, and all sound processing is made in an instrument built by myself in SuperCollider.

Day 1 - Thursday, April/9

Concert

20:00 Benjolin
Patrick Gunawan Hartono » Location: Roter Saal

Benjolin is an electroacoustic composition for eight-channel speakers, in which all the sound materials that have been used are the result of the Benjolin synthesizer designed by synth pioneer Rob Horddijk.

The compositional structure is intuitive based on gradual and dramatic dynamic changes, which are represented by random pulses and square waves as offered by Benjolin.

An open-source 3D sound algorithm was implemented for the spatialization structure of this piece, which has been realized in the SuperCollider environment.

Day 1 - Thursday, April/9

Concert

20:00 Voce231114
Massimo Fragalà » Location: Roter Saal

All the sounds that form this composition derive from the elaboration of word splash that myself recorded. Starting from this sample I tried to change the physical characteristics in order to generate a range of sounds more or less different compared to their original variety. This was possible using particular technique of sound processing such as waveset distortion, brassage stretching, segmenting the sound and reassembling segments, reverberation, etc. This composition has been realized on linux kxstudio.

Day 2 - Friday, April/10

Concert

20:00 speaking clock
Mari Ohno » Location: Roter Saal

This work is an electroacoustic composition created with the recordings of speaking clocks in various sites around the world. A speaking clock is a tool of sonification of "time", a phenomenon people cannot hear. It has various expressions of time depending on the country or region. In this work, the music mixes various expressions of time, based on the concept of "the expression of time perception". Through this work, I attempt to give listeners curious and unique feelings through the same sound experience depending on their cultural background.

Day 2 - Friday, April/10

Concert

20:00 Selva di varie intonazioni
Michele Del Prete » Location: Roter Saal

Csound, tape music, 8 channel, 9'.54", 2013
The piece is based on concrete sounds I recorded in the Frari church in Venice, a building that hosts two notable organs of the XVIII century. I have recorded their stops (as well as key noises) individually and in several combinations, thus already obtaining a very rich timbral material I have later worked on exclusively in Csound.

Day 2 - Friday, April/10

Concert

20:00 The Hidden and Mysterious Machinery of Sound
Fernando Lopez-Lezcano » Location: Roter Saal

I had been thinking about a piece that used simple sine oscillators in complex ways for a long time. Going back to basics, in a sense. With that idea in mind I dived into the innards of Bill Schottstaedt's new Scheme-based version of the CLM synthesis language and its s7 interpreter, and stumbled into new ugens that allowed me to pile sinewaves in many different ways. The "imaginary machines" examples I found there also helped shape the first code fragments I experimented with. What remains of many lines of discarded Scheme code is the program that writes this piece. It creates fractal machines that manipulate clockwork mechanisms, big and small "virtual gears" that interlock, work without pause, and drive the basic sound synthesis instruments. This universe of miniature machines is spread over 3D space using Ambisonics, and the resulting soundscape is made of interlocking patterns of sound that drift through space. WARNING: the piece contains repetitive phrases of sound (also known as "rhythms"), and is only intended for immature audiences.

Day 2 - Friday, April/10

Concert

20:00 Coloured Dots And The Voids In Between
Jan Jacob Hofmann » Location: Roter Saal

In the piece "Coloured Dots And The Voids In Between" spatial textures of dot-like sounds occur. The fields created by that expand and evolve in space and time. Important are not only the events of sounds themselves but also the spaces in between these, which expand in different dimensions spatially and temporally, overlap and thus create the actual space. All sounds have been generated using solely the "pluck"-opcode, which simulates the sound of a plucked string.

The piece is spatially encoded in 3rd order Ambisonic and has been created with the program "Csound" and "Cmask" along with Steven Yi's environment for composition "blue" using the self-conceived editor for spatial composition "Spatial Granulator".

Day 2 - Friday, April/10

Concert

21:30 Embedded Artist
(30 min) Wolfgang Spahn, Malte Steiner » Location: Installation Space

Industrial noise and digital sound processing meets multi space projections: "Embedded Artist" is a media performance by Malte Steiner and Wolfgang Spahn. The performance combines four different layers of visions that are merging into one visual Gesamtkunstwerk: 3D models, video scratching, live camera, and mechanical effects are likewise projected within the space. "Embedded Artist" is not only projecting all over the walls, but it is filming the audience and the space and re-projecting those images. Moreover, the light beam of each projector is fractionized by a prism and therefore sends broken images onto the walls. For the performance both artists developed a system for multiple embedded systems. To achieve this the following software and programs are used: Pure Data, Raspberry Pi, Raspian, and Python. As hardware components several Raspberry Pi's were combined with Paper-Duino-Pi's and remote controlled via OSC from the performers laptops.

Day 3 - Saturday, April/11

Concert

20:00 Spielzeug #1 - poco a poco accelerando al sinus - for two Wii-Remotes
Jonghyun Kim » Location: Roter Saal

The main concept behind this piece is changing the repetition speed. I have taken a sound file and cut it into sections. The excerpts are repeated at different playback rates. This affects the sound quality and pitch. When the repetition rate is extremely fast, the output changes dramatically. When each repetition is under 10 milliseconds in length, the original sound is no longer recognizable, and only a sine wave-like timbre remains. This process modifies the micro-structure of the sound.
Technical Summary:
This is a Wii-Remote live performance using granular synthesis. The granular-synth and algorithms was programmed in Pure Data. The performer uses Wii-Remotes in each hand and swings them in pitch and roll axis(gyroscope). The granular synthesis algorithm receives motion data from such movements of the controllers, and produces sound in realtime. The buttons on the Wii-Remote also trigger samples and changes performance mode.

Day 3 - Saturday, April/11

Concert

20:00 Cancelled: Duo Improvisation for Live-Coding and Motion Gesture-Following
Jonghyun Kim, Sungmin Park » Location: Roter Saal

Duo Improvisation for Live-Coding and Motion Gesture-Following

Linux Computer Ensemble is Seoul-based laptop performance group founded by Open Source Art Forum in Korea. They compose and perform with Linux Computers and Open Source Applications such Pure Data, SuperCollider and OpenFrameworks. Their performances include works for Live-Coding, Motion gesture-following, AudioVisual and Live-electronics.

Day 3 - Saturday, April/11

Concert

20:00 TBA
Matthias Grabenhorst, Jörn Nettingsmeier » Location: Roter Saal

Two improvisation sketches, played by Matthias and spatialized by Jörn. The plan is to do one free improvisation and one more song-oriented jazz tune, played on an electric guitar equipped with a hex pickup to allow for individual spatialization of each string, both to give the guitarist an extra layer of freedom in the treatment of melody, and to allow us to "unwrap" complex voicings by spreading them out in space.

Day 3 - Saturday, April/11

Concert

20:00 Dance I
Jaeseong You » Location: Roter Saal

The Dance Music series is now continuing with alphabetical index. More recent pieces tend to faithfully conform to IDM genre beyond simply borrowing its idioms and materials. In Dance I, the samples are initially put together in a random assemblage, and musical narratives and gestures are gradually extracted from such disorder. Some of the samples are created from SuperCollider in Linux (Ubuntu) and others are collected from both open source libraries such as freesound.org and commercial libraries.

Day 3 - Saturday, April/11

Sound Night

22:00 Vagabundo Barbudo meets Listening Lights
Andres Perez-Lopez » Location: Baron

Vagabundo Barbudo is an electro-experimental dance music project. Music is produced with free software tools, and distributed with copyleft licenses. Furthermore, "source" tracks are also distributed, in order to encourage modifications. Listening Lights is a project for automatic lighting of music. The core of the project is RTML, a graphical SuperCollider framework for Real-Time Music Information Retrieval.
In the performance, the music from Vagabundo Barbudo will be played, along with automatic reactive lighting provided by RTML.

Day 3 - Saturday, April/11

Sound Night

22:00 Hallogenerator

Site

Jakub Pisek, Roman Lauko » Location: Baron

Performance sets up the mirror to producers, DJs and pop singers, who want to enhance their vocal digitally. But the performance brings to the stage the essence of entertainment and intellectual content in musical form at the same time. It also peacefully attacks the technological literacy of the nation, the jazz police, and computer reliability.

This live performance is running on open source software (arch linux, radeon driver, pure data, arduino...).

Day 3 - Saturday, April/11

Sound Night

22:00 Superdirt² - cello & live linux electro

Site

Vincent Rateau, Daniel Fritzsche » Location: Baron

Superdirt² - fascinating electro beats mixed in with virtuous performed cello sounds which give a result of a never achieved before dance ability! With Ras Tilo at the synthesizers and Käpt'n Dirt with the cello it provides a musical experience which is situated between drum'n'bass, house, dub, dubstep and even far beyond...

The Band:
The two independent musicians knew each other through many musical projects and as flatmates, but are coming from totally different musical genres. While Ras Tilo (Vincent Rateau) got in place as a music producer and multi-instrumentalist, Käpt'n Dirt (Daniel Fritzsche) continued his classical cello studies with an open mind and ears to new musical genres.
They are mixing musical genres, looping, synthesizing, improvising and never get tired of going beyond the thinkable knowledge of music.
Their first full-length album is called "Algoriddims" - and licensed under a Creative Commons license.

Day 3 - Saturday, April/11

Sound Night

22:00 visinin
William Light » Location: Baron

Synthetic, electronic club music with an organic edge. Written and performed with Renoise, Monomes, and a variety of other software, both off-the-shelf and custom.

Day 3 - Saturday, April/11

Sound Night

22:00 Pjotr & Bass
Pjotr Lasschuit, Bass Jansson » Location: Baron

A Live performance were interaction between live-coded visuals and hybrid-trumpet are the key-elements. The software used is Pure Data, Faust and OpenFrameworks.

Installations

Day 1 - Thursday, April/9

Installation

15:30 Interactive virtual audio-visual concert simulation with TASCAR
(150 min) Giso Grimm, Joanna Luberadzka, Tobias Herzke, Volker Hohmann » Location: Installation Space

TASCAR is a toolbox for acoustic scene creation and rendering. In this demonstrator three concert stages can be interactively explored in a virtual audio-visual environment. On the first stage, a time varying physical feedback model with three moving microphones and three simulated loudspeakers is placed. This simulation without any external sounds results in a sound experience very similar to Steve Reich's "pendulum music". On the second stage a jazz band is playing. The third musical event is a contemporary piece with moving virtual sources, performed on a viola da gamba ensemble.
The interactive virtual acoustic environment is rendered in real-time and illustrates different aspects of the rendering software as well as the effect of binaural hearing. The simulation is rendered 3rd order horizontal Ambisonics. It will be reproduced in an 8-channel loudspeaker setup. This demonstration complements the TASCAR paper in the main track.

Day 2 - Friday, April/10

Installation

10:00 The Sound Of People
(135 min) David Runge » Location: Installation Space

Single-nucleotide polymorphisms (SNPs) are molecular DNA markers, that are actively being researched in general science all over the world right now. Companies like 23andMe (and others) offer sequencing parts of their customers genome (and afterwards sends that collection of data to them). To free these sets of data for use in open science, openSNP started its work on collecting, indexing and making available their users' uploads. The Sound of People was one of the first attempts of synthesizing sounds from them. It was written in the SuperCollider audio synthesis language and has been developed with the help of the Electronic Studio of TU Berlin. The software creates a unique audio experience for up to twelve speakers.

Day 2 - Friday, April/10

Installation

14:00 Cancelled: acoustic cluster (video presentation)
(135 min) Mari Ohno » Location: Installation Space

A number of pipes of different lengths suspended within a space each contain a microphone and are equipped with a freely movable speaker assembly beneath them. The distance between each speaker assembly and microphone is expressed in the "howling" acoustic response. Having divided the space with pipes, moving the speaker assemblies closer to the spaces within the pipes amplifies the otherwise insignificant howling in the space outside the pipes, producing a sound like that of a wind instrument. The pitch of these responses varies with the spatial properties of each pipe. This series of phenomena seeks to make audible the normally inaudible material of space.
(This is a video presentation of the physical installation.)

Day 3 - Saturday, April/11

Installation

11:30 3Dj (software demonstration)
(45 min) Andres Perez-Lopez » Location: Installation Space

This is a demonstration of the 3Dj SuperCollider framework for real-time sound spatialization. In the demonstration, we will explore several metaphors for sound diffusion, as algorithmic spatialization, direct sound position control through orientation sensors, or spatialization based on Music Information Retrieval. Sonic material will be both existing fixed media and live produced electroacoustic sound.

Day 3 - Saturday, April/11

Installation

14:00 C/K/P
(135 min) Adam Neal » Location: Installation Space

In C/K/P, you will see three presentations of three video 'panels,' which change position in each presentation. The sounds associated with each panel are present throughout, but are brought forward in the mix when their panel takes the center position.

The schedule is a major guideline. There is no guarantee events will take place at the announced timeslot.
