May's Monday meetup is titled: "How alive is a live-streamed Algorave?"
As corona-life well and truly passes the one year mark, let us take a moment to reflect on live-streamed Algoraves and other live-coded performances. Whilst these online events have become an integral part of cultural life, how much of the Algorave essence and vibe is still there? Are we dancing in our living rooms, pumping the music loud enough to feel the beats in our bones? Are live-coders still making the same type of music for the at home Algorave experience? Or is it anyway time to focus more on live streamed performances so as to reduce the carbon footprint of the touring artists and to level the playing field for those who can't afford or are unable to travel?
Grab a beer or tea, and come share your thoughts with us on May 10 at  8PM CEST on

<![CDATA[Algopolis - International livecoding meeting]]> DATE: Friday, 14 May 2021 | 3pm-11pm
LOCATION: osmo/za (8th floor), Slovenska 54, Ljubljana
LIVE STREAM: web live stream YT and Radio Študent

More about live coding

Live coding does not run by a common notation, and the instruments for it are hidden in the computer’s command lines. As a fairly new art form, it’s also an umbrella term that encompasses a fusion of electronic music, visuals, improvisation and live performance. A live coder composes music or visuals and creates an event in front of your very eyes. You can dance or sit or simply allow yourself to become immersed in it all.

The live coding community values shared authorship, open-source and free software, the collaboration between different approaches and a collective atmosphere. For this occasion, the meeting will take place in a hybrid form: on servers and live streams from the venue of osmo/za in the heart of Ljubljana, the new algopolis of live coding.

on-the-fly is a project to promote Live Coding practice, a performative technique focused on writing algorithms in real-time so that the one who writes is part of the algorithm. Live coding is mainly used to produce music or images but it extends beyond that. Our objectives are: supporting knowledge exchange between communities, engaging with critical reflections, promoting free and open-source tools and bringing live coding to new audiences. The project, running from 10/2020 to 09/2022 and co-funded by the Creative Europe programme, is led by Hangar Barcelona in collaboration with ZKM | Center for Art and Media Karlsruhe, Creative Coding Utrecht and Ljubljana’s Ljudmila.

Partners: Hangar Barcelona (ES), ZKM Center for Art and Media Karlsruhe (DE), Creative Coding Utrecht (NL), Ljudmila Art and Science Laboratory (SI).

<![CDATA[Rarefacció: Giulia Deval / Niklas Reppel]]> On April 30th at 6 pm, Hangar will be presenting the fourth session of Rarefacció, a cycle curated by Sergi Botella that aims to present proposals that revolve around music and the underbelly of an experimental and unconventional viewpoint. The guests for this session are Giulia Deval and the live coder Niklas Reppel.

Giulia Deval / Niklas Reppel

Date: April 30, 2021
Time: 6 pm
Price: 3 euros

Rarefacció‘s audio will be available live at

Guilia Deval

Giulia Deval is a singer and sound artist from Italy working across different formats such as live sets, creation of sound dresses, concerts of imaginary characters and collective actions for voices and magnetic tapes set in dystopian futures. Her latest work Terrapolis, released by the Italian label ANS, is a solo album in which voice and tapes play with the idea of multispecies, creating extra-human sound notes.

Terrapolis is a fictional integral equation, a speculative fabulation.
Terrapolis is n-dimensional niche space for multi species be-coming-with.
Terrapolis is open worldly, indeterminate and poly temporal.
Terrapolis is a chimera of materials, languages, histories. Terrapolis is for companion species, cum panis, with bread, at a table together – not “post human” but “com-post”*

Niklas Reppel

Niklas Reppel (*1983, Witten/Ruhr) is a live coder, composer and audio software developer currently based in Barcelona, where he found a home in the local TOPLAP community. Often he is more involved in making live coding tools (i.e. Mégra, his main performance software) than actually using them. He comes from a multifaceted musical background that features everything from jammy rock bands to contemporary chamber music ensembles, improvisation, eclecticism and Markov chains play a major role in his current live coding works.

For more information, see:, or, on Mégra:

Niklas Reppel performance is part of the European project On-the-fly funded by the Creative Europe Program.

The event will be carried out following all security measures.
Attendance will be on a first-come, first-served basis.

<![CDATA[ProxySpace: a day dedicated to live coding]]> On May 5th, MUTEK ES and On-the-Fly, a European project led by Hangar, co-organize ProxySpace, a day dedicated to live coding workshops and performances. Live coding is a performative technique focused on writing algorithms in real time that is mainly used to produce music or images, but also extends to other areas.

During the day, livecoder Shelly Knotts will give a hands-on workshop that will allow attendees to learn the basics of creating a live coding session, producing soundscapes, beats and patterns in SuperCollider — an open source programming language used to create music —, reactive audio/music installations, interactive systems, live coding and much more.

At the end of the afternoon, there will be six sound and visual performances that explore live coding from different points of view.

The performers who will perform as part of this co-production are:

Shelly Knotts, one of the artists awarded a grant from the On-the-Fly open call. Shelly Knotts is an improviser whose performances collaborate with computers and humans. Her interest in code, data and networks has led her down strange and diverse musical paths, from electroacoustic composition, to jazz and noise music, to Algorave. She experiments with generative and AI techniques and algorithms to make music. She has performed at numerous Algoraves and other live coding events around the world, solo and with collaborative projects such as ALGOBABEZ.

Iván Paz has a background in physics, music and computer science. Ivan’s work is framed in critical approaches to technology focused on from-scratch construction as a technique of exploration. Since 2010, he is part of the live coding community and has presented workshops, conferences and concerts in America and Europe. He is currently working with machine learning techniques while maintaining the real-time feedback characteristic of live coding.

Julia Mújica is a Mexican scientist dedicated to the artistic exploration of the complex processes of nature. With an interdisciplinary background spanning biology and computational physics, she is deeply interested in understanding how collectives make decisions that result in behavioral synchrony. Recently, her curiosity has extended into the artistic sphere, where the process of creation magnifies and prioritizes different aspects of the same phenomenon. Her work includes animated particle design in processing language, noise design from random walk algorithms for modular synthesizers, and collaborations with artist Lina Bautista on rhythm and collective patterns with interactive robots.

Roger Pibernat is an illustrator and musician who constantly explores other artistic disciplines and fields of knowledge. He started working with SuperCollider around 2006. He has been part of the Barcelona Laptop Orchestra and co-founded the Wú collective with which he has developed electroacoustic instruments, audiovisual performances, software and interactive installations. He is currently an active member of the Barcelona live coding community.

Glen Fraser (aka totalgee) is a Canadian software developer who has worked in graphics, sound, interactive and immersive technology for over a quarter of a century. Most of his professional life has been spent creating software tools for artists and collaborating directly with them. His initiation into live coding was in 2013, when he also belonged to the Barcelona Laptop Orchestra and the Wú Collective. Inspired by the TidalCycles pattern language, and following the (cheerfully irrational) live-coder tradition of reinventing the wheel, Glen develops and uses “Bacalao”, his personal collection of live-coder tools for SuperCollider.

Iris Saladino is a sound-oriented creative coder based in Buenos Aires. Member of CLiC (Live Coders Collective). She works live coding music (mainly, but not only) with TidalCycles and visuals with Hydra. She has performed at: UNSaM, UBA, Rolf Art Gallery, Museo Sívori, Museo Moderno, Centro Cultural San Martín, Centro Cultural Recoleta, Centro Cultural Ciencia, Planetario Buenos Aires, Planetario Bogotá, among others. Festivals: Amplify Nano Mutek 2019, BA; Festival Domo Lleno, CO; Festival de Música en Red, DE; Festival No Bounds, UK; Piksel, NO; OverKill, NL; SpamArts, BA. Irís will perform live from Buenos Aires.

Ivan Paz and Julia Mújica’s performance integrates symbolic machine learning for sound synthesis and systems with collective behavior for the visuals.

Shelly Knotts and Glen Fraser will combine broken SuperCollider synths and automatic drum machines with particle and shader effects to create fluid, responsive spaces.

Roger Pibernat and Iris Saladino will work together integrating programming languages such as Hydra, Tidal and SuperCollider to produce sound and visual narratives.

The session will be face-to-face and streamed.

The Algorave will follow its community guidelines.

<![CDATA[on-the-fly cantina]]> The on-the-fly research group invites everybody interested in live coding to participate in a series of monthly casual video chats. Each session will be hosted by one or more members of the community and will be based around a different question. Rather than focusing on tools and specific programming languages,  these meetups will provide a space to discuss aesthetics, meta levels and how we relate to live coding - both as artists and as audience.
The first meeting will be on April 12th with the theme “Now that we have gathered - what should we discuss?”. This will be an opportunity for everybody to meet and share interests, concerns and areas of interest for future discussion. On May 10th we have scheduled: “How alive is a livestreamed Algorave?” -  a topic very relevant to our current situation and one that considers the practice of televised live coding in general.
So come join us on the 2nd Monday of each month starting this April and share your ideas and questions on everything you always wanted to know about live coding (but were afraid to ask).
At 8PM CEST follow this link :
We follow the code of conduct of the live coding community that can be found at the end of this page.
We are looking forward to chatting with all of you soon!

<![CDATA[Algorave]]> On March 26th at 6 pm, Hangar hosts an Algorave, a visual and sound algorithmic festive event co-organized by Sónar Festival and On-the-Fly — a European project led by Hangar — within the framework of VIU festival.

The Algorave, a term originally coined in 2012 by Alex McLean and Nick Collins, is generally executed through live coding, writing and modifying algorithms in real time with the computer as the physical interface. Its practice has spread to include, for example, patch modifications or interactions between electronic devices and code. Influenced by the hacker philosophy, in particular by the “open source” concept, the audience’s attention is divided between the music and the code that is displayed and that allows the programming process to be observed. This is why, in essence, an Algorave has a strong improvisational component, is alive and likes to take risks and explore limits.

The session will be on site and streamed.

The performers that will play in the framework of this co-production are:

Alexandra Cárdenas

Alexandra Cardenas’ work focuses on the algorithmic behavior of music and the exploration of musicality within code. She is a core member of the international live coding and algorave community and performs worldwide using the live coding platforms SuperCollider and TidalCycles. Alexandra studied composition at Universidad de Los Andes in Bogotá, Colombia, and later completed a Sound Studies Master’s Degree at Universität der Künste, Berlin, where she has lived since 2013.

Alicia Champlin

Is an American intermedia artist and researcher from Maine, based in Barcelona since 2017. She works primarily with generative systems and sound, using installation and performance to explore aspects of agency and embodiment, with past exhibitions in Austria, Norway, the United States and Spain. Frequencies, resonance and feedback – especially biofeedback – are favorite tools. Champlin also plays the bow chime, sometimes with EEG augmentation. Relatively new to live coding, she is experimenting with the intention of playing in the space between indeterminacy and predictability.


Hailing from the valley of Caracas, Venezuela, Chigüire is the nom de guerre of Jesús Plasencia, a multimedia artist interested in the dialogue between humans and machines. Although they have spent much time using computers as a crude tool to earn money to survive, he found a calling in live coding and computer art in general. Despite being one of the newest participants of TOPLAP Barcelona, they quickly found a home there, and a place to grow in the art of making computers draw and sing, with the hopes of someday getting them to tell us their secrets.


QBRNTHSS (pronounced “quebrantahuesos”, meaning “bearded vulture” in Spanish) is the alias that Ramon Casamajó, musician and computer scientist, uses for his solo works focused on electronics and live coding. As QBRNTHSS he released a split LP (Harry Dean Stanton, Call It Anything Records 2019), and is actively involved in the TOPLAP Barcelona collective. He has participated in online events hosted by the international TOPLAP community. He is part of Turing Tarpit, a duet with whom he has released several works and played regularly in Barcelona’s experimental underground circuit. He also runs the micro record label Call It Anything Records.


Linalab is a multiple singularity. It’s a whole and a unity, a solitary sound, and a note. A frequency that remains in time to become more complex, to become entangled, to become noise; melody, song and then silence. Linalab does not only exist on stage. Besides playing at numerous events and festivals, she also understands music as an ongoing process of investigation. She is a producer for the Synth Vicious record label; plays an active role with TOPLAP Barcelona and creates electronic sound devices with Familiar DIY.

Toni J

Toni Jaume is a digital artist, developer and creative programmer interested in generative processes, with a special interest in computer graphics. His research processes about metalanguages and new paradigms are the common thread that is reflected in his interactive pieces and installations that often focus on the language of videogames as a way to consolidate an understandable discourse between the observer and the concept. Through live coding, he explores new ways to elevate creativity to an exponent of constant creation in which improvisation derives generative graphics in a constantly changing world that draws on the concepts of fractality.


Also known as Citlali Hernandez, her work investigates the implications of the body and the use of new technologies in the arts. She has presented some of her projects in various spaces and festivals such as: CCEMx (Cd.Mx), CMMAS (Morelia), GAM Cultural Center (Santiago de Chile), L’Estruch Cultural Center (Sabadell), SALA OFF (Valencia), JustMAD Contemporary Art Fair 15 and 17 (Madrid), ECOSS Festivals 18 and 19 (Barcelona).

She is currently involved in university teaching, is a resident artist at Hangar, the open center for research and artistic production, and holds a doctorate from the University of Vic and BAU, University Design Center of Barcelona. She is also an active member of the Live Coding collective TOPLAP_Barcelona.

The Algorave will follow its community-sourced guidelines.

<![CDATA[on-the-fly research group]]> Live coding is the creation of real-time compositions by writing source code. As can be seen by the performance setup, the live coding practice highlights the role of the composer-programmer in today's world. 
Live coding activities have many layers and composer-programmers  have spent extensive hours designing, understanding, or extending numerous languages or libraries before performing. In addition, reflecting on live coding nature and possibilities contextualizes and restricts the possible paths to follow. This is an essential process as the possibilities would otherwise be infinte. 
For these reasons, the "on-the-fly" project has both a space for performances and  a space for research. In the research space we can discuss, explore, identify, reflect on and imagine creative directions in the live coding practice.
The members of the group are Anne  Veinberg (Creative Coding Utrecht), Patrick Borgeat (Karlsruhe University of Music, IMWI), Luka Frelih, Dare Pejić (Ljudmila Laboratory) and Iván Paz (Hangar).
