A web-based audio-visual programming system, Tweakable prompts users to “make interactive and generative music, sound and visual art” by making them choose from a wide range of components to design their own algorithmic systems while also setting up controls that allow them to adjust how the algorithm works in real-time, hence the name “Tweakable.” According to the Wayback Machine, Tweakable.org was first active on June 6, 2002, and then was inactive from 2003 till 2020; finally, the website we currently have was a version launched on December 17, 2020 (“Wayback”).
There are 3 big components in Tweakable: Data Input/Flow, Sequencing, and Audio, with an additional option to create custom modules as well. Data Input/Flow includes control inputs like sliders and MIDI and controls how information flows in the platform. Sequencing generates and transforms musical patterns using grids, scripts, and mathematical functions, while Audio converts sequences into sound through instruments, oscillators, and automated effects (Woodward). When the user wants to create a new project, they will first choose from a pre-built library made of sequences, audio, video, effects, etc., and they will then connect those components together to create an algorithmic system. Finally, after the system has been made, they will also need to build a user interface so that their algorithm can be tweaked (“Tweakable”).
With its main goal is lowering the entry barrier for programming music or visual art for all users, Tweakable invites users with no background knowledge to not only easily create their own works but also share their projects “without worrying about missing dependencies” since it’s web-based. By being a web where users can tweak and experiment with parameters in live time, Tweakable was one of the earliest pioneering live coding platforms at the time of its creation; and not only does it encompass live coding’s key characteristic of allowing users to write and modify code in real-time to create music and visuals, it also made the algorithmic generation of art more accessible and intuitive with its visual component-based approach, thus opening up the platform to anyone ranging from a total novice to an expert (Woodward).
Finally, here’s a video of me playing around with Tweakable, and the slides are here 🙂
