L2Ork Tweeter is a free open source, collaborative, online (telematic), and cross-platform laptop orchestra jamming tool destined to bring current, past, and aspiring L2Orkists and the community members closer through music. Inspired by the COVID-19 social distancing, it relies only on the standard built-in desktop and laptop inputs, including keyboard and mouse/trackpad. It allows for participants to shape their instrument sound while learning basics about the audio synthesis. They can then utilize a tracker-like tool to build patterns, loops, as well as mix and modify their parameters while collaborating synchronously with up to 10 other users or performers. L2Ork Tweeter also allows for participants to chat with each other, and offers virtually unlimited additional number of guest (audience) slots who can join in to listen to the evolving music making experience. It also allows for offline composition and practice and as such may be applicable in other scenarios, e.g. live performance and DJing. Users' creations, including instruments, tracker patterns, and entire sessions can be shared and resumed at a later time. The project's name is inspired by its tracker's 64-note limit, making it a musical counterpart to the popular social media platform Twitter. This video showcases an example of a musical groove built using 5 out of 10 participant slots. For additional info visit

L2Ork Tweeter is built using Purr-Data (a.k.a. Pd-L2Ork) visual programming language that has been developed by the Linux Laptop Orchestra community. It requires a client and a server and utilizes an array of computer science concepts that were necessary to make the project possible. It also relies on the knowledge of music, music technology, and the creative technologies in music, three closely related, yet distinct areas. It leverages these elements to facilitate social interaction and community building through music. As a result, its focus is on usability and flexibility, while keeping the user interface simple and collaboration-centric.
