QuaverSeries consists of a domain-specific language and a single-page web application for collaborative live coding in music performances. Its domain-specific language borrows principles from both programming and digital interface design in its syntax rules, and hence adopts the paradigm of functional programming. The collaborative environment features the concept of 'virtual rooms', in which performers can collaborate from different locations, and the audience can watch the collaboration at the same time. Not only is the code synchronised among all the performers and online audience connected to the server, but the code executing command is also broadcast. This communication strategy, achieved by the integration of the language design and the environment design, provides a new form of interaction for web-based live coding performances.

RaveForce is a programming framework designed for a computational music generation method that involves audio sample level evaluation in symbolic music representation generation. It comprises a Python module and a SuperCollider quark. When connected with deep learning frameworks in Python, RaveForce can send the symbolic music representation generated by the neural network as Open Sound Control messages to the SuperCollider for non-realtime synthesis. SuperCollider can convert the symbolic representation into an audio file which will be sent back to the Python as the input of the neural network. With this iterative training, the neural network can be improved with deep reinforcement learning algorithms, taking the quantitative evaluation of the audio file as the reward. In this paper, we find that the proposed method can be used to search new synthesis parameters for a specific timbre of an electronic music note or loop.

In this installation we explore how six self-playing guitars can entrain to each other. When they are left alone they will revert to playing a common pulse. As soon as they sense people in their surroundings they will start entraining to other pulses. The result is a fascinating exploration of a basic physical and cognitive concept, and the musically interesting patterns that emerge on the border between order and chaos.
