Open Collidoscope

Collidoscope is an interactive, collaborative sound installation and musical instrument (granular synthesizer) that allows participants to seamlessly record, manipulate, explore and perform real-world sounds.
It is designed for both amateurs and professional musicians.

Collidoscope was created by Ben Bengler and Fiore Martin and it builds on on the research conducted at the Center for Digital Music at Queen Mary University of London in real-time sound processing and synthesis, hardware design, physical computing, UI design, designing for interaction, accessibility and collaboration.

The granular synthesis engine is based on Ross Bencina's paper Implementing Real-Time Granular Synthesis, on the TGrains Unit Generator of the SuperCollider language and on the Cross-modal DAW Prototype developed in the EPSRC funded project Design Patterns for Inclusive Collaboration (DePIC)

Collidoscope was supported by the EPCRC Centre for Digital Music (C4DM) Platform Grant (EP/K009559/1), the EPSRC Design Patterns for Inclusive Collaboration (DePIC) grant (EP/J017205/1), and b00t Consultants Ltd (b00t).
