The JamDex, an index of user-created jams, developed by Jam(es) and Dex(ter). Made using tone.js with React and a Python back-end serving a PostgreSQL database with Flask over 7 days. We created a user interface in React, based on a physical monosynth and drum-machine, which allows users to create short looped 'jams' with tone.js and save them to 'tapes' which are stored on the SQL database.
