For our project, we decided upon a MIDI controller because it sounded (ha, get it?) cool.
We wanted to be able to build something that would take MIDI files, convert them into 8 bit music, and play them out loud. We took inspiration from the music which we heard in older video game consoles and arcade cabinets. The songs we would choose would be from different games, TV shows, and movies that we all enjoy. On that note (more puns), this allowed for each member of the team to have some input in the direction we took with the project and get something personally enjoyable with the finished product.
