How to Play

• Download the project by clicking the button above, open Terminal, and run "chuck bart2.ck"
• Click or drag dots on the screen (dots will light up when you hover over them) to draw subway lines
• Click on an intersection of 2 different lines to produce an interchange!
• Press number keys 1-7 to switch between colors (1 = red, 2 = green, 3 = yellow, 4 = magenta, 5 = blue, 6 = pink, 7 = silver)
• Press enter to pause/resume the map (similar to Mini Metro)
• Press delete/backspace to remove a line entirely. The line removed depends on the color selected (controlled by keys 1-7)
• Press space to toggle between dark and light modes
• Press or hold up/down arrow keys to speed up/slow down the entire system, respectively
• Press left/right arrow keys to lower/raise the key signature of the system, respectively
• Different subway lines produce different sounds. Find out what they are! Make combinations! Have fun!!

Final Reflection

This has been one of my favorite coding projects ever. I’m so glad I got the chance to bring what I was fantasizing about a month ago into reality. I made a musical Mini Metro! Ever since making my first audio visualizer, I was inspired to tackle the task of making a project that directly relates to my interests (and continues my CCRMA train series). It wasn’t easy, but after countless hours of designing, redesigning, and debugging, I have created what I have here. It’s not perfect, but certainly is a step up from all my previous coding projects, especially because this is one of the first times where I developed a working program from the ground up instead of editing starter code! Working on this has been one of the first times where I truly felt like a designer while coding, and thus I am grateful for this experience. Below is a high-level class diagram for my system design:

Special Thanks

I would like to start by thanking Kunwoo Kim and Andrew Zhu Aday for their immense help throughout this project, without whom I wouldn’t be able to create what I have now. Thank you so much to you both for guiding me step by step towards building a project from scratch (instead of retexturing Drum Machine). I would also like to thank Kiran Bhat and Samantha Liu for their invaluable work last spring when we worked on A to JFK, which this sequencer takes heavy inspiration from. Finally, I would like to thank Tae Kyu Kim for their words of encouragement and suggestions on how I could improve my sequencer. Appreciate you all!
