We all spent this weekend working on different aspects of the project and had time to reconvene during class and combine our code into a final product. This code combines my shapes that get called by midi notes played on a keyboard,

This code does everything we want it to do, now it’s just time to refine our final project into something we’re excited to present. Currently, the visualizer looks like this:
The color splashes get added (different shapes and colors depending on the note) when the keyboard is played, and the gradient in the background transitions between blue and red. These next few days we are going to be putting the finishing touches on the project by creating a “clear” function, changing the way the timer works so it hopefully is less buggy, and trying to get the color splashes to animate by rotating. We are meeting tomorrow to hopefully get these finishing touches worked out!
