A few years ago, when I was first learning about browser APIs and JavaScript, I build an audio synthesizer web tool using the Web Audio API called AquaSonic. One of the cool features of this synth was a touchpad interface that could bend pitch and control frequency cutoff based on the X-Y position of the touch.

I decided it would be an interesting exercise to revist this interface with an OOP+TypeScript approach.

I went through several iterations of this interface in the short span I worked on it, each time trying to implement principles of Clean Coding to separate concerns, reduce redundancies, and provide room for expansion where possible. I like the class that came from it, and I'm not sure if I will ever use it but I think it could have some very cool applications for survey responses on a 2-dimensional matrix, or compound control of two settings at once, or even touch control interfaces like AquaSonic if I'm feeling bored in the future!
