Everything you hear in this project is made up of either Sine, Square, Sawtooth, or Triangle soundwaves mixed together! Play a note on the keyboard to try it out, mess around with the sliders, experiment!
If you want to know the full capabilities of Instrumentality and how to use them then please refer to the user manual: https://scratch.mit.edu/projects/1368385363/ Credits: Audacity, I generated the soundwaves on this program. Backdrop Rendered by Mandelbulb 3D.
