Hello! Karasuro here. I just downloaded OpenComputers recently and have been testing things out. Here is my first program I've written in OC and it needs lots of improvement and optimization but at least it works. Note: You may need a high-end computer for this to work. I made it using Teir 3 everything. (Creative Mode) Also you will need to hook up a note block.
Now checks the resolution of the system before changing it's local resolution. Returns to the previous resolution upon exit.
To-Do:
Add variable tempo.
Switch to Computer.beep() for extra pitch support.
Add variable scale
