The music slowly changes over time and will not stop on its own. This is a new idea combining the oscillator setup with byte beat music to allow for enough space to write graphics code!

Thanks to @donbright who showed me where i could save 5 chars
u/iverjo

Very impressive :D
u/donbright

this is unbelievable. (ps thx but i stole the idea from others here)

(ok technically they gave it to me prob @cantelope / @manga)
u/Woodmouth

This is the strangest piano i've ever played, but good job!
u/Woodmouth

Also, i found a way to stop it, just press shift. (or any other key with a value too high or low to hear (At least i think that's what happens))

Check the old comments for some simple tunes to play. You'll need to click on the blank canvas for keyboard focus. Hit Space, Shift or Escape for "silence".

Excellent! #audio #music For anyone who wants the sound to stop, just scroll down to the next dweet then hit Reload.

It sounds good enough with 200 instead of 99 but +1 over
