Cannot see the actual sequencer part

[Yukio]

Same issue. I noticed a javascript resource is not fully loaded leading to a SyntaxError and rendering the file unusable, which is why no functions on the main page work. The problem exists on all my browsers (Chrome, Firefox, Edge) on Windows 11 22631.3296. It does not exist on mobile as the mobile version of the script loads correctly (even when using mobile device mode on desktop Chrome).

edit: test.onlinesequencer.net is fully functional for the time being
