JummBox is an online sequencer based off of John Nesky's BeepBox
created by Jummbus. It can be found here: https://jummb.us/

Restrictions on submit



• Your submitted file has to be a .txt including the jummbox-url.
(for avoiding any eventual confusion, please help verifying this, and correct if needed: the base64 code in this jummbox-url is actually the compressed song, not a kind of file id hosted somewhere online, like pastebin or youtube does )
• Variants such as Modded Beepbox, Todbox etc. (or the original BeepBox) are allowed!

Playback (for voting)



You can simply open the url
There is also an offline player(?) More information needed pls KEFFIE!!!

HELLO kleeder!!! yes, there is an offline player here: https://jummb.us/jummbox_offline.html (you just save the webpage and it will work the same)

Render to MP3



MP3s, as well as other formats, can be quickly produced in the file menu. Options to loop x amount of times before going to the outro are included!
