Take a seat
Each player presses a button on their own controller to join and takes a spot on the screen. Pick a layout that fits your players.
Playing with several keyboards and mice? Press End once everything is in place to give each window its own cursor.
Launch and connect
Press Launch: Nucleus opens one copy of BlasterBeat per player and lays the windows out on your screen. Then link them in game, usually one player hosts a LAN or online session and the others join it. The handler notes say how.

Handler notes

IMPORTANT: start the main game once before playing in split screen. Highly recommended to use keyboard/mouse while in the menus as they are weird with controllers.

FOR WORKSHOP SONGS: Download the ones you want then go into the folder steamapps > workshop > content > 1575680 , in this folder copy all the songs you want then go into your Nucleus Co-op folder > handlers > BlasterBeat and paste the folders you copied in there. To use them create a custom tracks match and when going to add a song check the SELF CREATED option and they will appear (name only, no cover), this is buggy but it works.
