In Beatroulette, a number of music producers get together, in order to creatively work on a number of tracks in a round based minigame.
The way this works is by everyone choosing BPM and Key for their first round entry. After creating the first stem (Drums/Sample) they upload their file.
Silo 1
Silo 2
Silo 3
Silo 4
Silo 5
Silo 6
Each player is moved to the next Silo. There, players are notified about this Silo's BPM and Key, as well as the next stem they will have to create. To enable this, players automatically get the assigned download links for stems in their current Silo.
What stem has to be created in which round be configured by the admin when creating the game.
Silo 1
Silo 2
Silo 3
Silo 4
Silo 5
Silo 6
Each player is rotated again. This keeps going until all rounds are played. At the end, there is just as many unique songs as there are players in the game - with everyone having participated in every song (at least if you have played as many rounds as there are players).
