Instructions

You can add or remove notes by clicking on the gray rows at the top. UserBox automatically plays the notes out loud for you. Try it!

Notes go into patterns, and you can edit one pattern at a time. Those numbered boxes at the bottom of the editor are the different patterns you can edit. Click the boxes to move to a different part of the song, or click the arrows on the currently selected box to swap which pattern is played during that part of the song.

UserBox can play several rows of patterns simultaneously, and each row has its own set of patterns. Most rows can play melodies or harmonies, but the bottom row is for drums.

All song data is contained in the URL at the top of your browser. When you make changes to the song, the URL is updated to reflect your changes. When you are satisfied with your song, just copy and paste the URL to save and share your song!

Keybinds have been moved to the User Manual! Scroll up to find that!
