BeepBox is an online tool for sketching and sharing chiptune melodies.
All song data is packaged into 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!
You can add or remove notes by clicking on the gray rows at the top. BeepBox 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 other 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.
There are four rows of patterns that BeepBox can play simultaneously, and each row has its own set of patterns. The first three rows can play melodies and the bottom row is for drums.
The purple loop underneath the numbered boxes controls which part of the song is currently repeating. Move the loop to listen to a different part of the song, or drag the ends to expand the loop to include the whole song.
When BeepBox has focus (click on its interface above), you can use these keyboard shortcuts:
In the pattern editor, you can click and drag horizontally on a note to adjust its duration. You can also click above or below an existing note to enable a rapid arpeggio/trill effect, oscillating between two or more simultaneous notes.
ADVANCED: Drag vertically from an existing note to bend its pitch, or drag vertically from above or below the note to adjust its volume.
BeepBox has many more features. Try playing with the buttons and menus on the right side to find out what it can do!
