BeepBox

BeepBox is a Flash-based tool for sketching and sharing chiptune melodies.

All song data is packaged into the URL text at the top of your browser. As you make changes to the song, the text after the "#" in the URL is updated to reflect your changes. When you are satisfied with your song, copy and paste the URL to save and share your song.

Instructions

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 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 in the Flash rectangle above), you can use these keyboard shortcuts:

Spacebar: Pause or Resume
Z: Undo
Y or Shift Z: Redo
C: Copy the current pattern
V: Paste the current pattern
[ ]: Move the playhead backward and forward
Arrow Keys: Change which bar is selected
1-8: Reassign a pattern to the currently selected bar

In the pattern editor, you can click above or below an existing note to enable a rapid arpeggio/trill effect. You can also drag horizontally on a note to adjust its duration.

ADVANCED: Drag vertically from an existing note to bend its pitch, or drag vertically 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!

You can download an offline version of BeepBox (right click and select "Save As...") to use when you don't have access to the internet. The features are otherwise the same. You can open BeepBoxOffline.swf in a browser tab to run it, or you can install a Flash Projector to run swf files without a browser.

You can also download and use the source code under the MIT license. You can use the synth code to play BeepBox songs in your own Flash projects.
