Beep Beep Boom Box is a small game developed by Patrick Rodriguez. It is a basic game, though may be better off being described as a tool.
Beep Beep Boom Box gives you control of a “tone matrix” style music toy where activating the various squares shown on the board causes various sounds to be played. It allows you to make modifications to two different channels and also has an extra percussion channel that is displayed at the bottom of the screen.
The tool even goes as far as to allowing you to modify the sounds that are played through the settings screen.
