In order to make your music you will need to know how this all works. First of all, the wire only carries a pulse in the top left and top right directions. This is due to how the plug-in works and I don't plan on changing it. Now, in order to send a pulse through the wire, you must place and activate a switch next to it. After that, just place some music tiles adjacent to a wire and send a pulse through to activate the music tiles. If wires and switches aren't your thing, you can always tap on the music tiles to get them to produce sound.
