Click the rectangles to add notes, (should play a sound if you have audio on) and then click the play button to play the music. If you want to make it longer than 12 notes, though, click the small save button to save the page, and then click the next button at the bottom to create a new page. At the top of the GUI on the left, there is an indicator showing how many pages you have. Always be careful to save the page you are currently on before switching back or forward and losing your notes. To play the whole song, go back to the first page and click play, and it'll automatically go forward through the pages to play until it gets to the end. If you put your mouse at the very top of the screen, you will see some sliders for tempo, (not normal tempo; it is the delay between notes in seconds) offsetTune, (it makes all notes higher or lower) and drumType. (each number represents a different drum [drums are the very top note of the page]) To clear the page, click the X button, and remember to click save right after to make it actually count. The button to the right of the play button updates the page indicator if you have deleted some pages. (so if you've saved an empty page, it to counts) The wide button below it will save the entire track into a code that you can copy and paste. (when saving the whole track, you have to start at the FIRST page, and when saving in general, don't put your mouse on the grid or it will consider your mouse as a note) To load a track click the down arrow button and then paste the savecode from saving. (same as saving, keep your mouse off the grid)
There is actually a first of this but it is really bad.
