I had a decent little beat cranked out, about 12-15 whitened squares. Gotta get a screen recorder or something. *edit* Or, number codes...
50312,50308,770,99074,99460,1160,25360,25104,1032,99340,98834,274,51340,102540,51474,530 there. where's my record deal?
copy them and then paste them on the matrix and it will fill in the corresponding squares to give you the beat.
