Press the keys 1, 2, 3, and 4 to use sounds, press the play button to record. Press space to play your creation. -NOTE- Playing is still in testing, so it won't work very well. If it does end up working, it will play in slo-mo, because for some reason a block saying [wait (0.01) secs] waits for a LOT longer than that... BUT! But butbutbutbutbut but of all buts: if you have all the sounds on a different second, they will play properly! Which means: this could work if they fix these variables.
