INSTRUCTIONS: Use Space Key to set the Metronome to what you want, any number from 0-999 will work. It sets it to 60 automatically. WHAT IS A METRONOME? The number of beats per second is 60 divided by the metronome, so for example if the Metronome is 60 it will be a beat every second and if it's 120 it will be every half second and so on. Made completely by me.
