press "r" to generate a random 41-digit number that builds 1 bar of treble and bass melody, and press space to play it. This means that if you like a seed, you can copy & paste it into the program to play it again, or put it in the comments so i can add a customised letter for you. Keep in mind that because the music is generated directly from the seed, melodies will be a bit jumpy. This machine only knows basic music theory. Press the up and down arrows to toggle variables. Next update I may make it so that the treble melody plays a harmonic note when it hits the beat off the bass
