Sonic Pi Chiptune Tutorial

#Chiptune tutorial by JorshTheHacker for Sonic Pi.
use_bpm 120 #125 or 130 work better for some songs but 120 is a good number to start with.
use_random_seed 86 #You may want to change this.

melody = (ring :c4, :d4, :e4, :f4, :g4, :c5, :b5, :d5, :a5) #melody. This is the sequence of notes for the square (pulse) synth(s).

cmelody = (ring :e4, :d4, :c4, :g4, :f4, :e4, :b4, :a4) #counter-melody. This is for the saw synth.

bass = (ring :c3, :e3, :g3) #Bass notes. This ring is for the bass synth. Bass sounds should be constant and simple, so keep this between 3 and 5 notes.

bass_synth = choose([:tri, :chipbass]) #You can change the seed (above) to modify this.)

#timing tools:
x = 0
y = 0
z = 0

#Add onto and modify this, and you should be good to go!
