This section gives a complete listing of the code used in this chapter. You can refer to it if your code is not working to see what changes need to be made. Some of the code blocks have been moved around within the program to keep similar parts of the program together. This can make things easier to read, but it is completely optional. The following is the complete code used in the chapter:
pace = 0.8
define :play_notes do |notes, durations|
together = notes.zip(durations)
together.each do |note, duration|
if one_in(2)
speaker = -1
else
speaker = 1
end
play note, release: pace * duration, pan: speaker
sleep pace * duration
end
end
define :drum do
sample :drum_tom_lo_hard, attack: 0, sustain: 0, release: 0.2
end
define :play_beat do |beat|
beat.each do |pause|
drum
sleep pace * pause
end
end
rhythm = [1, 1, 1, 0.75, 0.25, 1, 0.75, 0.25, 2]
