##############################################
## Example 1 - play a note
play 60


##############################################
## Example 2 - play 4 random notes
4.times do
  play rrand_i(60, 90)
  sleep 0.5
end


##############################################
## Example 3 - play a major chord
play chord(60, :M)


##############################################
## Example 4 - play an arpeggio
loop do
  play chord(60, :M7).tick
  sleep 0.5
end


##############################################
## Example 5 - play a chord with an arpeggio
loop do
  play chord(60, :M7), release: 3
  16.times do
    play chord(60, :M7).choose
    sleep 0.25
  end
end


##############################################
## Example 6 - play a shifting chord with an arpeggio
start_notes = ring(60, 62, 63, 62)
loop do
  my_chord = chord(start_notes.tick, :M7)
  play my_chord, release: 2
  16.times do
    play my_chord.choose
    sleep 0.125
  end
end


##############################################
## Example 7 - play a sample
sample :drum_bass_hard


##############################################
## Example 8 - play a simple drum beat
loop do
  sample :bd_haus
  sleep 0.5
end


##############################################
## Example 9 - alternate kick and snare
loop do
  if tick.even?
    sample :bd_haus
  else
    sample :sn_dolf
  end
  sleep 0.5
end


##############################################
## Example 10 - combine kick, snare and hi-hat
loop do
  sample :drum_cymbal_closed
  if tick.even?
    sample :bd_haus
  else
    sample :sn_dolf
  end
  sleep 0.25
  sample :drum_cymbal_closed
  sleep 0.25
end


##############################################
## Example 11 - play a drum loop once
sample :loop_amen


##############################################
## Example 12 - play a drum loop as a loop
loop do
  sample :loop_amen
  sleep sample_duration(:loop_amen)
end


##############################################
## Example 13 - try to combine melody, harmony, rhythm (doesn't work)
loop do
  start_note = ring(60, 62, 63, 62).tick
  my_chord = chord(start_note, :M7)
  play my_chord, release: 2
  16.times do
    play my_chord.choose, release: 0.25, amp: [0.75, 0.5, 0.25].choose
    sleep 0.125
  end
end

loop do
  sample :loop_amen
  sleep sample_duration(:loop_amen)
end


##############################################
## Example 14 - a fix for Example 13, using threads (drums out of sync)
in_thread do
  loop do
    start_note = ring(60, 62, 63, 62).tick
    my_chord = chord(start_note, :M7)
    play my_chord, release: 2
    16.times do
      play my_chord.choose, release: 0.25, amp: [0.75, 0.5, 0.25].choose
      sleep 0.125
    end
  end
end

loop do
  sample :loop_amen
  sleep sample_duration(:loop_amen)
end


##############################################
## Example 15 - a fix for Example 14, drums now in sync
in_thread do
  loop do
    start_note = ring(60, 62, 63, 62).tick
    my_chord = chord(start_note, :M7)
    play my_chord, release: 2
    16.times do
      play my_chord.choose, release: 0.25, amp: [0.75, 0.5, 0.25].choose
      sleep 0.125
    end
  end
end

loop do
  sample :loop_amen, beat_stretch: 2
  sleep 2
end


##############################################
## Example 16 - a better way to thread
live_loop :beeps do
  start_note = ring(60, 62, 63, 62).tick
  my_chord = chord(start_note, :M7)
  play my_chord, release: 2
  16.times do
    play my_chord.choose, release: 0.25, amp: [0.75, 0.5, 0.25].choose
    sleep 0.125
  end
end

live_loop :drums do
  sample :loop_amen, beat_stretch: 2
  sleep 2
end


##############################################
## Example 17 - use a different synth
use_synth :saw
loop do
  play scale(60, :major).choose
  sleep 0.25
end


##############################################
## Example 18 - a simple pattern to demo effects
play 50
sleep 0.5
sample :elec_plip
sleep 0.5
play 62


##############################################
## Example 19 - adding reverb
with_fx :reverb do
  play 50
  sleep 0.5
  sample :elec_plip
  sleep 0.5
  play 62
end


##############################################
## Example 20 - adding echo
with_fx :echo do
  play 50
  sleep 0.5
  sample :elec_plip
  sleep 0.5
  play 62
end


##############################################
## Example 21 - adding reverb and echo together
with_fx :echo do
  with_fx :reverb do
    play 50
    sleep 0.5
    sample :elec_plip
    sleep 0.5
    play 62
  end
end

CHORD CONTROL

This part provides two rings called "chord_high" and "chord_low".

They always contain the "permitted" notes in order that everything will be in tune.

You can use them in other live loops to select notes.

chord_1 = chord :c4, :maj9, num_octaves: 2
chord_2 = chord :es4, :maj9, num_octaves: 2
chord_3 = chord :b3, :maj9, num_octaves: 2
chord_4 = chord :d4, :maj9, num_octaves: 2

chord_low_1 = chord :c2, :maj9
chord_low_2 = chord :es2, :maj9
chord_low_3 = chord :b1, :maj9
chord_low_4 = chord :d2, :maj9

chord_high = chord_1
chord_low = chord_low_1

live_loop :chord_selector, delay: -0.5 do
chord_high = (knit(chord_1, 2, chord_2, 2, chord_3, 4,chord_4, 4)).tick
chord_low = (knit(chord_low_1, 2, chord_low_2, 2, chord_low_3, 4, chord_low_4, 4)).look
sleep 8
end

SPHERES

define :chord_player do |the_chord|
use_synth :blade
the_chord.each do |note|
play note, attack: rand(4), release: rand(6..8), cutoff: rand(50..85), vibrato_rate: rand(0.01..2), amp: 0.55
end
end

live_loop :chord_loop do
