Smoothly fading samples and synths

Looking at @josephwilk’s post (Making a ‘drop’) this even becomes much simpler with set_mixer_control!. Sam has taken care of that already.

But as the saying goes: detours increase the local knowledge.

# beats and bars: 
# 1 bar = 4 beats = 16 * 0.25 beats
# if you count all the sleeps, the tune is 16 bars or 64 beats long
use_bpm 120
set_mixer_control! amp: 1, amp_slide: 8

# one loop = one bar
# let the drums play for 16 bars, 4 bars fade in
in_thread do
  16.times do
    sample :loop_amen, beat_stretch: 4
    sleep 4
  end
end

# after the 4-bar-fade start the the bassline
sleep 16

# bassline is 2 bars long (8 beats)
# let it play along the drums which will last for
# 12 bars from here on ...
in_thread do
  with_synth :fm do
    with_synth_defaults release: 0.5, cutoff: 60, depth: 2, amp: 1.5 do
      6.times do
      play :c2
      sleep 0.5
      play :c2
      sleep 4
      play :g2
      sleep 3
      play :bb2
      sleep 0.5
    end
   end
  end
end

# start the keyboard after the bass phrase has played 2 times
# = 16 beats
sleep 16

in_thread do
  with_fx :reverb, room: 0.75, mix: 0.5 do
    with_synth :dsaw do
      with_synth_defaults cutoff: 80, amp: 1.5 do
        4.times do
          play (chord :c4, :minor7), release: 0.25
          sleep 1.5
          play (chord :c4, :minor7), release: 1.25
          sleep 1.5
          play (chord :d4, :minor7), release: 0.25
          sleep 3.5
          play (chord :d4, :minor7), release: 0.25
          sleep 1.5

      end
    end

# remaining beats/beats for the track is 32 beats / 8 bars
# let 4 bars play and then fade out for 4 bars
