Controlling bar patterns

Performances, Streams & Live Coding

Here is some code I wrote during a livestream, for patterns of bars.

Parameters:

use_bpm 100

#Some drum patterns
pattern1 = (bools 1,0,0,0)
pattern2 = (bools 0,0,1,0)
pattern3 = (bools 1,1,1,1,0,1,1,1)
pattern4 = (bools 0,0,0,0,1,0,0,0)

bars = (bools 1,1,0,0,1,1,1,0)  #Pattern of bars on/off

beats_per_bar = 8  #Number of beats in a bar

One-shot version:

#One-time version
  for f in bars  #run through the bars
    beats_per_bar.times do
    tick  #tick at 1/8
    if f
      sample :drum_bass_hard if pattern1.look
      sample :drum_snare_hard if pattern2.look
      sample :drum_cymbal_closed if pattern3.look
      sample :drum_cymbal_open if pattern4.look
    end
    sleep 0.5  #1/8
  end
end

Live_loop version:

  #Live_loop version
  live_loop :beat do
    tick  #tick at 1/8
    tick(:bar) if (bools *(knit 1,1,0,beats_per_bar-1)).look
    if bars.look(:bar)
      sample :drum_bass_hard if pattern1.look
      sample :drum_snare_hard if pattern2.look
      sample :drum_cymbal_closed if pattern3.look
      sample :drum_cymbal_open if pattern4.look
    end
    sleep 0.5
  end

Also a link to the stream, this parts starts at 57:00
