Zen

Translation

The laser beams sliced through the wafts of smoke as the subwoofer pumped bass deep into the bodies of the crowd. The atmosphere was ripe with a heady mix of synths and dancing. However something wasn't quite right in this nightclub. Projected in bright colours above the DJ booth was futuristic text, moving, dancing, flashing. This wasn't fancy visuals, it was merely a projection of Sonic Pi running on a Raspberry Pi. The occupant of the DJ booth wasn't spinning disks, they wrote, edited and evaluated code. Live. This is Live Coding.

live_loop :rand_surfer do
use_synth :dsaw
notes = (scale :e2, :minor_pentatonic, num_octaves: 2)
16.times do
play notes.choose, release: 0.1, cutoff: rrand(70, 120)
sleep 0.125
end
end
 
Now, when you play this, you'll hear a constant stream of random notes from the scale `:e2 :minor_pentatonic` played with the `:dsaw` synth. "Wait, wait! That's not a melody", I hear you shout! Well, here's the first part of the magic trick. Every time we go round the `live_loop` we can tell Sonic Pi to reset the random stream to a known point. This is a bit like going back in time in the TARDIS with the Doctor to a particular point in time and space. Let's try it - add the line `use_random_seed 1` to the `live_loop`:
 
live_loop :rand_surfer do
use_random_seed 1
use_synth :dsaw
notes = (scale :e2, :minor_pentatonic, num_octaves: 2)
16.times do
play notes.choose, release: 0.1, cutoff: rrand(70, 120)
sleep 0.125
end
end
 
Now, every time the `live_loop` loops around, the random stream is reset. This means it chooses the same 16 notes every time. Hey presto! An instant melody. Now, here's the really exciting bit. Change the seed value from `1` to another number. Say `4923`. Wow! Another melody! So, just by changing one number (the random seed), you can explore as many melodic combinations as you can imagine! Now, that's the magic of code.

This may sound like a far fetched story from a futuristic night club but coding music like this is a growing trend and is often described as Live Coding (http://toplap.org). One of the recent directions this approach to music making has taken is the Algorave (http://algorave.com) - events where artists like myself code music for people to dance to. However, you don't need to be in a nightclub to Live Code - with Sonic Pi v2.6+ you can do it anywhere you can take your Raspberry Pi and a pair of headphones or some speakers. Once you reach the end of this article, you'll be programming your own beats and modifying them live. Where you go afterwards will only be constrained by your imagination.
 
Live Loop
 
The key to live coding with Sonic Pi is mastering the `live_loop`. Let's look at one:
 
live_loop :beats do
sample :bd_haus
sleep 0.5
end
