Tutorial 2: Algorithmic Manipulation

The code below plays the first four notes of the default scale on repeat:

p1 >> pads([0,1,2,3])

It’s possible to manipulate this by adding an array of numbers to the Player object This raises the 4th note played by 2 degrees

p1 >> pads([0,1,2,3]) + [0,0,0,2]

And this raises every third note by 2

p1 >> pads([0,1,2,3]) + [0,0,2]

These values can be laced and grouped together

p1 >> pads([0,1,2,3]) + [0,1,[0,(0,2)]]

This behaviour is particularly useful when using the follow method.

b1 >> bass([0,4,5,3], dur=2)
p1 >> pads().follow(b1) + [2,4,7]

You can schedule players to do things This will tell p1 to reverse the notes every 4 beats

p1 >> pads([0,2,4,6])
p1.every(4, "reverse")

You can “chain” methods together by appending them to the end of the original line:

p1 >> pads([0,2,4,6]).every(4, "reverse")

To stop calling “reverse”, use never:

p1.never("reverse")

Here are a few other methods you can use:

Using stutter will play the same note n number of times with different attributes specified

p1.every(4, "stutter", 4, oct=4, pan=[-1,1])

Rotate will move all the values over by 1 in their order

p1.every(4, "rotate")

To randomise the order of the notes, use shuffle

p1.every(4, "shuffle")
