Pattern Constructors

The following functions will return a pattern. These are the equivalents used by the Mini Notation:

function	mini
`cat(x, y)`	`"<x y>"`
`seq(x, y)`	`"x y"`
`stack(x, y)`	`"x,y"`
`timeCat([3,x],[2,y])`	`"x@3 y@2"`
`polymeter([a, b, c], [x, y])`	`"{a b c, x y}"`
`polymeterSteps(2, x, y, z)`	`"{x y z}%2"`
`silence`	`"~"`

cat

Synonyms: slowcat

The given items are concatenated, where each one takes one cycle.

items (any): The items to concatenate

cat(e5, b4, [d5, c5]).note() // "<e5 b4 [d5 c5]>".note()

You can also use cat as a chained function like this:

s("hh*2").cat(
  note("c2(3,8)")
)

seq

Synonyms: fastcat, sequence

Like cat, but the items are crammed into one cycle.

seq(e5, b4, [d5, c5]).note() // "e5 b4 [d5 c5]".note()

Or as a chained function:

s("hh*2").seq(
  note("c2(3,8)")
)

stack

Synonyms: polyrhythm, pr

The given items are played at the same time at the same length.

stack(g3, b3, [e4, d4]).note() // "g3,b3,[e4,d4]".note()

As a chained function:

s("hh*2").stack(
  note("c2(3,8)")
)

timeCat

Like Pattern.seq, but each step has a length, relative to the whole.

timeCat([3,e3],[1, g3]).note() // "e3@3 g3".note()

polymeter

Synonyms: pm

Combines the given lists of patterns with the same pulse. This will create so called polymeters when different sized sequences are used.

polymeter(["c", "eb", "g"], ["c2", "g2"]).note()
// "{c eb g, c2 g2}".note()

polymeterSteps

Aligns one or more given sequences to the given number of steps per cycle.

steps (number): how many items are placed in one cycle
sequences (Array.<any>): one or more arrays of Patterns / values

polymeterSteps(2, ["c", "d", "e", "f", "g", "f", "e", "d"])
.note().stack(s("bd")) // 1 cycle = 1 bd = 2 notes
// note("{c d e f g f e d}%2").stack(s("bd"))

silence

Does absolutely nothing..

silence // "~"

run

A discrete pattern of numbers from 0 to n-1

run(4).scale('C4 major').note()
// "0 1 2 3".scale('C4 major').note()
