Type: binary :: Pattern Int -> Pattern Bool

binary allows you to express a boolean pattern as a decimal number.

For example `163` in binary is `10100011`, and so these are equivalent:

d1 $ struct (binary 163) $ sound "clap:4"

d1 $ struct "t f t f f f t t" $ sound "clap:4"

That number can be patterned:

d1 $ struct (binary ("163 63")) $ sound "clap:4"

binaryN

Type: binaryN :: Int -> Pattern Int -> Pattern Bool

binaryN lets you specify a number of bits for the pattern. For example 55532 gives the boolean pattern 1101100011101100:

d1 $ struct (binaryN 16 55532) $ sound "bd"

ascii

Type: ascii :: Pattern String -> Pattern Bool

Turns characters into 8-bit binary patterns, using their ASCII encoding. E.g. the letter 'a' give the binary pattern 01100001.

d1 $ struct (ascii "<[a b] [c d] [e f] [g h]>") $ sound "bd" # speed 2
