Create scale

scale  tonic (symbol), name (symbol)

Creates a ring of MIDI note numbers when given a tonic note and a scale name. Also takes an optional num_octaves: parameter (octave 1 is the default). If only passed the scale name, the tonic defaults to 0. See examples.

Introduced in v2.0

Examples

# Example 1

puts (scale :C, :major)

# returns the following ring of MIDI note numbers: (ring 60, 62, 64, 65, 67, 69, 71, 72)

# Example 2


play_pattern (scale :C, :major)

# anywhere you can use a list or ring of notes, you can also use scale

# Example 3


play_pattern (scale :C, :major, num_octaves: 2)

# you can use the :num_octaves parameter to get more notes

# Example 4


puts (scale 50, :minor)
puts (scale 50.1, :minor)
puts (scale :minor)

# Scales can start with any note:
#=> (ring 50, 52, 53, 55, 57, 58, 60, 62)
#=> (ring 50.1, 52.1, 53.1, 55.1, 57.1, 58.1, 60.1, 62.1)
#=> (ring 0, 2, 3, 5, 7, 8, 10, 12)

# Example 5


live_loop :scale_player do
  play (scale :Eb3, :super_locrian).tick, release: 0.1
  sleep 0.125
end

# scales are also rings

# Example 6


live_loop :scaled_sample do
  sample :bass_trance_c, rpitch: (scale 0, :minor).tick
  sleep 1
end

# scales starting with 0 are useful in combination with sample's rpitch:
