feepogram¶ ↑

A tiny DSL for non-trivial bloopsaphone projects.

require 'bloops'
require 'feepogram'

bloops = Bloops.new
bloops.tempo = 320

song = Feepogram.new(bloops) do
  sound :crunch, Bloops::NOISE do |s|
    s.punch = 0.5
  end

  sound :oooo, Bloops::SINE do |s|
    s.sustain = 2.0
  end

  sound :plink, Bloops::SQUARE do |s|
    s.punch = 1.0
  end

  def and_one
    phrase do
      oooo   " 1:c2 " * 8
      plink  " c d e f g a b + c - " * 4
    end
  end

  def and_two
    phrase do
      crunch " c2 4 c5 4 " * 8
      oooo   " 1:g2 " * 8
      plink  " c d e f g a b + c - " * 4
    end
  end

  2.times do
    and_one
    and_two
  end
end

song.play

sound initialises a bloopsaphone sound and defines a handy method for you. That’s not the interesting part.

phrase defines a 32-beat phrase. Any instruments to which you don’t assign a tune in the block are told to rest for 32 beats.

This makes it easy to decompose sections of your song into methods and repeat or comment out calls to them, which is something you’ll definitely want to be doing if your song is more than 10 seconds long.

Yeah, that’s it. There’s definitely potential for more though! Like, well, I don’t know. Potential, though.
