🎶🐳 paramidib

paramidib is an easy way to make paramidi available with nimib. Install with nimble install paramidib.

It exports paramidi and provides two templates:

  1. saveMusic: takes a valid score for paramidi and creates a wav file with the generated music. It is adapted from paramidi_starter and it can be used even without nimib (paramidib itself does not depend on nimib).
  2. nbAudio: a new nimib block which create an audio control to play the wav file. In the following example is called with nbAudio("output.wav")
import paramidib

saveMusic("output.wav"):
  (piano,
    (tempo: 74),
    1/8, {-d, -a, e, fx}, a,
    1/2, {fx, +d},
    1/8, {-e, e, +c}, a,
    1/2, {c, e},
    1/8, {-d, -a, e, fx}, a, +d, +cx, +e, +d, b, +cx,
    1/2, {-e, c, a}, {c, e})

Another example where the score is a json object generated at runtime:

import json

let
  measure1 = %*[1/16, "b", "c+", 1/8, "d+", "b", "c+", "a", "b", "g", "a"]
  measure2 = %*[1/16, "g", "g", 1/8, "g", "a", "b", "c+", "d+", "c+", 1/2, "b"]
  measure3 = %*[1/16, [{"mode": "concurrent"}, "d", "b-", "g-"], [{"mode": "concurrent"}, "d", "b-", "g-"],
                1/8, [{"mode": "concurrent"}, "d", "b-", "g-"], [{"mode": "concurrent"}, "e", "c", "g-"],
                [{"mode": "concurrent"}, "d", "b-", "g-"]]
  measure4 = %*[1/16, "r", "r", 1/8, "g", "r", "d", "r", "g", "g", "d"]
  measure5 = %*[1/4, "g", 1/8, "a", "b", 1/4, "g", 1/8, "a", "d"]
  measure6 = %*[1/4, "g", 1/8, "a", "b", 1/4, "g", 1/8, [{"mode": "concurrent"}, "f", "a-"], "b", 1/4, "c"]

  score* =
    %*[{"tempo": 80, "octave": 3},
      ["guitar", measure1],
      ["banjo", measure1],
      ["guitar", measure1],
      ["guitar", 1/2, "d", 1/8, "g", "g", "a", "b", "g", "b", 1/2, "a"],
      ["banjo", 1/8, "g", "g", "a", "b", 1/2, "g"],
      ["guitar", {"octave": 2}, measure2],
      ["banjo", measure2],
      ["guitar", {"octave": 2}, measure2],
      ["banjo", measure2],
      ["guitar", measure2],
      ["banjo", measure2],
      {"octave": 4},
      ["guitar", measure3],
      ["banjo", measure3],
      ["guitar", measure3],
      ["banjo", measure3],
      ["guitar", {"octave": 2}, measure1],
      ["banjo", {"octave": 3}, measure1],
      {"tempo": 120, "octave": 3},
      [{"mode": "concurrent"},
        ["banjo", measure1],
        ["guitar", measure4]],
      [{"mode": "concurrent"},
        ["banjo", measure1],
        ["guitar", measure4]],
      [{"mode": "concurrent"},
        ["banjo", measure1],
        ["guitar", measure5]],
      [{"mode": "concurrent"},
        ["banjo", measure1],
        ["guitar", measure6]]]
