概要

紹介

loop do
  a=File.read("/Users/???/SonicPi_Text_MidiNo.txt").to_f # 保存したファイルのフルパス名を与えます.
  b=File.read("/Users/???/SonicPi_Text_Amp.txt").to_f
  c=File.read("/Users/???/SonicPi_Text_Sleep.txt").to_f
  play a,amp: b
  sleep c
end
例
ファイル SonicPi_Text_MidiNo.txt の中身の例は、 60。　　60.5も可能
ファイル SonicPi_Text_Amp.txt の中身の例は、 1.0
ファイル SonicPi_Text_Sleep.txt の中身の例は 0.5
Sonic PiのプログラムをRunした後、テキストエディタ等でファイルの中身を書き換えて、"その都度保存"すると、Sonic Piの動作をリアルタイムに制御できます。

Sonic Pi --> Processing の例

Sonic Piで同時に鳴るランダムな２つの音の音程と音量をx,y,rとして３つのファイル（場所はProcessingプログラムのフォルダ中）に書き出す。
Processingで、ファイルから値を読み込んで、x、yを中心とし、rを半径とした円をランダムな色で描く。
リアルタイムではあるが、書き出す側と読み込む側の同期はしていない。

Sonic Pi側のプログラム
use_debug false
use_random_seed 0		# 乱数の種の番号。デフォルトは0
loop do
  x=rrand(48,96)		# MIDIノート番号48〜96 (C3〜C6)の音を実数の乱数で生成。x座標とする
  y=rrand(48,96)		# 同上。y座標とする。
  r=rrand(0.1,5)		# 0.1〜5.0の実数の乱数。音量とする。
  File.write("Processingプログラムへのパス/SonicPi_to_Processing/SPtest1.txt",x) # xの値をProcessingのプログラムフォルダ内のファイルに書き出す。
  File.write("Processingプログラムへのパス/SonicPi_to_Processing/SPtest2.txt",y) # yの値を　同上
  File.write("Processingプログラムへのパス/SonicPi_to_Processing/SPtest3.txt",r) # rの値を　同上
  play [x,y],amp:r		# x,yを同時に、音量rで鳴らす。
  sleep 0.25			# 0.25拍置く(デフォルト速度では0.25秒)
end

Processing側のプログラム
//  Sonic Piの２つの音とその強さの値をProcessingのdataディレクトリにファイル出力し、読み込んでグラフィック表示する。
//  Sonic Pi側の書き込み中にProcessing側で読み込むと値がないファイルとなってエラーするため、読み込んだ配列の長さが０かどうかを調べている。

void setup() {
  size(600, 600);	# 画面サイズ
  background(0);	# 背景色を黒に
  strokeWeight(5);	# 線の太さを5ピクセルに
  colorMode(HSB);	# 色モデルをHSBに
  frameRate(5);	# 画面の更新速度を5回/秒に
}

void draw() {
  float x=0,y=0,r=0;
  fill(0,2);		# 塗り色を黒、透明度を2に(0が完全透明,255が不透明)
  rect(-5,-5,width+10,height+10);	# 画面全体を薄い半透明の黒の四角形で塗りつぶす
  String[] s1 = loadStrings("SPtest1.txt");	# SonicPiで書き込んでいる値をファイルから読み込む,x
  String[] s2 = loadStrings("SPtest2.txt");	# 同上,y
  String[] s3 = loadStrings("SPtest3.txt"); # 同上,r
  
  if(s1.length>0) x=(float(s1[0])-48+1)*width/48.; # 画面サイズに合わせてx座標を作成する。ファイルが空の場合は配列の長さがゼロとなっているので、座標を生成しない。
  if(s2.length>0) y=(float(s2[0])-48+1)*height/48.; # 同上 y
  if(s3.length>0) r=(float(s3[0]))*20.0; # 同上、半径r
  fill(random(255),255,255);	# 塗り色の色相をランダムに設定。彩度と明度は最大。
  stroke(random(255),255,255);	# 同上、線の色
  ellipse(x, y, r, r);	# 円を描く
//  println(x+" "+y+" "+r);
}


Processing --> Sonic Pi の例
Processing側で、マウスで画面をクリックした場所に円を描く。円の座標を２つの音程とし、円の半径はクリックしていた時間から生成し、それを音量とする。これら３つの値を３つのファイルに書き出す。
Sonic Pi側で３つのファイルを読み込み、２つの音を少しずらして鳴らし、読み込んだ音量で鳴らす。鳴らす間隔は1/4拍に固定。
リアルタイムではあるが、２つのプログラムは、同期していない。

Processing側

}

  ellipse(mouseX,mouseY,r*30,r*30); // マウスの座標に音量を直径として円を描く
  println(x+"     "+y+"     "+r);

5行のプログラムで、1000000桁や10000000桁の円周率音楽, Pi Music

いろいろな数字を用いた音楽が作られていますが、その中でも円周率は古くから多くの人によって音楽とされているようです。 Sonic Piでは、Rubyのファイル読み込み機能を使って数字や文字をファイルから簡単に読み込むことができます。 複数行のファイルの場合は、行単位に配列の要素として読み込むことができます。ここでは、円周率を全て１行に並べているテキストファイルを一つの文字列として読み込んで利用しています。
読み込んだ文字列から、一文字づつを取り出して、整数に変換してから値を２倍して、中央のド(MIDIノート番号60)に加えて音程として使用しています。

円周率100万桁が改行なしに入力されている"pi1000000.txt"は、

プログラムは、下記の５行と非常に簡単に記述できます。
pi=File.open("ファイル pi1000000.txt へのパス").read  # ファイルの置き場所は任意.　デスクトップ等でも可.
for i in 0...pi.length
  play pi.slice(i, 1).to_i*2+60
  sleep 0.125
end
この設定では、演奏の完了には約３７時間かかります。

二桁ずつ取り出すなどの改良も容易です。
for i in (0...pi.length).step(2)
  play pi.slice(i, 2).to_i+40
  sleep 0.125

五度円(五度圏)上を廻るコード

完全五度の関係にある調を順に並べて行くと12の調からなる円になります。隣り合ったコード同士は相性が良く３つ並んだ３コードで曲が作られたりしています。
以下のプログラムでは、Cから始め、左側、現在と同じ、右側、を乱数の-1,0,1で決めてランダムに移動します。移動量は12で割った余りをつかっていますので１オクターブ内を移動します。音はコードで２音ずつ鳴らしています。

# Random walk around on the Circle of Fifth
use_debug false
use_random_seed Time.new.usec
use_synth :pluck
i=0
loop do
  2.times do
    play_pattern_timed (chord 48 + i%12, :major),0.01
    puts i/7, note_info(48 + i%12)
    sleep 0.5
  end
  i=i+(rrand_i(0,2)-1)*7
end

時々、+9または-3して対応するマイナーコード(:minor)(円の内側)にするなども容易にできる改良です。

リサージュ図形のいろいろ

Sonic Piでは、左右の音の位相のズレをXY軸としてグラフ表示をしてくれます。
グラフの表示は、［Prefs］ボタンから［ビジュアル］→[Lissajous]をチェック.
左右にpanを振って適当な整数比となる周波数を与えると図形を観察することができます。
release時間(デフォルト設定のまま)によって図形がうまく重なって移行してくれました。

プログラムは、

a=[[600,600],[600,550],[600,500],[600,400],[600,300],[600,200]]
for i in 0...a.length
  play hz_to_midi(a[i][0]),amp:3,sustain:2,pan:-1
  play hz_to_midi(a[i][1]),amp:3,sustain:2,pan:1
  sleep 2
end

配列中の周波数[ , ]の左右を入れ替えると、グラフのXY軸が交換します。panの値の入れ替え(1と-1)でも同様です。

このプログラムの解説とver.2.12の機能を使い大幅に拡張したプログラムの解説したYoutubeビデオを英国のRobin Newmanさんが公開しています。
改良版のコードも公開されています。

Sonic Piによる奏者の発音タイミングデータの活用(Miles Davis "So What")

Miles DavisのSo Whatの冒頭のトランペットソロの部分の演奏を利用しています。

作成方法の概略
1) AudacityまたはSoinc Visualiserのスペクトル表示機能を利用して発音の開始時間をラベルとしてマーク（目視）し、ラベルファイルとして出力します。(テキストファイルが得られます)
下図は、Audacityで読み込んだMilesのソロの出だしのD5,A4,D4の部分にラベルを付けたところ.(マウスでクリックしてcommand+B, Winではcontrol+B)
ここでは、基音よりも２倍音の成分の方が大きく見えており、これは聴感上と一致すると思われますので、基音でなく２倍音の開始位置を選んでラベルを付けています。
３倍音以上も、スケールを変えて目視確認はしましたが、基音または２倍音よりも大きくなることはありませんでした。

2) Excel等で各時間の差をとって横並びにしてカンマで区切り、音符の長さとする。このとき要素の先頭と最後だけは後で調整します。
これが下記の配列bとなります。

3) MIDIデータWebから入手しをMuseScoreで読み込み、演奏に合わせて楽譜を修正します。(このとき、音の長さ、休符は使用しないので考慮するは必要ありません)
MuseScoreで作成されたMilesのソロの先頭部分の例。上記のスペクトルに対応

4) MuseScoreでMusicXML形式に出力し、本サイト内で公開しているProcessingによる変換プログラムでSonic Piの音符に変換します。
5) 出力された音符のデータから休符":r,"を全て削除してから、先頭にのみ加えると下記の配列aが得られます。

6) これらの作業は、一回で音程データと時間データが一致することはありませんでした。演奏させてみて、ずれた部分を探しての修正を繰り返すことになります。
作業1)では、楽譜には記述されない、小さな音を拾うか捨てるか迷うことがありました。この部分は、演奏の解析にも活用できるでしょう。同じ音程の音でも、整数次倍音が優勢な音と奇数次倍音が優勢な音なども観察できます。（トランペットは構造上、奇数次倍音が優勢な楽器と言われています。）


この作業では、音の強さは考慮していません。
#でコメント化してある２行は、別途作成したマイルスの元演奏のソロ開始の少し前から切り出したWAVファイルを同時に再生するためのものです。
この目的のために、配列bの先頭を 5.31秒 と長くしていますので、適宜0.31等に書き換えて下さい。
スペクトルの表示色の設定により音として見える大きさが異なり、また、色の変化から目視で発音のタイミングを得ているので、ある程度の誤差はありますが、元演奏にほぼピッタリと合ったタイミングでSonic Piが演奏してくれます。
スペクトル表示の設定を操作すると、赤く見える部分の大きさが変わります。スペクトル表示前に、コンプレッサ（マキシマイザー）を強くかけて音量を揃えておくのも一つの方法と考えられます。
楽器をpianoにすると、フェイクの様子がより鮮明になります。
完全なソロ演奏の場合は、作業が比較的に容易です。DebussyのSyrinxもデータは作成済みで公開予定（演奏者は、Moyse, Gazzelloni, Galway, Phaud etc.）

Sonic Piによるドビュッシーのシランクスの演奏。５人の巨匠の比較。Debussy, Syrinx

ジェームズ・ゴールウェイ James Galway 8:04- (2m17s)
エマニュエル・パユ Emmanuel Pahud 10:26- (3m23s).


コードとデータの作製法は、上記のSo Whatのプログラムとほぼ同様ですが、トリルの回数が演奏者によって大きく異なっているので、これにより音の総数も違ってきています。
音のタイミングの取得には、Sonic Visualiserを使用しました。(Audacityのスペクトルは使用せず) 目視によって音の出だしのタイミングをマークして数値として得ていますので、ある程度の誤差を含んでいます。
Youtubeのビデオ中で使用した音は、下記プログラムのampとreleaseとpanを音の長さによって少しだけ変化させるようにしています。
楽器をピアノ(use_synth :piano) とすると、余韻が減るため、一音一音の間隔がより際立って聴こえます。
play a[i][j]+1 というようにして半音上げ等の移調が簡単にできます。（半音上げると尺八で吹きやすくなり、+5程度で鼻笛で吹けるようになりますが、かなりの難曲です。）
使用ソフトウェアは、Sonic Pi, Sonic Visualiser, Audacity(音の切り貼り), MuseScore(楽譜からMusicXMLファイルの作成), ProcessingプログラムでMusciXMLをSonic Piの音符に変換、以上はOpen Source Software
ビデオ化には iMovie (Apple)を使用.

オープンソースソフトウェアだけで、このようなデータが作成できますので、音楽や演奏の解析等へのSonic Piのさらなる活用が期待されます。

Sonic Piを離れますが、
X軸を時間、Y軸を音程として５人の奏者を色分けしてプロットすると下記のようになります。まず、全長、最高音の部分、トリルの部分などの位置関係から眺めると興味深いものです。

X:Time , Y:Pitch , Black(Moyse), Red(Gazzelloni), Green(Rampal), Blue(Galway), Magenta(Pahud)

全演奏時間で正規化すると、ある程度類似点が見えてきますが、間の取り方は様々です。

X:Normalised Time , Y:Pitch , Black(Moyse), Red(Gazzelloni), Green(Rampal), Blue(Galway), Magenta(Pahud)

さらに、拡大してフレーズごとに比較するなど試してみると興味深いと思われます。

将棋の棋譜の音楽化 (Shogi Music)

# SonicPiによる将棋の棋譜ファイルの演奏
# Shogi game record music by Sonic Pi,  2018.4.1 Hiroshi Tachibana

# 棋譜データを読み込み、駒の動きを音にします。
# Sonic Piのログ表示領域を適当なサイズにしておくと、棋譜をテキストとして、盤面が静止した状態で観察しながら音を聞くことができます。
# 棋譜には、"CSA標準ファイル形式"を用います。(半角英数だけで表示できて簡便なのを利点と考えて採用)
# http://www.computer-shogi.org/protocol/record_v22.html

# 将棋盤は、右上が一１、左下が九９
# 一手の前後の動きのXY座標をそれぞれ、座標変化をポルタメントで変化させた２つの音として同時に鳴らし、先手の音を左側(pan:-1)、後手の音を右側(pan:1)としています。
# 駒の種類によってsynthの音色を変えています。成駒にはディストーションをかけました。
# 相手の駒を取った場合と駒台から打った場合には、特に別の音も鳴らしています。

# CSA規格中、盤面座標の数字は移動前と移動後の４桁連続のみ場合しか扱っていません。
# 対局データの開始は、先頭文字が%でなくなった時にしています。
# 最終行の判定は、先頭文字の+-が、%になった時にしており、途中に%行があるとそこで停止してしまいます。

# 棋譜ファイルの形式は CSA標準で、将棋DB2 https://shogidb2.com/ 等から入手できる。
#   棋譜表示画面の左下の [棋譜の書き出し]->[CSA形式] で表示し、コピーして保存する.

sleep時間のベンチマーク, Benchmark of the "sleep" time

４回実行すると、(real:実経過時間 , stime:System CPU time , utime:User CPU time)

となりrealは、60秒を少しだけ下回っていました。(ゼロであった子プロセス時間のcstime,cutimeは省略)
３つの値の和でも、
59.98347188
60.00179002
60.00114847
60.00187458
というばらつきがありました。


require 'benchmark'

では、
Sonic Piの出力は、{run: 1, time: 10.0}でしたが、
real=9.980002644471824
stime=0.004908999999999997
utime=0.021179000000000003
でした。和は、10.00609064
音楽での時間精度は、この程度で問題ないことと思われます。
波長の半分だけずらした２つの音を同時に鳴らすことによって音を消すというようなことができない時間精度だということがわかります。
