AMCJ #007「実践！ライブコーディング」
- Alex McLeanさんは完全ライブコーディング
- Kindohmさんはあらかじめ書いたコードに書き足し?
どちらも一長一短。
- 完全ライブコーディング
- 完全な即興から生まれるスリリングな状況の共有
- かなりの熟練が必要
- プリ・コーディング
- 展開の素早さ、DJ的
- あまり作り込み過ぎると面白みがない
今回のライブはかなりプリ・コーディング寄り
SuperColliderの起動ファイル
startup.scd
//TidalCyclesからのOSC送出(oFとの連携用)
var addr = NetAddr.new("127.0.0.1", 3333);
OSCFunc({ |msg, time, tidalAddr|
var latency = time - Main.elapsedTime;
msg = msg ++ ["time", time, "latency", latency];
addr.sendBundle(latency, msg)
}, '/play2').fix;
s = Server.local;
s.reboot {
s.options.numBuffers = 1024 * 16; //バッファサイズ
s.options.memSize = 8192 * 16; //メモリサイズ
s.options.sampleRate = 48000; //サンプリングレイト
s.volume = -6.0; //音量
s.latency = 2.0; //レイテンシー
//SuperDirtの初期設定
s.waitForBoot {
//チャンネル数の設定
~dirt = SuperDirt(2, s);
//SuperDirt付属のサンプル読み込み
~dirt.loadSoundFiles;
//独自サンプル読み込み
~dirt.loadSoundFiles("C:/Users/tado/AppData/Local/SuperCollider/downloaded-quarks/samples-extra/*");
//bootするまで待機
s.sync;
//SuperDirt起動
~dirt.start;
}
}ポイント
- OSCによるoFとの連携
- SuperColliderが起動したらすぐにSuperDirtを起動するように
- SuperDirtのデフォルトのサンプルを読み込んだ後で、自分で追加したオリジナルサンプル読み込み
Windows 10のTips
- 起動して最初のbootに時間がかかる場合
- Windows Securityの例外にSC関連のプロセスを入れておく
ライブの際のコードを説明する前に、基本事項の確認
ノリ(グルーブ)の源泉、シンコペーション
d1 $s "bd hc bd cp" #cps(70/120) -- シンプルすぎる!
d1 $s "bd hc [~ bd] cp" -- シンコペーションによるグルーブ
d1 $s "bd [~ hc] [~ bd] cp" -- さらにシンコペーション
d1 $s "bd [~ hc] [~ bd] [~ [~ cp]]" -- やりすぎは良くないループ単位で変化させる
d1 $s "bd <~ hc [~ hc]> [~ bd] <cp cp*4 ~ [hc*2 ho]>" -- <>の中を順番に2つのパートの共存
d1 $s "{bd hc [~ bd] cp, ho [~ ho] ho [~ ho*2]}"パターンの上部でリズムに変化をつける
- jux, brak, fast, slowなど
d1
$jux (iter 8)
$s "{bd hc [~ bd] cp, ho [~ ho] ho [~ ho*2]}"変化のタイミングを設定
- sometimes, sometimesBy, every, whenmod など
d1
$sometimesBy 0.3 (jux (iter 8))
$sometimes brak
$every 4 (fast 2)
$s "{bd hc [~ bd] cp, ho [~ ho] ho [~ ho*2]}"パターンの下でエフェクトをつける
- delay, room, shape, gainなど
d1
$every 6 (slow 2)
$sometimesBy 0.3 (jux (iter 8))
$every 4 (fast 2)
$s "{bd hc [~ bd] cp, ho [~ ho] ho [~ ho*2]}"
#delay "0.5" #delayt "1.5" #delayfb "0.5"

#delay "0.5" #delayt "1.5" #delayfb "0.5"
#lpf (range 100 10000 $slow 4 $sine)
#resonance "0.2"
#shape "0.7"変拍子、ポリリズム、ポリミーター
変拍子 (4で割り切れないリズム)
d1 $s "bd hc bd cp cp" -- 5拍子
d1 $s "bd ~ hc bd cp ~ cp" -- 7拍子変拍子にリズム変化
d1
$sometimesBy 0.3 (rev)
$jux (iter 14)
$s "bd ~ hc bd cp ~ cp" -- 7拍子ポリリズム、複数のリズムの共存
d1 $s "[bd ~ hc bd cp ~ cp, bd hc bd ho]" -- 7 + 4拍子ポリリズム + リズム変化
d1
$every 3 (rev)
$sometimesBy 0.3 (jux (iter 14))
$s "[bd ~ hc bd cp ~ cp, bd hc bd ho]"
#lpf (range 100 10000 $slow 4 $sine)
#resonance "0.2"ポリミーター、複数のリズムのタイミングがずれていく
d1 $s "{bd ~ hc*2 bd cp ~ cp*3, bd ~ hc cp}" -- 7 + 4拍子ポリミーター + リズム変化
d1
$every 3 (rev)
$sometimesBy 0.3 (jux (iter 14))
$sometimesBy 0.4 (slow 2)
$s "{bd ~ hc*2 bd cp ~ cp*2, bd hc hc cp}"
#lpf (range 100 10000 $slow 4 $sine) #resonance "0.2"
#shape "0.5"
#cps(75/120)ユークリッドリズム(便利!!)
d1 $s "cp(3, 8)"
d1 $s "cp(5, 8)"ユークリッドリズムの理屈
-
(3, 8)の場合
- [1 1 1 0 0 0 0 0] (3, 8)
- [1 0][1 0][1 0][0 0] 1と0をペアに
- [1 0 0][1 0 0][1 0] 右に余った0を左から順に入れていく
- [1 0 0 1 0 0 1 0] 完成
-
(5, 8)の場合
- [1 1 1 1 1 0 0 0]
- [1 0][1 0][1 0][1 1] 1と0をペアに
- [1 0 1][1 0 1][1 0] 余った1を配分
- [1 0 1 1 0 1 1 0] 完成
