はじめに
こんにちは、ファイナンシャル・プランニング技能士です。ちょっと最近普通のプログラミングとは別にオーディオプログラミングとかヴィジュアルアートプログラミングとかで遊びたいなーと思いはじめてたところに、TLでTidalCyclesを見かけました。うまくSuperColliderをラップしてて面白そうなので、とりあえず環境構築をしてみることに。
Arch Linux
SuperColliderをインストール
普通にパッケージがあるのでインストール。
% pacaur -S supercollider sc3-plugins
stackを使ってtidalのインストール
公式サイトのインストール手順 に書いてあるとおりに適当に進めてみたら、家のArchでは cabal install tidal でいろいろ設定をいじってもインストールできなかった。ArchのpacmanでインストールするGHCがデフォルトだと動的リンクをするのに対し、cabalでのデフォルトの設定が静的リンクになっているせいかとも思ったが、設定を変えるても失敗するのでstackで入れることにした。
% pacaur -S stack % stack setup % stack install tidal
SuperDirtのインストール
インストール手順にあるようにSuperColliderを起動して、エディターに include("SuperDirt") を入力して実行。するとPost Windowにインストールログが流れ始めてインストール作業が行われていることがわかる。

SuperDirtの起動に失敗するのでjackdを手動で起動
手順どおりに SuperDirt.start を実行するとオーディオを正しく起動できなかったとエラーメッセージが出る。

RESULT = 0
ちょっと調べた結果、どうもSCで利用しているjackdが正しく起動出来ていないようなので、手動でjackdを起動する。

改めて SuperDirt.start を実行するときちんと起動できた。

Atomの設定とテスト
Atomをインストールして、tidalcyclesパッケージをインストール。中で呼び出すghciの起動コマンドの設定があるので、そこを stack ghci に変更しておく。
その上で、 Packages > TidalCycles > Boot TidalCycles を実行する。インストール手順書にあるように次のコードをEvalしてみて音がなったら成功。
d1 $ sound "bd sn"
jackdとSuperColliderの起動のスクリプト化
一応これで動いたけれど、jackdを手動で起動して、かつSuperDirtの起動のためだけにSuperColliderのIDEを起動するのは大げさなので、スクリプト化してターミナルだけで完結するようにする。
まず start.scd という名前でSuperDirt.startを呼ぶだけのコードを保存しておく。
( SuperDirt.start )
次に先ほどのjackdの起動とstart.scdの読み込みだけの簡単なシェルスクリプトを用意する。
#!/bin/bash jackd -r -d alsa & sclang start.scd
これのシェスクリプトを起動すればいちいちSuperCollider IDEを起動しなくて良くなる。終わったあとはjackdをちゃんとkillしないと音声を出すアプリケーションが動かなくなるので注意。
