私はpyfluidsynthを稼働させようとしています。問題は、ダウンロード ページで提供されているサンプル コードを実行することさえできないことです。関連するコードは次のとおりです。
import time
import fluidsynth
fs = fluidsynth.Synth()
fs.start()
sfid = fs.sfload("example.sf2")
fs.program_select(0, sfid, 0, 0)
fs.noteon(0, 60, 30)
fs.noteon(0, 67, 30)
fs.noteon(0, 76, 30)
time.sleep(1.0)
fs.noteoff(0, 60)
fs.noteoff(0, 67)
fs.noteoff(0, 76)
time.sleep(1.0)
fs.delete()
問題が何であるかはよくわかりません-私が知る限り、すべての依存関係がインストールされていて、そうでないものはありません。エラーメッセージに従います。
