pyfluidsynth上樹莓派錯運行

Question

試圖初始化fluidsynth當我嘗試播放MIDI從一個樹莓派我的Python程序的聲音，但是，它errrors：

>>> import fluidsynth 
>>> import time 
>>> fs = fluidsynth.Synth() 
>>> fs.start() 

引起以下錯誤：

Cannot connect to server socket err = No such file or directory

我想最後的消息可以通過啓動傑克服務器是固定的，但我不能修復

Cannot connect to server socket err = No such file or directory 
Cannot connect to server request channel 

錯誤

任何人都知道如何？

默認的fluidsynth設置顯然不適用於Raspberry Pi。

更改audio driver settings以便使用alsa代替jack。

如果您不知道如何在Python中執行此操作，請從命令行手動啓動fluidsynth，並告訴您的Python程序輸出到fluidsynth的端口。
