pyfluidsynth上树莓派错运行

Question

试图初始化fluidsynth当我尝试播放MIDI从一个树莓派我的Python程序的声音，但是，它errrors：

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

引起以下错误：

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

我想最后的消息可以通过启动杰克服务器是固定的，但我不能修复

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

错误

任何人都知道如何？

Answer 1

默认的fluidsynth设置显然不适用于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中执行此操作，请从命令行手动启动fluidsynth，并告诉您的Python程序输出到fluidsynth的端口。
