Does anyone know how to install fluidsynth or pyfluidsynth on windows 10? AttributeError: module 'fluidsynth' has no attribute 'Synth'

Question

I've tried to install fluidsynth and pyfluidsynth on windows 10 so many times in order to let magenta.music function play_sequence(note_seq,synth=mm.fluidsynth) play a note sequence and show it on my jupyter notebook.

I tried to clone the github repository, install it with pip, but nothing seems to work. I check that Synth class was on my fluidsynth.py script and I found it so I don't know where is the problem.

The error I get is this one:

Answer 1

For Windows, you have to:

1. Build it: https://github.com/FluidSynth/fluidsynth/wiki/BuildingWithCMake#building-with-msys2-on-windows (cause it is installed on os, not on python)

2. Then in your IDE terminal (let's say PyCharm) type: pip install --upgrade pyfluidsynth

3. You can also install pretty_midi for later usage (pip install pretty_midi)

Answer 2

I am just now, trying the instructions from here: https://ksvi.mff.cuni.cz/~dingle/2019/prog_1/python_music.html

the package is here: https://github.com/FluidSynth/fluidsynth/releases/tag/v2.1.0.rc1
