midi modules not useable if fluidsynth is not installed

[GoogleCodeExporter]

In Python 2.5, when I try 'import mingus.midi.MidiFileOut', I get the 
following:

   import mingus.midi.MidiFileOut
  File "C:\Python25\Lib\site-packages\mingus\midi\__init__.py", line 28, in 
<module>
    import fluidsynth
  File "C:\Python25\Lib\site-packages\mingus\midi\fluidsynth.py", line 43, 
in <module>
    import pyFluidSynth as fs
  File "C:\Python25\Lib\site-packages\mingus\midi\pyFluidSynth.py", line 
27, in <module>
    _fl = CDLL(find_library('fluidsynth'))
  File "C:\Python25\lib\ctypes\__init__.py", line 348, in __init__
    self._handle = _dlopen(self._name, mode)
TypeError: expected string or Unicode object, NoneType found

I don't have fluidsynth installed, but shouldn't the midi file classes work 
without it?

You're right, fluidsynth shouldn't load. Thanks for letting me know. I fixed 
the bug
in mingus.midi.__init__. You can update your local copy or download version 
0.3.7.9.

I have a similar problem :

Traceback (most recent call last):
  File "C:\Python25\mingus_examples\pygame-piano\pygame-piano.py", line 45, in <module>
    from mingus.midi import fluidsynth
  File "C:\Python25\Lib\site-packages\mingus\midi\fluidsynth.py", line 43, in <module>
    import pyFluidSynth as fs
  File "C:\Python25\Lib\site-packages\mingus\midi\pyFluidSynth.py", line 27, in <module>
    _fl = CDLL(find_library('fluidsynth'))
  File "C:\Python25\lib\ctypes\__init__.py", line 348, in __init__
    self._handle = _dlopen(self._name, mode)

That means the FluidSynth library can't be found. If you haven't installed it, 
then
do so. If you are on windows then be sure to check the installation 
instructions that
you can find in the wiki (because then you need to download qsynth and rename 
the dll).
