           Summary: UTAU singing voice synthesizer fails to generate wav
                    file
           Product: Wine
           Version: 1.3.4
          Platform: x86
        OS/Version: Linux

Created an attachment (id=31139)
 --> (http://bugs.winehq.org/attachment.cgi?id=31139)
Output with "No batch file" checked

Getting and installing the program:
Program download on http://utau2008.xrea.jp/ by clicking on the link that says
"v0.2.76 インストーラ"

The program is in Japanese, but there's an English translation here ->
http://utau.wikia.com/wiki/UTAU_wiki:UTAU_GUI_Translation

I installed the program with
$ LANG="ja_JP.UTF-8" wine utau0276inst.exe

It won't work without setting the LANG environment to Japanese, because it
generates the default voicebank with Japanese filenames.
I went forward accepting all the default values.
Then I copied the res folder of the English translation in the installation
directory (the bug happens even without adding the translation, so it's not
related).

Steps to reproduce:

Launch the program like this
$ LANG=ja_JP.UTF-8 wine "C:\Programmi\UTAU\utau.exe"
Click the pencil button and place some notes on the piano roll.
Select the notes.
Press the play button.



The program doesn't play any note, and gives a "Failed to generate a wav file.
Please check settings." error message.
No settings I could try managed to solve the problem, but I noticed the program
has a slightly different behavior depending on the value of the "No batch file
for rendering" option in Tools->Option...->General

- With the option checked, the output of the resampler.exe tool (which does
pitch manipulation of the voice samples) is shown in the console and a bunch of
wav files corresponding to the notes are generated in the cache directory.

- With the option unchecked, it doesn't generate any wav file in the cache dir
and tries to execute wavtool.exe (which I believe applies the envelope to the
rendered samples) on wav files that don't exist (probably because the previous
step failed). 

Either case, it eventually shows the above mentioned error and it doesn't play
anything.

I have a log file for both cases. The output of Wine and the one of the program
are mixed together in the files, I don't know how to set them apart, sorry.
