Instead of clipping, they reduce the overall volume, which sounds bad with music.
You can avoid it by using WASAPI or ASIO.
BTW about a half year ago I made a test code for master volume. tp://yyagi.com/DTXMania_34712_mastervolume_trial.zip
It works only for ASIO, but not for WASAPI. To support WASAPI, I need furthur investigations.
now CONFIGURATION/System/MasterVolume takes effect for both WASAPI/ASIO

Thanks for the information about WASAPI/ASIO. It seems like they really don't change the volume.
Although there is a different problem with WASAPI/ASIO, the bgm is not synchronised anymore. It's playing too early. (By a small amount) (Tested bgm is Ogg vorbis WAVE)
What could this be related to? They both have it. For ASIO, I use ASIO4ALL v2.
About the master volume, it seems to work, but it only works with WASAPI/ASIO?
>Although there is a different problem with WASAPI/ASIO, the bgm is not synchronised anymore. It's playing too early.
Maybe... it causes because the lag is differnt between DirectSound and WASAPI/ASIO.
DirectSound has bigger lag, but many DTX data creators adjusted BGM with DirectSound (DTXV uses DirectSound), so you feel "too early" when you use WASAPI/ASIO (smaller lag).
To adjust BGM timing, please use BGMAdjust feature in playing screen.
The settings is memorized for each dtx files.
Actually it's ripped and should be perfectly synced. (I have checked the Wave of these songs multiple times, and the timings should be correct...)
Is there a difference in sync for you when using DirectSound instead of WASAPI/ASIO?
Here's a DTX that I have this problem with: ht tps://www.mediafire.com/?30sk949va3a3gl4
Adjusting the BGM for every song would be a little bit annoying, but I guess it's a possibility.
I could not play your problemed DTX data. (No BGM playback.)
I know BGM uses WAV format and it contains vorbis codec data. It seems my Win8 x64 can't handle it.
Could you recommend me proper codec to playback?
I have tried "ogg vorbis codec for msacm 0.0.3.6", but it doesn't work well.
It needs to be installed manually for 64-bit systems.
Here is an english description of how to do it: ht tp://pastebin.com/q2UABEG6
Oops, your pastebin seems erased ... but your hint is great help for me. At last I could install vorbis codec for x64 by tp://ameblo.jp/true-shootingstar/entry-11142859506.html
and I could repro your issue. (1 beat skipped in overture)
If you encounter this issue, please set CONFIGURATION/UseOSTimer=OFF, or AdjustWaves=OFF. (I recomment former setting)
It's not that much for me, the BGM is only about 0.1s early at most.
The DTX is actually not so good for testing, because it uses weird BPM. But I've calculated the timing anyways:
((60 / 131.004) * 3) + ((60 / 135.003) * 5) = 3.59617668781 (This is the beginning of Bar # 002)
Here is a screenshot of that timing in the wave: tp://i.imgur.com/qFU1wlt.png
That is how it sounds like in DSound. (Which is good and in sync)
When choosing WASAPI (or ASIO), the timing seems to be AFTER the peak. (So the chips will be after the BGM)
In the song's BGM, at this point there is a kind of snare click sound (in pairs of two, twice per measure), so it's easy to hear if it's too early.
I've tried changing the settings, but it did not change anything. (UseOSTimer was always off, AdjustWaves doesn't seem to change anything.)
By the way, my pastebin still works for me. Strange.
Implemented in the release101.

It would be useful to have a setting for the master volume of DTXMania, which changes the overall volume of the sound.
The reason I'm asking for this is Windows 7. It seems like they changed the handling of sound when it exceeds the maximum volume. (Compared to XP)
Instead of clipping, they reduce the overall volume, which sounds bad with music.
I know that in Windows 7 the volume can be changed separately for each application, but it doesn't prevent this behaviour.
Here is a recording of the problem including the test DTX: ht tps://www.mediafire.com/?cc63h3d3ycuw62k
Although I'm not certain that this is a Windows 7 problem and not my system's fault, it was confirmed by another person.
When lowering the "Chip Volume" and "Auto Volume" in DTXMania, it helps to prevent the unwanted volume changes. So I guess lowering the master volume and increasing Windows 7 system volume would help.
Anyways, I think it's a useful feature regardless of this problem.
