Hi ,

Do others have the same issue after generating a song on Reaper/ Windows 11 ?


The plugin is very convenient for Reaper , but it crashes randomly just after the generation


Loading it in a separate process as Reaper permits avoid crashing the daw (as the plugin is loaded inside the reaper_host64.exe wrapper , only reaper_host64.exe crashes) , but still it is annoying to have to reload the plugin after the crash of reaper_host64.exe


Btw , I am using the VST2 version as VST3 does not send midi program change to my synt vsti, but I have the same issue with the VST3 version.

Also , I have tried another daw (vsthost) with the same issue.

Hi ,

FWiW , I have noticed that the process bbw4_64.exe is launched during song generation

I have tried to change its setting to run it as an administrator (same for processes reaper.exe and reaper_host64.exe) with no success.

Sorry my DAW is not eligable for Win11 otherwise, the BIAB-VST has been stable with Win10.

Gegu,

Welcome to the forum and to Band-in-a-Box. If you would like to help PG Music resolve the issue, there are several text file logs you can copy and post in the forum.

Use Notepad to create a blank text file. Save the blank file under the name "PreserveAllFiles.txt. Move the PreserveAllFiles.txt file to the BBPlugin directory at \bb\BBPlugin\PreserveAllFiles.txt.

The blank file instructs the plugin to keep all temporary input-output files. These files normally are generated on the fly then discarded. This allows you to look and copy them.

Some of the temporary files include:
BBoutput.txt
RBResults.txt
BBInput.txt
BBSong.txt

There are two locations where you may find useful information regarding crashes. They include:
\bb\Data\bbw4_PlugInLog.txt. Backend Errors messages can appear here. Backend is communication between the main Band-in-a-Box program and the plugin.
\bb\Data\bbw4_64exe_FlashMessageLog.txt
Flash messages are the yellow and green pop up messages that briefly appear. The Flash message file will show some error messages.

Hi ,

Thanks for your advice

Here are the files biab_plugin_crash_files ( I have not found files BBREsults.txt and BB Song.txt) , and the EventWiewer trace.


Before the error , I was able to generate about twenty generations of the same song in a row ( without playing it)


The WinDbg.txt file was made by attaching WinDbg to Reaper_Host64.exe process (but not in the same session as the files above)

When reaper locks up, in the Task Manager you can right click reaper.exe > Create Dump file
then zip it up and post in the reaper forum and they maybe able to tell you what's wrong.

You can try it in KV Element in Reaper
load element as a vst3 plugin then drag and drop the BBPlugin into it, hook the in/out up then click the EXT top left to sync it.

You can try Band In A Box Track Injector for Reaper

Hi ,


I can not create a dump file using the Task manager as the process does not lock but die

The Windows Event Viewer mentions several files but I can not find them
found errors are : 0xc0000374 , 0xc000041d , 0xc0000005 in modules "ntdll.dll" or "Band-in-a-Box DAW VST Plugin.dll"

This issue is very random , sometimes the crash happens at the first generation or after a few generations , but not always

BTW , I have the same issue with another daw (VstHost)


Thanks for your help anyway

Gegu,

Thanks for collecting all those files.

The plugins depend on the main Band-in-a-Box program to regenerate tracks. The bbw4_64.exe app you mentioned runs in the background as needed to provide a communication path between the plugin and the Band-in-a-Box program.

Again, thanks for your assistance.

Hi ,

FWIW , here is the procmon64 trace of reaper_host64.exe and bbw* processes from beginning of song generation to the crash : procmon64_logfile

using the build 4.5.33 of the VST2 plugin in Reaper 6.57 , driver asio RME Babyface Pro @ 44.1 Khz / 24 bits


No trace of a Band In A Box program , only the backend
but it seems that the size of bbw64.exe and bbw4_64.exe are similar ( 54946 kb vs 54981 kb) ?

There are several WerFault.exe process near the end

Also , I have tried to do a test with "dummy" audio driver in Reaper with the same issue.

Hi ,


It seems that unckecking "sync" during song generation does the trick (both in Reaper and VstHost)

If checked , error happens again

(Why ? ...)

Oh, the sync button. Why didn't you mention that earlier. I think you have reinvented the wheel.
I have not seen that problem in a long time. See my setup.

Hi ,

The sync button I am talking about is on the GUI biab_vst_sync

It is not evident why it has an influence during song generation , but I am affirmative on this.

My point gegu was this is unforturnately old news to many of us. I set my configuration to avoid this trap. You ask why? Because even well into its 3rd year this application is a bit of a work in progress. It can work fine and do what nothing else can do, but you have to know what not to do.

Hi ,

The workaround (I think I have found) is not too restrictive, I hope it can be useful for others.

But of course it would be better if the cause is solved


Thanks for your help and advice

The somewhat glib response points to a glaring issue with BIAB..."old hands" find & share solutions and the program isn't modified to resolve them as there's insufficient "call" to do so.

Newer users are left with the task of problem identification & solution finding or asking for help in the forum as the search engine for such issues is, at best, hopeless.

If the wheel isn't known it will, eventually, be (re)invented.

Thank you for the feedback gegu! As far as I am aware, there has never been an issue regarding the sync button causing a crash while generating, so this is not old news to me.

In order to help determine the cause of the crash, I will need you to provide me with the following files:
1. C:\Users\Public\Ticket\BBPluginDebug.txt
2. bb\BBPlugin\SavedTracks\BBInput.txt
3. bb\BBPlugin\SavedTracks\BBOutput.txt
4. bb\BBPlugin\SavedTracks\BBSong.txt

*Note that files 2, 3, and 4 require the presence of this text file: "bb\BBPlugin\PreserveAllFiles.txt". All of the files should be acquired immediately after the crash.

Could you also provide me with a saved song file (.sgu) as well as the exact steps you took to reproduce this crash? This should include details like which style/other tracks are loaded and any other information that may affect the way the song is generated.

If you have a screen recording program (like OBS which is free), it would be great if you could share a video of your screen leading up to a crash. This is often the easiest way for me to determine what the cause of the crash is.

You can upload all this information here or email me directly at aguy@pgmusic.com. I will do everything I can to help you resolve this issue!

Hi ,

Here is the video recording of "follow that cab" generation with "sync" checked, using vsthost64 daw and the VST2 plugin (VST3 plugin , reaper daw crash too) :

vsthost64_biab_vst2.mp4

Sometimes the crash happens at first or after a few generations , whatever the song is


As I said , having "sync" unckecked during the generation helps a lot , but I have had a few crash even when doing nothing

As for the files you asked for , I have already given links in my former posts
