please post your:
* OS (+service-pack-ver)
* lmms vers
* hardware specification (ram & soundcard is the most imortant)
* lmms sound device chosen
* if any -screenshots of error
* if relevant, demo mmp
* perhaps a sound-file

But the conclusion may still be that 4 Tune simply doesn't play well with LMMS and so isn't compatible. oh yes, several others does the same, some very high end like karikatune, and its something being looked at Always make sure that: https://lmms.io/documentation/Working_with_VSTs#VST_related_prob...

Just given it a try and 4 Tune does the same for me with the VST .dll in my normal VST folder. @slipstick - do i understand you correctly? You ALSO see this dll disappear, if you open a saved project? @Cobalt Did you upgrade? -But if slipstick has the same issue, then its the dll that not compatibl...

maybe i know the reason, but not sure Sure you make the correct choice on the first selection form? There is a somewhat weird workflow in the export dialogs (to be changed btw) You actually have to make the choice twice first here: https://scontent-arn2-1.xx.fbcdn.net/hphotos-xaf1/v/t1.0-9/11692663_...

The breakdown would indicate that the dll cant be used by lmms -:/ -32x ASIO does work, but will course bsod if it crashes!!

Latency can be set on the 'General Setting Tab' in 'Settings'
Mine is 145 ms , btw

I'm using Windows 9, LMMS vers. 1.0.2. Thats the first thing to change Here https://lmms.io/download/#windows you find links to the much more stable and feature rich 1.1.3 Make sure you get the correct version! DO remove (UN-install) old version before you re-install !! -But backup your own stuff f...

OH! you got it Then you do like this Close lmms!! In the same folder you have your lmms.exe, ( lmms-install-folder ) find the dll named libportaudio-2.dll Rename tis dll to something like.. libportaudio-2_ORRR.dll Unpack your asio4all64.dll copy that dll into the lmms-install-folder rename that dll ...

Which of the dll-links did you follow. I believe there are several, and only some works ..somewhat works :/
If you are on windows, the SDL will give best stabillity.
but
afaik there is no 64x version of asio4all (?)
Please chime in, if anyone knows any!

This behavior is with one specific VST -right?
You cant reproduce the problem with any of these
https://lmms.io/documentation/Tested_VSTs
-right
Please post:
* OS (+service-pack-ver)
* lmms vers
* if any -screenshots of error
* names and best download links of the failing vst's

No reason to apologize, it looks like there could be a bug here, so thanks for your report!
One thing i can tell you, is that Beat&bass-editor notes moved in piano-roll, will appear as if the do not exists in B&B-editor, but they will replay!
This is propl. fixed next release
