Andy I to have problems with the Korg MS-20 soft synth.  I did approach Korg but they came back with some rather weak and wet response.  I found the best thing to do when tweaking the MS-20 is to make a point of doing a Ctrl-S just before and just after.  I know it is not a fix but is stops other heartache.
 
I have not found any of the other Korg's soft synths M1, Wavestation, Polysix, Monopoly or LegacyCell to have these problems.

Thanks for confirming that Wookiee. Like you say, plenty of saves and live with the issue until it is sorted, if ever...

no problems here with ms-20 (x64 v1.3.0) in studio one (v3.3.1), have yet to test in sonar

If you are getting an actual crash please log a bug and post the CWBRN number here. There is detailed information on how to get a minidump here even if the system hangs or SONAR doesnt produce one for some reason when it crashes. This is most likely the plugin corrupting memory.

Thanks Noel.
 
In my case, Sonar is not creating a dump file. I have checked the minidumps folder and the last dump file is dated September 6th and will not be associated with my Korg MS-20 VSTi.
 
I've read the article "What if my software "hangs" and does not create a crash file?" but that takes me to yet another microsoft article and at that point I start to glaze over I'm afraid. I used to class myself as an "advanced" user but nowadays I really struggle.
 
For the amount of times that I use this synth I am prepared to work around the issue by saving regularly and opening the VSTi dialogue box as infrequently as possible.
 
kind regards

Unfortunately Noel when it does cause a crash what I have observed is it normally just goes Bang, SONAR dies without any clues. none of the normal errors or chance to capture anything.
