Hi Arne,

Arne Scheffler:

Hi,
OK with a working input I was able to get VSTHost crashing. And it’s the same as with Mixcraft. It is calling the IEditController from the audio thread :

Thank you for uploading the stack trace; makes things easier for me.

indeed. Well, Dave Clark reported the issue to me; I’m looking into it. For future reference, I, Hermann Seib, author of VSTHost / SAVIHost, am registered as user “Arakula” here since quite some time; while I’m not a regular lurker, an incoming PM should be brought to my attention per eMail quite fast.
