linvst doenst close after closing host

[osxmidi]

The host is supposed to send an EffectClose message to vst's (including LinVst) when a plugin is removed or the host shuts down.

LinVst can't close without the EffectClose message being sent by the host because LinVst is a wrapper and needs to close down some system things and clean up a few things so that it exits in a graceful way whereas a native vst plugin might appear to close without an EffectClose being sent by the host but that is not ideal because various plugins might depend on the host sending EffectClose and do some cleaning up when an EffectClose is sent by the host.

I have seen Tracktion (version 4 I think) not send an EffectClose message due to a bug in their code.

I don't know what Mixbus is doing but maybe LinVst isn't getting an EffectClose for some reason or it could be due to something else.

Mixbus 4.3 will do the same as Ardour 5.x. I am also using linVST with Mixbus 4.x and have never seen any linvst processes hang after a clean shutdown of Mixbus - only on the host crashing.

Indeed I dont think its the host, because the same plugins dont hang wineserver with the other vst wrapper i use. However with the other wrapper I cannot overcome the wine issue with the embedded window.
So its probably something on my system that causes this issue?

Could be.

I havn't heard of any MixBus or Ardour LinVst shutdown problems.

Any hints on what or where to look for?

Wine would be first.

Possible overrides doing something.

Try deleting the wine prefix (default is ~/.wine) and rebuilding it by running winecfg.
