Recently, the limited number of ‘Fibre Link Storage’ slots available on Windows application became a serious bottleneck for any windows daw written in C++. Each vst plugin uses a small number of the FLS slots, plugins from the same vendor shares library they use. But then once the number of the slots used in a process reached 128, it won’t be able to open any more dll files. Thus a plugin fails to initialize on the daw without any apparent reason.
Daw and plugin makers are aware of this problem and already started to update their products to use fewer slots possible, however you still see this problem in many cases. There are lots of reports related this on public forums.
I have built a simple plugin that shows the number of the FLS slots available. It will report the number when its GUI is opened, or when the update button is clicked. It uses 1 slot by itself.
