Duplicate VST plugins loaded on macOS Mojave

Description:

When I click on a VST plug-in to load, Renoise sometimes will load two instances of the plugin instead of one.

Currently this happens with FabFilter, Soundtoys, IK Multimedia, Airwindows, and Toneboosters plugins. Once the plugins have been loaded and I delete one, If I click to load it again, only a single instance is loaded this time.

So far this is only with VST plugins since that’s what I use. Don’t know if this is true with AU plugins.

Steps to reproduce look like this:

  1. Launch Renoise
  2. Load a anyVST plugin

Expected results:

Only one plugin instance to load.

Actual results:

Two of the same instance of the plugin loads. i.e. FilterFreak then FilterFreak(1)
