How to load VST plug-ins using Vst

Start with an empty Vst transform:

Double-click on the transform. This will bring up a dialog box which you will use to select the actual VST plug-in you want to load.

Once a VST plug-in is loaded, the Vst transform will be reconfigured to include inlets and outlets for the audio channels of the plug-in, as well as inlets for the automation parameters (unless the paramInlets option is set to false).

In addition, the UI panel of the VST plug-in will be displayed in a separate window. This window can be used to change parameters and manipulate the plug-in similar to any other VST application. If the window is dismissed, it can be re-opened by double-clicking on the Vst transform.

Saving VST configurations

The state of your VST plug-in will be saved when you save the enclosing OSW patch.

Installation Notes

If you have already read this far, you probably already have you Vst external installed, but in case you haven't:

1. Copy the file Vst.osx to the "externals" subdirectory of your OSW installation (by default, this is "C:\Program Files\Open Sound World").
2. Copy the file Vst.html and the Vst_files folder to the "html" subdirectory of your OSW installation.
3. That's it. Have fun!
