VST External Scanner
When Turbo Play initially scans from your VST plugins (either via the VST Explorer or the Wizard), it calls its etxternal scanner, VSCAN32.EXE. (Because most VST instruments are currently 32 bit, Turbo Play x64 version also starts with VSCAN32.EXE).
This scanner performs the following:
- It loads each VST to be tested in a separated process. This ensures that, no matter how faulty the VST is, it will never touch Turbo Play or the external scanner.
- If the plugin is 64-bit, it calls VSCAN64.EXE to do the testing.
- It tests the VST if it can be loaded. If the VST cannot be loaded, it enables UAC Virtualization and tests it again. (For more on UAC Virtualization, see VST plugins).
- It optionally tests the VST under a sandboxed environement (that is, in a way that the VST has no write access to your hard disk).
The results are stored in the VST Explorer. VST External Scanner is the safest method you can test a VST plugin for its validity.
