Auditor is a VST host designed for making A/B comparisons with VST plugins. You can load up to four VST plugins at a time, then easily switch between them using the A/B/C/D buttons on the toolbar. To edit the VST's parameters, you can either display the VST's own editor, or use Auditor's default editor. Switch between the VST's programs using the selector on its rack panel. Either send MIDI data from an external MIDI controller or use the on-screen keyboard.

The above screen shot shows three VSTs loaded into the Auditor rack on the left, with the Editor of the "A" plugin displayed on the top right, with the on-screen keyboard below it.

For 32-bit Windows, you need to have .NET 4.0 installed to run it. The user interface is written in C# (Auditor.exe) and the engine is written in C++ (AuditorB.dll). As with all Transonic software, this is open source.

Simple, and does what it says. No frills.. I dunno if it's even using my ASIO driver! BUT. it sure does what it says. I put it on my Desktop. Very quick and dirty. You can't record the output from this software. It don't record midi, but what it does is let you try out a VST quickly and see what it sounds like, rather than fire up your DAW. I like this little program a lot. I tried a few others, and like this one better. Very quick setup, and now you can check out your VST you just downloaded. Thank you for making this available, my hat's off.
