Direct access to synths?

It seems as if I only have MIDI Mapper (does not exist in Vista) or VST/DirectX plugins? I have various synths such as Yamaha’s SYXG 50 , and also MIDI ports both hard and loopback, but these do not seem to show, except via the MIDI Mapper.

Any advice appreciated

S’OK. Settings/Preferences/MIDI Settings

Sorry. But rusty.
