--- Comment #3 from Karmo karmo.rosental@gmail.com --- Installing Guitar Rig 5 Player installs also Guitar Rig 5.dll into "~/.wine/drive_c/Program Files/Native Instruments/VSTPlugins 32 bit" directory. This DLL can be loaded as FX plugin in program like LMMS. LMMS supports loading Windows VST DLLs (both instruments and effects) through Wine.
Back trace when loading VST plugin happens only in Windows XP mode. It works in Windows 7 mode. But I have to use Windows XP mode as other plugins work only in that mode.
