Hello
Made some re-arrangements with my VST-modules and finally HalionOne couldn’t locate anymore the GM set and GM drum contents.
I tried to find out, where these files should be located on the HD, but I failed.
De-installed the HalionOne and installed it once more. Same result!
The GM set and drums are displayed in the HalionOne soundbank view, but as soon I click on one sound, the failure message appears and it is not loaded 
Any ideas?
Where are for instance the *.vstpreset - GM sounds located on the HD?
I made a search, but just found the presets for the additional sound pack, located in the …vst3/steinberg media technology/
Any help is very much appreciated.
Cheers
