this strange bug affect only ROOMWORKS, but not ROOMWORKS SE, or other.
But it is better you check all the steinberg fx , factory preset.
1 load a stack, and ROOMWORKS ON INSERT
2 TRY LOAD A FACTORY PRESET
3 the name of the preset appear, but no change is made of any parameters
4 try to load a user preset (or save one and re-load)
5 user preset works as expected
ROOMWORKS SE , instead works fine, and standard compressor too… i never tried all steinberg fx.
