Just purchased Samplitude Music Studio (2017) and most of my third-party VST plugins seemed to load with the exception of "Instruments: like Air Music Tech's LOOM II synth and Izotope's IRIS 2. I'm surprised that SMS2017 only provides for one plugin path option in the preferences, but I don't think that's the main issue. Does anyone have any suggestions on loading these third party 'instrument' plugings? Thanks Bart
