My main point is a general one that, as far as I can tell, the high-quality samples available today of instruments (e.g., oboe, horn, violin, clarinet) that are difficult to make sound good/realistic are either not available on Linux or are not practical. Not available in the case of VST/VSTi samples; and not practical in the case of GIG samples (since, IME, linuxsampler has too many limitations to be practical) - plus with gigastudio discontinued the format will be obsolete in a few years, IMO. I'm not aware of any SFZ samples of such instruments that are high quality, but I could be wrong. (Sure there are VST samples available for Linux, but I don't think there are any of truly high quality [such as the Vienna Symphonic Library].)
I'm generalizing, due to lack of time to research this further at the moment, but I think my general impression is correct. If I'm wrong I'm happy to be corrected.
