The point is that sfz files require the accompanying .wav files. They aren't any good by themselves.

I've used the non+ version for years with .sf2 files which are self-contained, so this won't be an issue for me. I don't even have any .sfz files since they are pretty cumbersome because they require the many .wav files that go with the pointer .sfz file.

I'm guessing most people that have been using sfz, the non+ version, have mostly soundfont files. sfz+ will allow them to create their own sample sets.

I look forward to the multi-outs for the very nice nskit drumkits from long ago. sfz only allowed stereo outs, now dynamics processing on multi-outs - nice!
