I just tried The Cool Piano and no dice. That one actually takes quite a bit longer to load, but still no sound. It’s very strange that only his samples wouldn’t sound under macOS High Sierra. It makes no sense. I’ve opened up his .dspreset files in an editor and tried to compare to other user’s samples that are working and I can’t really see anything different, aside from spacing. I’ve also tried just loading the .dspreset and also compressing the folder to a .dslibrary extension. No difference. More than anything, I just want to know why this is happening. I have been in touch with David Hilowitz about other DS issues pertaining to AAX and Pro Tools, which is now sorted, but he never responded when I asked about my issue with Christian’s samples.
