sound garble when changing keys

[Retro Man]

I do see that these posts are almost two years old (it's now Aug 2016), but this is the first time I've visited the Hoster forum to see if others experience "warbling" when changing keys in Hoster. I understand that Hoster uses a digital key change technology, but KeyRite is also digital and seems to work just fine. For my own stuff, I sometimes change the key before importing a song into Hoster, but this is not feasible for on-the-fly key changes. Is it possible to use the same algorithm in Hoster as we have in KeyRite? Or are there other ways to eliminate warbling? Could it be sound-card dependent?
