I suspect PreSonus will release Presence XT's editor extension in the near future. I hope it's integrated in Presence XT itself, so we can build our soundsets with drag and drop from Studio One. PreSonus and Bitwig co-developed a native format Bitwig's Sampler and Presence XT both can use. In Bitwig it's still limited at this time, but the format itself is promising, especially when more developers start to adopt it.
