The only information I found on how this could work in an emulti is here:
For now, I’m concentrating on SFZs and have spent the last few days testing what works and how… and why some things don’t work… very time-consuming and frustrating, but I’m making progress. Unfortunately, Sample Robot doesn’t currently support round robin, so you have no choice but to add it to the SFZ file afterward. Fortunately, round robin also works in headers, so it’s quite quick to implement.
My main goal is to transform what Sample Robot spits out into a usable resource for Tonverk sounds with as little coding effort as possible… including round robin, continuous looping during the release phase, crossfades as long as I like (need them), and so on. Converting this to an emulti seems like an unnecessary extra step to me at the moment.
