New S8 user here. I’m unsure of how patches and performances relate. As I understand it, patches can have an upper and lower voice in dual or split mode. Do Performances use 2 of the patches in memory, thereby having four layers (2 for each patch)?

Thanks.

I think a patch is applied to either upper or lower voice. A Performance is both voices saved as they are (single, dual or split). You can see a Perf as one or two patches bundled together.
