I’m working on a wind instrument in HISE with multiple velocity layers. I want the mod wheel (CC1) to simulate breath/air pressure, so that the sound smoothly transitions between velocity layers depending on the wheel position.

Right now, CC1 only controls volume (gain), but it doesn’t switch or blend between groups/layers. I couldn’t find a clear X-fade or controller-based group selection option in my version.

How can I make CC1 control crossfading between velocity layers/groups?

Thanks!
