Does Musecore support multi-layered velocity soundfont?

Using Polyphony, I created a soundfont with two layered velocities. In Polyphony preset, I set a district velocity range for each layer ("instrument"). However, in Musecore 3, the lower velocity layer is ignored. When I change the velocity of notes to within the lower range the first, upper velocity layer (instrument) still plays. What could I be doing wrong?

Does Musecore 3 support multi-layered soundfonts (sf3, sfz, etc)?

Thanks, Sam
