Amelie Scott DesignsEdge Quilting on Your Embroidery Machine Expansion Pack 7 Pattern

What machines does this work with?

What's the difference in the expansion xs? is the jnfo in the book the same and the cd has different designs on it?

are these on a USB stick?

My machine only does up to 4x4 designs, since its a brother se4000 and does some resizing will this work with my machine?
