Lost black Novation Launchkey MK2 keyboard controller left on a bench near Lakeshore Public School park in Muskegon.

I accidentally left my black Novation Launchkey MK2 keyboard controller on a bench in the park near the Lakeshore Public School in Muskegon. I was there for a music workshop, and when I realized I had left it behind, it was already late evening. I would really love to get it back if someone has found it.
