Lost blue Korg synthesizer in a soft case with stickers at Danville Park.

I misplaced my blue Korg synthesizer at the Danville park while I was setting up for an outdoor jam session with friends. I remember having it on the bench, but when I returned moments later, it was gone. It's in a soft case with a few stickers on it. I really want to find it as it holds a lot of sentimental value for me.
