Teenage Engineering OP-1 portable synthesizer

I lost my Teenage Engineering OP-1 portable synthesizer yesterday around 3pm. It's the orange body version with white keys, a tiny dent on the bottom edge, and a red sticker with my initials 'PK' on the back, plus a frayed orange strap I made myself. I last had it outside Music Exchange on Main Street in Springfield after a quick jam near Riverfront Park; I must have stepped away to tie my shoes and now it's gone. This thing is a reliable workhorse for gigs and practice, and it holds a lot of memories—it really means a lot to me. If found, I'd really appreciate getting it back.
