You will need to check with your regional Yamaha distributor. There is no official Yamaha Dust Cover or Case/Bag that I know of currently for the S70 XS, but from time to time Yamaha does create promotional Synthesizer Bags... so check with your Yamaha distributor for your particular part of the world. Things like case/bags, etc., can be made available regionally by the local Yamaha distributor. Your mileage will vary.

That said, there are certainly case companies that make cases for all the major keyboard products, and there are certainly dust covers that are made to fit 76 note keyboards. Check with your local music dealer.

Okey. I understand.
