While we don't yet have a dedicated case for the Behringer Odyssey, one of the cases in our SUSTAIN line may be a good fit!
The dimensions we have on hand for the Behringer Odyssey are: (23.19 x 16.1 x 5.24) inches. If that aligns with what you have, we would recommend looking at the SUSTAIN Case for the Sequential Pro 3: (29 x 17 x 6) inches.
