While we don't yet have a dedicated case for the SynthStorm Deluge, one of the cases in our PULSE line may be a good fit!
The dimensions we have on hand for the SynthStorm Deluge are: (12 x 8.2 x 1.8 inches). If that aligns with what you have, we would recommend looking at the PULSE CASE FOR THE ELEKTRON OCTATRACK: (14 x 9 x 2.5) inches.
