Vortex Sound Research

I've used my Keystation and Deepmind together in the past with no issues. I haven't used the Deepmind in about a year, but have been using the Keystation with my PC through USB. I'm currently unable to control the Deepmind with MIDI input from the Keystation, although I am getting audio output from a couple of patches automatically. A high note, sounds like an E6. I've tried resetting the Deepmind's global settings, as well as changing between the Keystation's MIDI Out modes. Anything else come to mind that I could try? Thanks!
