OK, I figured it out. In order to get sound from Elektron Overbridge into the DAW (Cakewalk) make sure that the sampling rate setting in your ASIO driver configuration panel, the sampling rate setting in the "Elektron Overbridge (in my case, or Digitakt, etc.) Control Panel" standalone app (see gear icon in top right to change setting), and the driver sample rate setting in Cakewalk ALL MATCH . . . I have it set to 256 in all 3 places and now I get audio in Cakewalk from my Digitone via Overbridge.
In Cakewalk I simply create an Instrument track (works with split as well, of course). The input is the midi Omni for the Digitone device, and output is your audio interface or Master Bus, or whatever you typically do.
Keep your input/output drivers in the screenshot above set to your normal ASIO drivers for your interface, and leave all the Elektron stuff unchecked.
