I originally posted this on the BIAB forum b/c I thought I was having the problem on both BIAB and RB platforms, but now I see it's only in RB.
When I go to select my synths, both on the MIDI devices dialog box as well as attempting to set a midi track to Coyote/Forte (I have both), these 2 don't appear as options...yet they did appear up until very recently.
I've re-installed Forte, I've rebooted both RB and Windows--no change.
I'm on the latest version of RB, and Win10.
Noel suggested that I check the MIDI device/Default DXi/VSTi Synth box, but, again, neither Coyote nor Forte appears any longer.
Any other suggestions?

Thanks!
