Keyboard plays in older C 8.5, C9.5 but not Cubase v10x

Hi all,

I recently attempted to use my Yamaha PSR975 Workstation as my MIDI controller for the 1st time (since upgrading to Cubase 10 Pro) and discovered a problem. My Halion Sonic SE is not responding to my keyboard…NO SOUND (and no keystrokes indicated)!

The obvious causes (cables, KB settings, etc) don’t seem to exist as this same KB works perfectly when I bring up my Cubase Pro 9.5 or 8.5! To add more confusion to the problem, my M-audio Keyboard controller works fine in all 3 versions, 8.5, 9.5, & 10! That tells me my Cubase 10’s MIDI is working. But why not my workstation KB? Anyone have any ideas I might check? I’m at my wit’s end. :open_mouth:
