For diagnostics (i.e., to check midi data flow, what data is being sent from my gear), I use an old stand-by: Midi-Ox. There are others; its just that I know how to do what I want with Midi-Ox. I have foun d that it works just fine under Win 10, even though I don't think it was updated in a while.
I have also used midi-ox to receive and send sysex commands. I don't see why Control Change commands wouldn't work.
If you are using the CZ-101 as a sound module, maybe the device that sends it notes can also send a local off command. That way you won't need a separate computer utility.
Hope this helps.
