In that view it looks good. But not in my view in Window > Midi Monitor.
As said Note off can be a Note off message or velocity=0 Otherwise the note keeps playing.
Below a part of my result. The velocity=1 is causing problems. I think it is a bug.
Opus has no problem, but Kontakt does.

198 7276 1 98 2D 00 Note On ($9x) 9 Pitch = A 3 Velocity = 0
199 7276 1 98 31 00 Note On ($9x) 9 Pitch = Db 4 Velocity = 0
200 7276 1 98 34 00 Note On ($9x) 9 Pitch = E 4 Velocity = 0
201 7276 1 98 37 00 Note On ($9x) 9 Pitch = G 4 Velocity = 0
202 7276 1 98 26 01 Note On ($9x) 9 Pitch = D 3 Velocity = 1
203 7276 1 98 2A 01 Note On ($9x) 9 Pitch = Gb 3 Velocity = 1
204 7276 1 98 2D 01 Note On ($9x) 9 Pitch = A 3 Velocity = 1
205 7276 1 98 30 01 Note On ($9x) 9 Pitch = C 4 Velocity = 1

I have found a workaround it in Reaper, so I can move on.
In Reaper select all notes > Note properties > Off Velocity was blank, so I add 0 or 1 (or any value) and my problem is solved and I can continue with some extra work.
So not marking this thread as solved.
