really thankful for all the replies. But honestly, it's easy to insert a midi track and they all reappear. So far shortest way. Doesn't explain the issue though.
I midi files already are type one.... because they open with all tracks and leave about 4 when the "magic" is over. But I'll do the save also, just to see.
 
Funny, iirc, the this started "after" I tried Scooks TTS-1 thing. I'll try that agin and see if it undoes the wierdness
 

OK so I know what did it. Cannot believe it really.
 
Ok, so a while back, quite a while, I created a LENS of my own to always show the Synth Rack. Remember when they screwed with that?
Anyway, somewhere along the way, I guess about in the last 6 weeks or so I must have saved over my Synth Rack Lens (that was my name for it) and I guess their were only 4 midi tracks. Does that really make sense?
 
Because changing lens to "none", the issue goes away.
 
BTW, I do NOT use templates. I know after 2+ decades with CW you would think I would. 
 
Apoligize for the goose chase. But at least if something really weird happens we can mention check your lens's  :-)
 
Thanks again to all.

You know this is sooo funny, I was eating dinner and mulling over the problem when I thought about how lenses do weird things to projects sometimes. I was just going to see if that was it and I guess we both figured it out at the same time! 
 
I have this thing where Ièll open a second project and I guess the lens changes to a different view even though it still says advanced. To get my view back I have to click basic, then back to advanced, This is the times I thing I loose my tracks. 

Hey 
Pretty strange, Wish you would have though of it weeks ago... So, the only lens I have is the Synth racK one. 
 
You know I have been using CW the SAME way for so many years, I really need to explore. Like templates, which I never use is one example of many.
Thanks again
