EXS 24 Logic Sampler Users Group

I know it's a little OT, but i figured exs users would be a bit more 
keyed in to midi issues.
Can anybody offer up any suggestions?
 my midi in LAMP  has been getting worse and worse it is practically 
unusable at this point

LAMP 4.81, G4 466, stealth port, MTP AV. macos 9.2.1

.
I replaced the battery and completely reloaded all my mtp internal setups. 
mtp works perfectly in all free midi applications and my live setup 
(directly cabled-i.e midi channel 14 only goes to 1 output, 1 synth) 
works perfectly. 
In logic my vst instruments work great.
absolutely perfect.

It is when I try and output from logic back out to my midi units.
I'm getting random patch changes and stuck notes and just tons of 
garbage really.

tried turning clock on and off.
tried blocking mtc output in logic and using event filters on the MTP
tried running mtp at fast speed (didn't work) and 1mhz
replaced a bunch of my midi instruments.

I notice that the behavior of "search for mtp"  and "mtp cable mode" 
checkboxes is a little erratic too.

Any ideas what I'm missing here, or are the rumors about a conspiracy to 
stop supporting anything except  unitor true?
