weird MIDI lag

[sonicapg]

hi all

My system is Quad core Phenom with 16GBs RAM ,SSD system drive ,windows 8.1 ,PT 8.05 LE and DIGI 002 CONSOLE Hardware.

System also has an E-mu 1212m ,wichs feautures MID IN/OUTS and a Edirol uax midi interface thats USB .

there is a Roland Fantom S connected to digi's 002 MIDI IN, and i have some midi devices connected to Digi's 002 MIDI OUT ,
Digi omidi out --->Alesis QSR (M through) --->Proteus 2k(M through) --->(M through)Audity 2k
Pt runs okay , had no problems so far ,but much to my suprise I have MIDI Lag when playing Alesis QSR wich is the First device on this midi chain.

I can see the MIDI IN indicator on Digi console blinking when i don't play it

So is it the midi activity "trasmitted" by Fantom screwing midi ? is it PT doesn't like "other" MIDI devices ? i already tried to filter MIDI information received by d 002 midi in ,i also removed devices from Hardware setup
Fantom S is being set midi I/O from "Hardware" dialog.

help if you can
