First of all, sorry for my bad english, then I have a problem with my MIDI configuration, I use two HDSP9652 card on Win 8.1 with cubase 7.5 64 bits and the MIDI ports on my card 1 are duplicated.
In cubase 7.5 I see the midi port  configuration as follow :

HDSP9652 Midi Port In 1
HDSP9652 Midi Port In 1
HDSP9652 Midi Port Out 1
HDSP9652 Midi Port Out 1
HDSP9652 Midi Port In 2
HDSP9652 Midi Port In 2
HDSP9652 Midi Port Out 2
HDSP9652 Midi Port Out 2
2-HDSP9652 Midi Port In 1
2-HDSP9652 Midi Port Out 1
2-HDSP9652 Midi Port In 2
2-HDSP9652 Midi Port Out 2

Wee can see that the card 1 midi port are duplicated, I had the same problem when I worked on win XP with cubase 5 (only when 2 HDSP9652 are connected; midi port aren't duplicated when I connect only one HDSP9652) but I just had to mask the duplicated port and the problem was solved.

But the problem with my new configuration (win 8.1, cubase 7.5) is that the midi port duplicated haven't got the same adress and sharing between the two cards :

For example, the duplicated HDSP9652 Midi Port Out 1 is linked with 2-HDSP9652 Midi Port Out 1, so they have the same adress but a different name, conversely, the duplicated port and their original port have the same name but different adress...

I tried reinstalling card in a different order, I use the lastest driver, my card are up to date (rev 118), I can't solve my problem.

Why the card 1 midi port are duplicated in a multicard configuration ?
How can I fix it ?
Can I rename the port in window or change their adress ?
