no midi messages??

[DeW-R2004]

Here's my midi setup in cubase SX 1.02:

Tyros
Supernova 2
SW1000xg

M-audio2x2 usb

It's quite werid, i'm not even sure how this has happened-

The tyros is coming through channels "in 2x2 A" to "2x2 A out"
The Sw1000xg is coming through "in 2x2 A" to "SW1000xgsynth1"
And the Snova was coming through "in 2X2 B" to "SW1000out"

All was working perfectly, but suddenly one day I there were no messages being sent to the Snova? When i play on the channel, it shows messages on both the in and out channels, but doesn't record anything? I thought my Snova might be broken, so I just hooked it up to my tyros. It seemed to work fine.
I then thought it might be the usb 2x2, so I tried my tyros with both 2x2 A channels and B channels, but it worked ok too?

Anyone got any idea what's going on?

cheers

Sorry I can't help you with your problem, but I would recommend that you upgrade to v1.06 as there are a huge number of fixes for bugs between 1.02 and 1.06. It might not help you here, but it could save you some trouble with something else later down the road.
