Midi in doesn't work!

[xebb]

Hello everybody, here's Xebb from Italy.

My english is not perfect but i hope you could understand me anyhow.

I used to connect my Virus TI Desktop to a master keyboard via midi, with no troubles. 2 weeks ago Virus' midi-in quitted working, for unknown reasons. I connected the Virus via usb to a Macbook, with Logic 8, and the sounds came out from the Mac, not from the Virus..

(the audio outputs work because i tried the demo song with no problems)

Today i tried Midi Patchbay software, and altough the Mac recognize both the master keyboard and the Virus, no sound comes out from the TI.

My question is: what's the problem??

Every help is appreciated, thank you very much and compliments for the forum!
