PC-Soft recieves incorrect MIDI signaling

[cooperwishmaster]

I'm having an issue using a HSR 2.0 USB MIDI interface with Reason 4 (I have a KORG T2 and CASIO WK-3500, so I've ruled out both keyboards as the root of this issue).
When I play, for example, the notes: C4, D4, E5, .. A note, not necessarely the same notes I have played, A3, C3, ..., is triggered and the sound doesn't stop until I hit the Stop button or I hit the same note that is sounding on my keyboard.
I have searched as much as I could on google and in several forums, I sent an e-mail that was never answered to the store where I bought the cable, so I'm running out of ideas and this is driving me crazy, as I cannot even record 5 seconds of music without this happening.

I don't know if there's any software that can check the signaling of my interface, to see if everything is ok.

I'll appreciate any help you can give me.

Thanks in advanced.

Regards!
