Nektar P6: the same event midi is recorded triplicate

Hello guys!

The June 16, 2015, I bought a Panorama P6 in Thomann. I have connected to a PC (Windows 7, Cubase 5).
When I play a note on Panorama P6 the same event midi is recorded triplicate (overlap) on Cubase 5. I have followed the Nektar instructions (http://www.nektartech.com/s.nl/ctype.KB/it.I/id.1717/KB.666/.f) and the Steinberg instructions (https://www.steinberg.net/nc/en/support/knowledgebase_new/show_details/kb_show/midi-issues-on-windows.html) but have not solved the problem.
The behavior is the same if I replace the computer for a laptop. But if I change the Panorama P6 for a Roland PCR 30, all it’s Ok!

Thomann tell me it is a defect of the keyboard an that I have to send for repair. I think it must be a problem software. Now, I’m waiting an answer from Nektar.
I’ll be very grateful if anyone can help me.
Regards.

My Equipment:
Personal Computer, i7, 8 Gb RAM, O.S. Windows 7 (64 bits), Cubase 5 (32 bits)
Laptop: i7, 4 Gb RAM, O.S. Windows 7 (64 bits), Cubase 5 (32 bits).
Waiting for your answer to solve this issue.

Hello,
I’ve reinstalled nektar panorama p6 driver and update again and all it’s Ok
Regards.
