Hi Domenico.

Thanks a million for all your help. Without your advice I wouldn't have been able to track down the cause of the problem.

The problem wasn't the Meidastation at all. It was the Ketron SD2. It doesn't like the length of my midi cables (15ft). I had one 6ft cable in my spares case and when I tried that it worked.

I tested my 15ft cables between the Mediastation and OASYS, no problems at all.

Try it with the SD2, forget it. No sound. Connect a 6ft cable and it works perfectly. I must complain to AJ now

Regards
James
