I tried all and checked the manuals. Actually, nothing is though. You just switch the button to midi option on keyboard. I tried not only Noteworthy but also other softwares, in case there might be a problem on software. One thing I dont understand that is how possible an old midi connection is incompatible with a today's usb midi cable. I can expect a problem if I had used an old usb midi cable with newer device. However this is opposite.
I have the same problem with my Casiotone CT 660. I can see my midi "Viewcon" on vista settings and software midi options, however when I strike the keys, the software can't respond that. Whenever I play the note on software then I can hear the sound from my keyboard. I tried all option. I think my keyboard is incompatible with sth, software, vista or cables, I dont know.
If anybody encountered same problem and fixed it, please tell me.
