Okay, I was confused after reading the original post. At first I thought the evolution MK-249c was a third party computer keyboard (you know, a QWERTY keyboard used for typing and general computer input). I was wondering how a simple USB keyboard would cause PT9 to not work.

As I read more, I realized that he is referring to a MIDI keyboard (piano/synthesizer type). So since that is the problem it makes sense that PT9 may have problems with it if the driver is not compatible or the setting s don't match between the device and Protools settings.

You are probably better off contacting the manufacturer of the evolution MK-249c keyboard about an updated driver and/or the proper setting to use with PT9.
