Casio CTK- 720 as midi set up in PT Express

Hi I am trying to get my casio CTK-720 midi keyboard to work in PT Express which I have just got. it worked in an old PT LE version.



It is connected via a USB cable to my laptop.

I have MBox 3G connected.

When I try to run it as a midi track I can hear it through the headphones & record but it won't let me put any inserts in- the inserts are blanks.

I have tried using it as an instrument track but can't get it to record anything.

I have updated the driver, which shows as casio keyboard on my drivers in control panel.



I don't really know how to set the keyboard up in PT. Avid Customer Assists suggested I speak to Casio but presumably I am missing something in PT Express to use it properly?



Anyone got any ideas? I have read other posts & tried those suggestions but with no luck.



i am using PT Express 10.3.4

on a HP intel 5 CPU 2.67Ghz laptop

4GB RAM

500GB HD

Running Windows 7 64bit, SP1



Thanks

Christian
