T46G - How to "lock" the line keys?

[tb303]

I have tried this and it "sort of" works....
I have set this in the MAC config:

Code:

linekey.1.type = 15
linekey.1.line = 1
linekey.1.value = 2
linekey.2.type = 15
linekey.2.line = 1
linekey.2.value = 2
linekey.3.type = 15
linekey.3.line = 1
linekey.3.value = 2

And set some DSS keys:
   
   

The result is:

   
   

As you can see, the 3 lines keys overwrite some of my BLF/Speedial keys when I select page 2.

This looks like unwanted behaviour. Can I fix this, or is this a software related issue?

Kind regards,

Michel
