Mario,

I checked your problem on my 9000PRO V2.02.

The MasterEQ Parameter Lock is working on my board without any problems.

Little bit more complex is the Split Point issue. Basically there are three split points since OS Version 2 for the PRO (Acmp, Left and R3). The setting for the Left Split Point can be locked by the Parameter Lock function, that works. Unfortunately the other ones are changing between registrations also if Parameter Lock is set.

Havn't checked the other Parameter Lock options.

Regards
Ulrich
