6.5.6 Locking
The locking mechanism allows the user to prevent changes to a
whole preset or a part of a preset. The locking interface is divided
in DSP module(s) and macro processing (refer to Section 5.12.4
on page 14 for further information on the logical data section).
Every module needs to be locked separately; the lock status is
preserved with the import/export from/to le and copy/paste
operations. In order to lock/unlock an entire module or parts of
a module:
