In RealBand there is a MIDI data filter that allows you to set various ranges and settings that may allow you to set settings so that everything is filtered from editing except the data included within the range you specify.


Access it Edit\Midi\Change Velocities

Check the Data Filter box to access the filter options

Not sure that will do what you want but is the best option I know of to make a batch adjustment of specific ranges.
