Absolute and Relative Editing
When editing multiple samples, you can either change values absolutely for all the samples (ABS) or make relative changes (REL), depending on the setting of the corresponding button on the toolbar.
If you use absolute editing and you change a parameter from 50 % to 60 % for one sample, all other samples are also set to 60 %.
If you use relative editing and you change a parameter from 50 % to 60 % in one sample, another selected sample that was set to 70 % is set to 80 %.
Note
Relative changes can be made for all parameters that can be adjusted continuously. Changes of parameters that select one of multiple modes or switch between two states are always absolute.
