After adding effects to a folder (in the Cakewalk Plug-in Manager), you can also specify default presets for each effect. Right-click an effect in the folder and choose Properties.
In the Item Properties dialog box, choose a preset from the Default Preset menu.
Click OK. Now when you insert the effect into a project, it will automatically default to the preset you selected. See pages 12 to 15 in SONAR X2 Power! for more information about customizing plug-in menus.
