QuoteHow to update all effect presets?
To take maximum advantage of the new integrated effect selection page, you should exchange all legacy factory presets for the new, updated set.
Thankfully, the latest Rig Manager revision supports PROFILER OS 7.0 by introducing the ability to administer presets! So, please connect your PROFILER to Rig Manager, select your PROFILER under "All Presets" in the left column, and delete all presets except the ones you have created and intend to keep. Wait until Rig Manager and PROFILER have synchronized, and all selected presets will now be deleted.
At this point, you could choose to use Rig Manager to import the entire set of new presets, or select elements of it, from the Preset Pack “Factory Presets 7.0”. There is, however, an even a simpler method if you want to import the
complete set: Press the SYSTEM button of your PROFILER and select "Factory Presets" in System Settings. The complete set of updated presets will be now be imported automatically.
I take it from this, there are performance advantages to having a "clear out"?
However, i can not find "factory presets" in the "system" button of my KPA so not ready to do this yet.
Can anyone who has done this please share their experience from a user point of view, just so i know my attempt will worthwhile. thanks
