As far as I see it, there is no feature to remove all effects of a clip, a track, or the master at once. This would be particularly helpful, because loading a new plugin chain does not remove the previous effects. So, if you experiment with different plugin chains or if you loaded the wrong one accidentally, you have to remove all the effects manually, before you can load the next chain.
the blue arrow on the bottom of the master section does it .
And for clip or track effects?
I have created a preset labelled ‘No Inserts’ and load that.
