If I understand you correctly it should work if you
select a clip in the AM
load the relevant plugins on the selected Clip
select and copy the plugins in the Inspector using the Copy botton or Menu option
then select remaining Clips and paste the plugins using the “Paste to all selected clips” in the Inpector Menu
If you want to you can also load the plugins in the Master Section first, and then import them into Inspector using the Import Master Section Plugins button in the Inspector and then copy and paste as above.
Yes. WaveLab 10 added the option to paste a copied Clip FX chain to all selected clips which is nice.
So, after your first Clip FX is dialed in, you can select it, and then you can use the shortcut to “Invert Selection” so that all other clips are now selected. From here, you can use “Paste To Selected Clips” and now all the selected clips have the same plugin chain.
