Hi, yes channel strips are a quick way. I have found an interim work around but it is long winded.
1. In Finder locate the Plugins patch folder, for example for Omnisphere go to User/Library/Application Support/Spectrasonics/STEAM/Omnisphere/Settings Library/Patches/User.
2 Make a duplicate of an existing patch.
3 Rename that copy to the name that you want to save the new patch as.
4 Now go to Logic and select the Plugin. Now when you go to save the patch, instead of having to type a name, you can select the renamed patch. You will be asked if you want to replace the patch, say yes.
Channel strips are a lot quicker, but if you want you patches in their correct homes, this is a way to do it.
