With four signal paths per preset, the ability to SELECT an entire signal path as as single unit and to be able to copy and paste it into an empty signal path in another preset. Maybe it can already do this. Don’t know why I can’t get an answer from anyone whether it can do this or why I seem to be the only person on planet earth that wants this, as it was the primary reason I returned the Helix a couple years ago.
I you’re like me you create some presets that probably only require one signal path anyway for commonly used go-to sounds. Since you don’t have spillover and gapless switching, if you want instant access to this sound in a few of your songs, you must recreate this entire signal path into every new song-specific preset you create that requires it. Without the ability to copy and paste whole signal paths as a unit, you would need to copy/paste/save each effect block your go-to sound requires, going back and forth between your go to preset and the new song specific preset you are creating over and over again.
