I'm referring to the fact that, when you change the patch, the Helix doesn't mantain the spillover of the delay (and reverbs).
So, for example, the repetitions of the delay disappear as soon as you change the patch.
I can understand that for many people this is not a big issue, but, for my playing style, it is. For example in more than one song I pass, without a pause, from a quite wet lead sound to a very simple clean. This passage, without spillover is not that great. And I can't solve with footswitch mode because one of the reason I love multifx is that I don't need to tip-tap thorught switches and, once again, for my sounds, I should activate and deactivate 4-5 pedals every time at the same time... no way! :)
Neighter A/B mode is a big deal because I have at least 3 (sometimes also 4) sound for each song.
I'm confident that the guys at line6 will found a solution for this issue.
I can see a great work and passion for the new Helix and it's quite clear to me that their intention was and still is to make the best pedalboard possibile and to listen to the customers feedback very carefully.
