I got the latency issue worked out on native some what it's better than it was but still have to turn off the green Z to switch or tweak the presets in native. I didn't have this problem when I loaded the native trial in S1-3 back when line 6 launched native. I'm pretty sure it's got somthing to do with a update in Windows 10 that corrupted the files from line 6 website that I had to deal with when I bought native,I had to turn off some search filters in Windows to allow native to load right, might have to uninstall and reinstall native, if PreSonus has fixed the issues in S1-3 already. When I had the native trial PreSonus didn't have the low latency Z monitoring yet, I'll have to open a ticket with PreSonus support too I suppose. I have the helix rack too and found it best to record guitar with the rack as interface through the multi outs, records dry track while your monitoring full fx from a stereo track then I switch back to using Studiolive AI as interface then use native as a plugin to tweak settings as I monitor dry track, no need for the green Z for monitoring recorded dry tracks. Thanks for the info Doug6string!
