I use L (mono) XLR to desk, L (mono) jack to Catalyst (behind me), Headphones out (stereo) to keyboard player (he prefers that for his in ears). I get my own monitor mix (mono) from board, mixed with XLR out of Catalyst (own mini mixer for my in ears). Bassist and drummer get their in ear mixes from board too (mono). Vocalist has stage monitor (old school). Hope that helps. Basically, our FOH is mono. Never seen the point of stereo. Some of my Helix goes to board and out of PA in mono. The rest of my sound is from Catalyst, running the Helix into its power amp input (yes I have cabs active in my presets). We play small/medium bars and clubs. Hope this helps.

Possibly, but editing through HX Edit (which I prefer) rather than on the Helix itself will be broken. Also making backups through HX Edit. Good detective work. Looks like an unintended consequence?

Up to now I've been able to run HX Edit on High Sierra but now, HX Edit 3.8 says it requires MacOs 10.15 Sequioa, so users with High Sierra or Catalina are out of luck updating to Firmware 3.8 I can't see any mention of this in the release notes. Fortunately, I could quickly go back to my previous version of HX Edit from my Time Machine Backup. I think it would have been more polite if Line 6 had warned us older Mac users before we hit the buffers at full speed. At least HX Edit 3.7 is still available to download from the Line6 site, so there is that. By the way, when is the 'Hot Fix' for Apple Silicon chips coming? Surely it's been long enough since M1 chips arrived? My new M4 machine is now days away, so I will be stuck with being able to back up properly and not upgrade or vice versa.

Fender deluxe reverb. Add seasoning to taste, as in real life!

I'm having the same/similar problem. Snapshot 1 has a whammy pedal octave rise and snapshot 2 an octave drop. Both on EXP1. Last night's gig was 'fun' in that both had a rise. I can rectify this in HXEDIT but the benefit isn't saved on a power cycle. That's a blow. Return to 2.7.1 or wait for 2.8.1 and in the meantime change the setlist!?

All done, everything AOK, using OSX

Beyerdynamic DT150 250 Ohm working just fine.

I have a mid 2010 mac book pro. I've maxed the ram and put in a ssd. Easy to do yourself. Its like having a brand new machine.

As a newbie here running El Capitan 10.11.6, do I need the Mac Driver or is my OS playing nicely with my Helix in Class Compliant mode. In other words, at which OS update did Apple fix things? Anyone know for sure? Thanks.
