I also have the 18i20, and use it with S/PDIF when I'm playing through my Studio Monitors (vs PC212). I record with Scarlett as interface. Helix and Scarlett need to be at the same sample rate. Global Settings>Ins/Outs>Digital Output needs to be set to S/PDIF. Scarlett mixer needs to have the Input of the Output you're monitoring on set with S/PDIF enabled. Scarlett Clock Source needs to be set to Internal. That's probably the problem. You also need a proper digital cable, audio RCA won't get it. Here's a screenshot:

Just posted new files. Check out the added Looper functions.

I'm about to post a new improved version (128 presets + more stuff), so you might want to try the DL again later. Of course, if you've modded it to your own needs already, you might already be good. I'm having a ball with this chip!

The curse of "the unfamiliar sound guy who sucks". The way I see it, if the venue hires the sound guy, the club should have it's own PA. If the venue's PA and/or sound guy sucks, you either suck it up or don't play there again. If the venue requires you to let their guy use your system, you either suck it up, or don't play there again. If YOU'RE paying the sound guy, he does what you tell him to do. Period. If he doesn't do what you tell him to do, and you hire him again, it's on you. There's no amount of presets on your Helix or your XR18 that will cure the curse of "the unfamiliar sound guy who sucks".

I could't find a manual for it. If you know how to program it, and it can send Toggling CCs, you should be good.

Just got my UNO2 chip for my FCB1010. Here's my first configuration. I've tested it on my Floor and my HXS. Obviously it's best suited for a Rack, if you can't afford the Floor Controller. It has 19 Banks of 5 Presets on the lower row (FS 1-5). The upper row selects Setlists 1-4 on FS 6-9. FS 10 switches the FS functions to 5 Stomps (FS 1-5) and 4 Snapshots (FS 6-9). FS 10 switches back to Preset Mode. If you have an FCB1010 with the UNO2 chip, you know what to do with the file. Hope somebody with a Rack and an FCB1010/UNO2 tries it! I also have one configured for an AXE FX II/III if anybody wants it. EDIT: I've moved these files to here: https://fcb1010.groups.io/g/uno After you sign up, the files can be found in FILES/EJ's UNO2 Along with Helix and AXE FX there's files and instructions for Amplitube 4/5, Guitar Rig 4/5 and TH3/THU. I've left just the Helix file and instructions here. Hope this helps somebody. If you do try them or have comments, I'd LOVE to hear from you!

I mean to level the Helix Presets within the Helix, so that the output level is the same for all of the presets. I'm not really familiar with the XR18. If it has Input level meters you could use those, combined with a db meter (on your phone?) and your ears. Then you'd only have to set the Trim once, and FOH only has to adjust the Channel Volume as necessary for the song/room. Keep in mind that if you're using a clean boost for solos (I use a FS with MIN=0/MAX= +4db), you'd want to set the trim with the boost ON.

Lots of differing opinions on this. My 2 cents: Do your preset leveling on the Helix. Get your gain staging right so that you're not overloading anything in the signal chain. Be aware that Clean tones have more dynamic content than overdriven (compressed) tones, and will likely sound louder.. Then send a Unity signal (big knob disabled on those outs) to the XR18, and use the XR18 Channel Trim to get the strongest signal possible without hitting the red. The XR18 Channel Volume is then your final Output Volume Control, and should be set and forget if the Helix Presets have been properly leveled.

FWIW - I've used the Microsoft AV and CCleaner for years without problems, but everybody's systems and surfing habits differ, so YMMV.

You've set your default PC Preset to FRFR, same as the Factory FLAT STEREO. Set it to LF Flat, the same as the NEW PRESET default, and it'll all work as expected in all Helix Modes/Voicings. The ONLY time I can duplicate ANY of these problems is when the PC Preset is on anything other than LF Flat, and I try to change the Modes/Voicings from Helix. NO problems with HF Trim settings when changing the Modes/Voicings from Helix when the PC Preset is set to the LF Flat voicing. NO problems when using Helix Presets that use different Modes/Voicings when the PC Preset is set to LF Flat. My test PANAMA preset with the Exp Pedal set to CC#5 for quick testing proves it EVERY time! I duplicated that preset 5 times with different Snapshots set to different Modes/Voicings as defaults, no matter what Mode/Voicings are sent, no matter how many times I switch the Helix Presets, or switch the Snapshots within them, the HF Trim ONLY affects those Modes/Voicings that it's SUPPOSED to affect, turning it OFF/ON as expected for the Mode/Voicing, AS LONG AS THE PC PRESET IS SET TO LF FLAT! I don't know WHY it works that way, maybe it shouldn't, but it is what it is. There MAY be faulty PC212s out there, but mine is not one of them, and it's hard to believe (though not impossible) that you got two bad ones in a row. I'll certainly try your step by step instructions to try to duplicate the problem, in case I'm just not getting it, but I'm 99.999% sure it'll all come back to setting the PC Preset to LF Flat, or NOT changing the Modes/Voicings from Helix when using a PC Preset set to other than LF Flat.

And set your Input Level to INST in Global Settings>Ins/Outs..

Please post two presets that demonstrate this and I'll try it out. Since I never bother with the HF Trim in my usage, I've never noticed this, so it would be nice to be able to verify in case my use changes in the future. When this happens, what PC preset are you on?

I posted this over on the Powercab forum, but I'll post it again here for those who have a Powercab but don't follow that forum. In response to a discussion over on TGP: I did some more testing, this time using the PC Factory Presets. My "TEST" preset has 5 snapshots as described in my previous (EDITED) post. I assigned the Exp Pedal to CC#5 (HF Trim) to make testing easier. Using a NEW PRESET in Powercab as my default setting, the HF Trim has NO effect in Speaker mode, or in Flat/LF Flat or Flat/LF Raw. It ONLY affects Flat/FRFR Mode and USER IR Mode. And, being a GLOBAL setting, it stays the same in EVERY Helix Preset, AND in EVERY Powercab Preset, Factory or NEW. However, if you use a FACTORY PC PRESET, all bets are off. In the FLAT STEREO preset, HF Trim affects EVERY Snapshot. Using a SPEAKER PC Preset, it works the same as a NEW PRESET. Using a USER IR PC Preset, it works as in the PC FLAT STEREO Preset, affecting ALL Snapshots. Again, being a Global setting, it remains the same everywhere. Here's my preset if you want to try this out. Panama.hlx

FWIW - my old laptop is in my "office" (the DR) now, connected to my HX Stomp, the FCB 1010, a wah with VooDoo Labs PS, a mixer and a bookshelf speaker system. Got no ground loops.

Well, I hate to break your heart, as you seem happy to lay the blame on L6, BUT..... Before I had a single piece of L6 hardware, and before I had a laptop with a USB C port, I used most of the same USB devices with computer sims (Amplitube, Guitar Rig, etc) and had the same USB ground loop problem. It's a PITA, and I wish I had a "sure fix" for ya, but all I've got is how I fixed it in my current rig. Good Luck!

Do the Channels switch via MIDI, If not, no.

Bad news. Ideally ain't gonna get it, and a differently branded HD400 equivalent didn't work. My experience, FWIW - I have 8 (sometimes 9) USB devices connected to my laptop. Helix, Powercab, Audio Interface, External HD, and 4 (sometimes 5) MIDI controllers. Powered USB hub and USB C hub. Everything in one wall socket with quality EMI/RFI Surge suppresors. I switched ALL the connectors around. And around. MANY times. I bought the $50 USB isolator and tried it EVERYWHERE. IT MADE IT WORSE! Out of desperation I connected the Powered hub to the USB C hub. That fixed it! Go figure! Why? I have no clue. Would this work for you? Maybe........maybe not. Good Luck!

It would also be helpful, when you post the results of the steps that @codamedia suggested, that you also post your Helix preset. I'm sure that you're sure you've got it right, but trust me, we've seen that before.

Go to Page 10 of the owner's manual v3.0 Rev E. You might want to at least skim the rest of the manual too.

No and No. BUT - you can vote for these types of flexible routing options over on Ideascale, they've been requested more than once (search and vote for all). @waymda's suggestion sounds like it might work though.

That's a really good viewer. Here's another: https://dbagchee.github.io/helix-preset-viewer/

I'll attach my modded version. If it still doesn't work for you, recheck your MIDI settings in Globals. Maybe a factory reset is necessary, or even a complete reinstall of 3.01. Running out of ideas. It works for me! CLEAN AC15 FRIED.hlx

When you press the ROTARY switch, it DEACTIVATES the Rotary Block. Press FS2 to engage EXP2, then activate the block manually. Switch back and forth to make sure that both actions are occurring, then SAVE.
