  1. Thanks. I need to look at the saved files and see which ones are in XML. Then maybe I'll do a factory reset and back that up for comparison.
  2. User Defaults are very useful, but, on balance, I think I use Favourites more often. And, because I was a n00b when I started playing with User Defaults, I'm wondering whether changing the defaults was wise in some situations. My question is: short of going through every amp, cab and effect, looking for set User Defaults, is there a better/cleverer way of identifying which ones have been altered? This might be using the Helix control panel, Helix Edit, or getting under the bonnet and looking at preset/setlist/bundle files on disk?
  3. I'm just about to start gigging again, for the first time since the 1980s(!) I have a Helix LT with loads of presets of different FX and amp combinations for our setlist. I've never had any trouble with it, but all of a sudden, I'm worried it will pack up on me. I could buy another one but it's the best part of a grand now. I could also buy something lower down the range, but I'm concerned that either there won't be enough footswitches and/or paths, and I'd need to make some preset/pedal compromises. So, hiring at short notice might be a useful backup. Does anyone in the UK have any useful pointers, please? I'm in Dorset.
  4. FYI Line 6 Support got back to me. Their recommended line of attack was to reinstall 3.15 using Updater 1.25 software, and do a factory reset. Sure enough, the problem went away. And when I restored my full backup, it was still working as designed. I appreciate that this may be temporary. I will be mindful of anything I do with my Helix if/when the problem reoccurs. I shall have a look at the cleanliness of the rear connectors. I doubt that will be an issue, as I've been quite careful with it over the last 2 years, and it's always been in a relatively clean and dry environment.
  5. FWIW, it happens on the XLRs for me. The 1/4 inch L/Mono seems fine. That's got me thinking... IF this is a software problem, and it affects different outputs for different people. Maybe this is something to do with certain global settings. The first ones which spring to mind which I remember changing are: Global EQ affects XLR only, and Volume knob affects 1/4 inch only.
  6. Actually, I think I missed something in my original post: when I was testing at home with my audio interface, the right channel was connected at power up, and I unplugged it before checking the L/Mono output. Unusually, I powered it on just now with only the L/Mono connected, and I could only hear the left channel. So, it seems that it makes no difference what I'm connected to after all, the fault is the same. The only fix is to disconnect the right channel to activate mono. I opened a ticket.
  7. Yes. I'll do that later. No doubt they will suggest a reset etc., and I guess I might learn which settings I've changed from defaults as a result. By the way, I checked the gear specs. The mixer has 10kohm impedance, and the AI has 44kohm, which is not what I expected. I thought maybe the mixer impedance was too high to detect. Though I did read a very technical article about balanced gear once, and I think that there are different designs for balanced inputs, and that might be what's fooling the Helix.
  8. As a footnote to this: We had a rehearsal yesterday, and I tested TheElevators' workaround. It is absolutely spot on. Plugged into the Presonus StudioLive's balanced TRS input, using the Left/Mono XLR Out on my LT. Removed the mono block and, sure enough, only half the Ping Pong is audible. Mute the mixer, move the XLR to Right, and back to Left/Mono, unmute, and bingo, it's both channels. Power cycle the Helix, and the problem is back. I'm not going to use the workaround - it's too much hassle, and I'm a great believer in Murphy's Law. So, I'm going to use mono sum blocks for now, though that's less than ideal and not very satisfying. I'd like to know how Line 6 actually sums the channels at the output. Is it a straightforward 50/50 sum, or maybe there is a more subtle method used to combat any potential phase/delay issues.
  9. If I had to hazard a guess, it might be down to load detection. The Helix would either detect input impedances on one or both outputs, or see an imbalance between them. Maybe high input impedances can't always be detected properly.
  10. What would anyone suggest is the easiest way to turn a stereo preset into a mono one?
  11. Thanks. I tried your preset and it behaved as expected on my home setup. Unfortunately, I'm not back in the rehearsal room until next week, so I can't try it on the mixer. I have attached a preset which illustrates my problem. It has 3 snapshots for clean, distorted, and reverb-heavy sounds. I can't remember why the delay comes after the reverbs. Note that the initial Gain block is there for my Strat bridge pickup, and can be bypassed for a higher output. Also note the Stereo Width block at the end, which I recently added to overcome the left-only problem: it's there to show my attempted fix, and should be bypassed/deleted for testing. When plugged in to the rehearsal mixer, I only heard every other echo, and when I use snapshot 3 ('Bridge') with the new Stereo Width block, it's now not loud enough. My setlist has 12 presets, with 2 to 4 snapshots each. That's a lot of snapshots which are now potentially too loud or too quiet. Fortunately, I also use the mono Transistor Tape delay on more presets, but the stereo Dynamic Hall is on nearly all presets. I understand that there's a way to edit the preset (text) file to make stereo effects work in mono, but I don't know if this is a block's internal 'switch', or a way to swap to an equivalent mono effect, and only applies to effects with both mono and stereo versions. You have more than 2 Helixes?! Thanks. I shall try this next session. You're not selling this suggestion very well ;-) Shaken.hlx
  12. Some of my presets have not been behaving as expected at rehearsal. Then it occurred to me, that some of the presets, which I made at recording stage, are using stereo delay and/or reverb, and maybe I'm only hearing half of the story. So, back home, I added a Stereo Width block to the end of all the presets in my setlist, set to 'Center'. This made everything mono, so it shouldn't matter that I'm only plugging the left channel into the mixer. (Let's call this a 'mono block' for brevity.) But then I did a sanity check: I removed the mono block from a preset which had Ping Pong Delay, and unplugged the right output cable from my audio interface. The output was a mono sum of left and right. Auto mono output DOES work. Did I just waste my time? Today it was rehearsal. I tried the same patch again (no mono block), using the L/Mono output, and I only got half the delay output. So, I had to add the mono block to all my presets after all. At last, the question: what the hell is going on here? Why is the Helix only switching to mono on some connections and not others? I'm using an XLR Out to TRS In in both cases. Going into a Focusrite audio interface, mono works, and going into a Presonus mixer balanced line input, I only get the left channel. Annoyingly, some of the snapshots in my presets are now either too loud (more echo), or too quiet (reverb phase cancellation?) using the Stereo Width block to convert to mono. I could start to change some of the blocks to mono equivalents, but some don't have them. Is there a better way to go mono? Any wisdom on this subject would be much appreciated.
  13. I spent a couple of hours, listening to my riff, played on the neck pickup and bridge pickup, with the Looper as the first block. I tried the 3Sigma "Paul" IRs, which didn't really make much difference. I also tried a couple of EQ suggestions, with limited success. Then I spent ages trying to massage the EQ curve, with EQ blocks and amp controls. I realise that my request is a tall order, and that you will never get that close. They are different designs, with different tonewoods, pickups and scales. Really, it's a case of "what is close enough?" I sort of got near, but I'm questioning the sanity of trying to reproduce a riff and tone which was randomly recorded, when I really have better things to do!! But, I'll try the Tilt EQ next. I've not heard of that, and I'm intrigued.
  14. Thanks. I have tried the EQ route in a DAW, to see if I can get closer, and I think I'm getting nearer, but not near enough. I'll try these EQ suggestions and see if they work better, and I'll report back.
