Problem Copying a preset on a Helix LT

[franstone]

First off, I'm using a Helix LT ver 3.50 and HX Edit ver 3.51 under MacOS High Sierra 10.13.6. I created a preset with four Snapshots (SS) and four effects. The preset works exactly as I created it - no issues. I Copied and Pasted the preset into an empty preset to make some minor changes to my Volume/Gain block. While using the copied preset, SS 1 sounds and works correctly. The volume levels on Snapshots 2, 3, and 4 are very low (less than 50% of SS 1) and are somewhat distorted (they should be clean). The strange thing is when I switch to back SS 1, the volume drops and it is also distorted. I went through the copied preset block by block, and the settings looks the same. I tried Exporting and Importing the original preset with the same results. Tried shutting down HX and rebooting my computer with the same results. I can't figure this out. I've had my HX for about four years now and have never encountered this. Any help is appreciated.

Is this only happening with the one preset or is it a general problem with all presets? If only one, can you attach the preset here so that others can test it?

Do you have a volume pedal in the presets?

I don't have a problem copying different presets. I've attached the original and the copy "cp".

 

I don't have a volume pedal in the preset. I do have a Volume/Gain block (for solo boost) assigned to a foot switch in every Snapshot.

I just noticed that the size of the original 77.07kB and the copy 76.95kB are slightly different.

I ran an FC file compare command ('diff' for Windows) and although it is possible it didn't compare the files properly, it does show many differences in the 'FC' output between the two. Most of the differences seem to be on the same keyword/value pairs in different sections of the Json file. One thing that struck me is the following, which I did verify as a difference both in the FC output and the files themselves, don't know how significant it is but it looks like it could be although "false" and "0" might be equivalent. Still interesting that they use different text:

***** HumanSoldClnOD.hlx
 1563:              "@position" : 99,
 1564:              "@behavior" : 0
 1565:            },
***** HUMANSOLDCLNODCP.HLX
 1563:              "@position" : 99,
 1564:              "@behavior" : false
 1565:            },
*****

 

Or this, the keyword/pair that occurs throughout the file.

***** HumanSoldClnOD.hlx
  768:                  "@fs_enabled" : false,
  769:                  "@value" : 0.3000030517578125
  770:                }
***** HUMANSOLDCLNODCP.HLX
  768:                  "@fs_enabled" : false,
  769:                  "@value" : 0
  770:                }
*****

 

Interesting that the copied preset is a different size with different content. Are you sure you didn't modify one of the presets inadvertently before exporting them?  Have you restarted your LT since you copied and pasted the preset. Copied presets often (always?) do a rebuild after the next restart. Wonder if this would render them both identical and the same size? I would test with a fresh copy and paste first and then immediate restart. Test the size of the two files after this test. Don't have my Helix out of its backpack at the moment or I would do some copy/paste tests myself.

 

Was also ruminating on whether there could be a global setting that might affect the contents of the saved file such as for example, setting 'EXP 2 Pedal Position' = 'Per Preset' and then moving the expression pedal before the export.

 

Lastly, did you do a backup and restore after your last firmware/editor upgrade? All kinds of weirdness can occur down the line without this step.
