preset level lower sometimes based on the previous preset

[PaulTBaker]

I posted something earlier about this (sometimes when I select a preset, the volume is 3 to 4 db lower).  This is what I have learned.   I have multiple presets (duh :) ).  I have two that are using the Double Black amp. One has two cabs and one has one cab.  I switch to a different preset that uses a different amp (Lux Blk, Princeton, or Plexi).  The volume on all of these presets are fine.  I will then select one of the Double Blck presets and the volume is 3 to 4 db lower than it should be.  If I select the other Double Blck preset and then come back to the first Double Blk preset, the volume is normal (3 to 4 db louder, which is how I set it).

 

I have (hopefully) attached the two Double Black presets and one of the others that makes the Dbl Blk preset be lower.

You can test this by:

1. select the Lux Blk preset ... play something

2. select the Dbl Blk Opto preset ... play something (it will be lower that it should)

3. select the other dbl blk preset ... play something (it may or may not be lower)

4. select the Dbl Blk Opto preset again ... play something (it will be 3 to 4 db louder)!!!!!

 

I have tried this with the Stadium connect to the pc and not connected... I get the same results

 

Does anyone else have this issue?  Can someone please point me to the Helix Stadium Bug list post?

 

thanks

Hey guys, reaching out again.  Would love for someone if they have time to test these patches and see if you get the same results (the volume of the dbl blk preset is lower when switching from the Lux Blk preset, and doesn't go back to normal until you select the other dbl blk preset, sometimes you have to do it a few times).

 

Really want to know if anyone else has seen this.

 

Thanks.

1. Did you create these in the Stadium App Editor on Windows 11 or Mac OS?

2. What version is your Stadium Unit on?

 

The three files you posted appear to be corrupted. There are only a few lines of JSON code in each of them. This is evidenced by the fact that each one is only 1K in size.

 

try building out these three presets using only the Stadium Unit itself. Don't even use the Stadium App at all. It really is just as easy - though a different input device. Make sure that your Stadium is on v1.2.1 of the Firmware. You must use the Stadium App for this update, if you are still on v 1.2.0

 

Then retry your newly built presets and see if you still have the issue.

 

I had a corrupted preset when I used the Stadium App and sent it to Line 6 support. I am not sure if they have fixed the issue - but there are still issues with the Stadium App.

Thank you for the reply. 

Good questions:  On Mac, created in the app with back and forth editing between the app and the unit.... on version 1.2.1 app and unit.

 

I found out last night that the files exported from the app were corrupt.  Found out that dragging the file to finder from the app does not work.  Right clicking on the preset and selecting export does NOT work.  The only thing that does work is the Export Preset under the File menu.  

 

the files are attached here.

 

I did some more testing and have found that it seems to be just the Dbl Blck amp.  I took a preset that worked fine (meaning it is always the same volume whenever I click on it) and replaced the amp with the Dbl Blk amp and now I get the different volume issue again.

 

I will try creating a new Dbl Blk preset without the app and see what happens.  this is really crazy!  Thanks

ok, I created a new preset entirely on the Helix Stadium XL(unit) using the Dbl Blk amp.  Using the YouLean Loudness meter on my Mac (Catalina v 10.15.7), the reading of my new Dbl Blk preset was around 18 LUFS (short term) with steady strumming.  I click on other presets (not Dbl Blk and a combo of made on the unit or brought over, its all the same results) and the volume on those patches are around 18 which is how they were created.  I then click on the xDbl Blk Opto preset and it is 18.  I click back on the new dbl blk preset and the LUFS is still around 18.  I can select any of the other presets and get the correct results.

 

this may make it easier to read.  all presets were created to have an LUFS around 18:

 

4a = Dbl Blk test (created only on unit, has 2 snapshots)

1a = Dbl Blk 3snaps (created using app and unit, has 3 snapshots)

2a = Dbl Blk Opto (created using app and unit, has no snapshots)

 

1b = Lux Blk 3snaps (created using app and unit, has 3 snapshots)

1d = Plexi 3snaps (created using app and unit, has 3 snapshots)

 

restarted the unit, rebooted the mac, unit is NOT connected to mac by wifi, unit IS connected to map by USB so I can use the YouLean meter.

 

- select 4a, get LUFS 18

- select 1b, get LUFS 18

- select 1a, get LUFS 18

- select 4a, get LUFS 18 --- normal levels up here

- select 1a, get LUFS 12 to 14  -- elevated levels after I select any Dbl Blk preset after a previous Dbl Blk preset

- select 4a, get LUFS 12 to 14

- select 1b, get LUFS 14 to 15

- select 4a, get LUFS 18 --- gets back to normal since the previous selection was not a consecutive Dbl Blk

- select 1b, get LUFS 18

 

 

So, clear as mud?  :)

 

I do not believe the creation location of the preset matters (unit or app).  My tests indicate that after you select after you have select 2 Dbl Blk presets, the next preset will be louder. this will continue if you keep selecting a Dbl Blk preset.  This behavior will go back to normal, you select 2 consecutive NON-Dbl BLk presets (the first Non-Dbl BLk will be loud, but the next preset (dbl blk or not) will be back to normal levels.

 

please someone with time to burn try this.  you can use my presets or create two dbl blk presets and some other non dbl blk and test it.

 

Also, is there a place where I can post this to Line 6 as a bug?  I know they do not monitor this forum.

 

Thanks.

 

PS.   now it seems like the loudness could be more random... switching between presets will give my different results for the same preset.... sometimes you can just re-select the same preset and it will get louder...... you can hear it get louder and fuller or thin and soft.

Yes. Open a support ticket to report a bug.

1. Not sure what the 4a, 1b, 1a stuff is. I am assuming that is the preset numbers that you are referring to and how you have your Stadium configured (as It can be changed).

 

2. If you open the "dbl blk 3snps.hls", the "lux blk 3 snps.hls" and the xDbl Blk Opto.hls" in a text editor, they are the same, including the Amp model (ALL THREE files show "Agoura_AmpUSDoubleBlack" as the Amp model. So it looks like you have posted the same preset each time with different names. I am not sure what is going on there. They can't be different presets since you say that they have different snapshots and that information would be reflected in the files even if all of the blocks were the same. Also, the name is showing "Dbl Blk 3Snps" in all three files and the file sizes that you uploaded are all identical as well.

 

3. I did notice that you have a Wah pedal in the preset "dbl blk 3snps.hls" and that you have set the minimum and maximum values on this. If you are not using the Wah pedal at all in your comparison then it should not matter, but if you are, make sure that the volume pedal is also set to 100% when you turn the Wah pedal off.

 

4. I also noticed that you have a Deluxe Looper at the end of your chain and that it is turned on for snapshots 1, 3, and 4, but not for snapshot 2. This too should not change anything as the setting you have are for playback in the Deluxe Looper. But for testing, I would take anything out of the preset that could change your volume just to eliminate user error. I advise this also for the Wah pedal mentioned earlier.

 

Make sure that you are documenting everything, so that you do not get confused, and that you are very methodical in your analysis. Try to nail down exactly what is going on. Then reach out to the this community here (as you are doing), and then create a ticket with Line 6 when you have something concrete that they can chase down.

Thanks for the replies. 

 

1.  Yes the 4a, etc were the presets.  It made it easier to read. 

 

2.  I will check the files I uploaded.  As I posted, I have been having issues trying to export files (the problem is probably between the keyboard and the chair :)  ).   Lux Blk 3Snps .hsp I found out that if I try to select multiple presets from a setlist, and drag or export to a folder in Finder, then it exports a very small file for each preset.  My guess is that since the user setlists contain links to the actual preset in the USER set list, then it is the link that is getting exported.  I have uploaded the correct Lux Blk preset.

 

3.  I do have the min/max values set on the wah's, however that should not come into play because simply selecting the preset causes the change in volume.  I am not engaging any stomps... The same preset is at different levels depending on what combination of presets were selected before it.  In the case of the Dbl Blk 3snps preset, you can select once and it may be low volume, then re-select, and it is at a higher volume.

 

4.  you are correct about the looper.  the presets are saved to start on snapshot 1.  The deluxe looper is grayed out in 1a "Dbl Blk 3Snps" and 1b "Lux Blk 3Snps", so they are set the same.  

 

This is the scenario: 

1.   I select preset 1b, the LUFS is 18.  I do this to make 1a be 18 when I select it.

2.  I select 1a, the LUFS is 18

3.  I select 1a AGAIN, the LUFS jumps to 14 and ANY other preset that uses the Dbl Blk amp will stay boosted, until I select a preset with a different amp.

 

Thank again for letting me share my pain!  I am going to make a ticket for this.

I'm posting this so I will have a record of what I have done... and in case anyone out there really wants a headache :)

I created a ticket, so we will see what they say.

 

Ok, so I have some basic template that I made from scratch on the stadium unit.  i created 2 presets from this template.  One with a Dbl Blk amp and the other with a Lux Blk amp.  I get the same behavior.  The Dbl Blk amp preset is louder if you select it again after selecting it the first time.  It will get softer after you select the Lux Blk preset.

 

Ok, so I created two presets with just an amp and cab.  One had the Dbl Blk and one had the Lux Blk.  This time selecting the Dbl Blk preset twice did NOT increase the volume (which had happened in ALL other cases). So mmm?  However, when I selected the preset based on my template that had a Dbl Blk after I selected just the amp/cab preset, that preset was louder.  ALSO, when I went back to the amp/cab Dbl Blk preset, THAT PRESET WAS LOUDER... it is just the amp and cab!

 

This is very weird.
