Can't get Stadium XL to change my Suhr PT15 amp's channels properly

[boynigel]

Using snapshots, this worked perfectly with my LT.  To engage my amp's clean channel, via Command Center, i'd "Select: None", for the crunch channel, i'd "Select: 1 (Tip)", and for the lead channel, "Select: 1 and 2" in Command Center.

 

Wayyy more complicated w/the Stadium XL.  through much trial and error, given that i'm hooked up to the Suhr via the Control C/D jack, i found that when I:

Select: C (Tip), State: Closed gives me my clean channel

Select: C (Tip), State: Open gives me my crunch channel

 

great, but now to get it to switch to the lead channel of the Suhr... which is where it gets weird.

 

i discovered that if i set it as:

"Select: C and D, State: Open"  it'll give me my lead channel.   great, but now when i switch back to the snapshots that should be giving me my crunch channel, they're both stuck on the lead channel...even though  their correct settings listed above haven't changed, yet somehow the clean channel assignment remains intact.

 

weirder still, when i leave the preset and come back in hopes of returning to my unsaved state, the issue of being stuck on the lead channel held on somehow.  make it make sense before hulk smash Stadium!

 

here's a youtube link that shows exactly what's happening:

update.  i've gotten closer, but still not there.  these settings have helped:

 

Here are my new settings in Command Center:

Suhr channel 1 (clean) = C+D Close
Suhr channel 2 (crunch) = C (Tip) Open
Suhr channel 3 (lead) = C+D Open

This works fine, until i try switching from channel 3 (lead) to 2 (crunch). Now when i try going from channel 3 lead, to channel 2 crunch, it stays on channel 3 even though i'm on a snapshot that's set up to give me channel 2.  but...if i go from channel 3 (lead) to channel one (clean) first, then i can get to channel 2 on the amp.

So in short, if i'm on channel 3 and want to get back to 2, the only way is to go to 1 first, otherwise it gets stuck on channel 3.

 

 

What makes even LESS sense, is that if i go to another preset and assign everything the same via command center as outlined above, i can't get channel 2 on my amp to actuate, period.  Ugh.

Try this:

CH2 (C (Tip) - Open / D (Ring) - Closed)

You'll have to set up both as single commands.

Hope this helps

i'll try it, but could you clarify "single commands"?  maybe that's where i'm getting into trouble.

You have to set up separate Tip and Ring Commands in Command Center on the same preset/snapshot.

 

Go into Command Center.

On two separate Lightning Bolts choose Ext Amp

Set up one as: Tip - Open.

Set up the other as: Ring - Closed

Hit Save.

 

See if that's the combination for CH2 using the footswitches

okay i'll give that a try.  in the meantime i added a video to my original post that may better explain/show exactly what's happening

Hey, that worked!  thanks so much!  weird that i didn't have to do that w/my LT.  there's just one small issue remaining, maybe you have a fix this as well?  when i bring up a new preset, the amp is hanging on to the channel that it was on in the last preset.  this means that whenever i change presets, i have to hit my Snapshot 1 button to get the correct amp channel...unless by coincidence the desired channel happens to be the one that was on in the last preset used.

[XONE]

Glad that worked.

 

I don't use snapshots, so I don't know why that's not changing for you.

I only have my Presets programmed to change my amp channels 

[boynigel]

probably a global setting somewhere.  i'll figure it out, thanks again.

[XONE]

I figured it out.

In the EXT Amp Command Box, "right-click" on the word "Select" on the top left of the Box.

A toggle for Snapshot Control comes up.

Switch that "ON", and you should able to set up the commands per snapshot.

i already had snapshot set to On for each one.  in addition i also set State and Wait Time to Snapshot On.  it's buggy.  for example if i switch from a preset that's working fine, to one preset in particular, when it loads the preset, it changes my amp to a channel that isn't even assigned on any of my snapshots w/in that preset! 

 

Then i'll go to another preset and the original problem prevails, ie- when the preset loads, the amp will be on the wrong channel but as soon as i hit the snapshot foot switch, it goes to the intended/assigned channel.

 

and yet i can switch between other presets with zero issues.  i'm wondering if this a "bug" that i should report to Line 6?  unless i SHOULDN'T have set State and Wait Time to Snapshot On...except there are presets that work just fine this way.

I am sorry that you can't get it to work seamlessly. It's weird that it doesn't return you to the first amp channel (Snapshot 1) when the Preset loads

Maybe reach out to Line 6. I'm sure it's something simple that we just missed. It always is.

Let me know if you get it solved.  I'd love to switch to Snapshots

it took me nearly 10 years to adopt snapshots, mainly out of laziness/stuck in my ways, but when i finally did there was no going back.  makes life SO much easier!

Hey, I just did the 1.4 Update and it swapped the Ext Amp Commands, and I had to re-do them.

 

Here's from their 1.4 Update Notes:

• EXT Amp command states were inadvertently swapped (open was closed and closed was open). As such, post-1.4 EXT Amp commands will appear to operate correctly, but inverted from how they may have been programmed in pre-1.4 builds

[boynigel]

yep, me too.  now NONE of them work as i had them LOL

thanks for letting me know it wasn't unique to me.

Also check your Global Midi Settings,

there are 3 new midi commands sent out.

I had to go in my Global Midi Settings and 

turned OFF Matrix 1/4" Midi, Matrix XLR Midi, and Matrix Phones Midi,

then everything worked again with a restart.

 

Then I had to basically set my EXT Amp Settings to the opposite of what I had them to get the EXT Amp switching to work again.

Now it's all working again. Hope this helps.

I pretty much use my Stadium stand-alone, so i'll be addressing this later rather than sooner.  will definitely reference back to this when i get the itch to use it w/my amp.  thanks

My pleasure. I didn't want you to get stuck with the issue, especially since we had just solved it.
