OK, I've been searching and found a few unresolved discussions not quite the same as my issue.
I have a 500 and a 500X doing the same thing with copied patches, global settings have been matched.
I want a non cab sim amp from the pod Left out into my Marshal tube amp FX return, I've been using like this for years, sounds great.
I also want another signal to an in ear mixer with a cab sim so it doesn't sound like poop.
Sounds easy, make a dual amp patch with mixer as the last in the signal, pan one for the amp left, other for mixer right.
It works! Sounds awesome. I copy the patch with the conversion tool to load on the X and both guitars should have a good signal to mixer and amps.
But after playing for a min, switching patches as usual, i can hear the tone change, particularly to the amp. Now the amp is getting cab sim signal and sounding boomy.
I check the signals several times and confirm the signal is mixing like it's not panned! I verified by panning both hard right, but still have sound on both outputs. Same visa versa.
I can play around with it for a minute and get it to pan again, but it always ends up bleeding across after a minute!
What is going on?!
I have two patches with varying pedals doing the same thing. If I plug usb in and run 500 edit, it seems to fix until i start changing patches.
Try the patch for yourself!
Any help?
Cables are connected as follows,
Guitar in 1/4"
L/Mono 1/4" to amp fx return
XLR Right out to mixer
(I've also verified the issue with just headphones, so I don't think it's a cabling issue or anything external)
Global settings,
Studio direct
Input 1 guitar, 2 Same
