Hello there. I have been trying a similar thing and have of course the same problem here.
The scenario is:
I want to change Amp X and Cab X together to Amp Y and Cab Y with one switch. The reason why scene changing does not satisfy me is that I want jut to change from clean amp to drive amp leaving every other setup as it is. I want flexibility as if I use an analog amp and 4 cable method where effect chain is independent from the amp channel. Besides I also use scene power as expected in Ax8. So switching just amps when needed without changing the scene and also walking around scenes as I wish. I also recognized that only switching amp and cab without changing scene or preset works faster and produces less gap.
I assigned en external momentary switch (EXT3) to x/y change of Amp and cab block from SETUP - I/O. I works as it should.
The problem:
S1 is clean. S2 is drive.
When I press external switch ONCE while using S1, amp and cab switches from x to y.
When I press external switch ONCE AGAIN while using S1, amp and cab switches back from y to x.
However...
When I press first S2 and switch to y mode of amp and cab AND AFTERWARDS press on external switch ONCE while using S2, nothing happens. IF I press on ext switch SECOND time, then amp and cab switches back from y to x. And this goes the same when I switch to S1 and try to change amp/cab with external switch.
To generalize the issue,...
This type of problem also happens with any assignment of external switch as far as I tried. Bypass of blocks or any modification.
My conclusion is that the signal from external foot switch does not work freely as it should be. Namely it should have switched any state to its opposite whenever it would be pressed ONCE. But that does not work this way unfortunately. Even a momentary switch sends a definite signal to AX8 such as ...
First press switches from x to y OR from by-passed to engaged etc.
Second press switched from y to x OR engaged to by-passed.
And if by any means we change these states with some scene or preset switching AX8 does NOT forget the last state of our external switch. So it is to much clever where it shouldn't be
)))
P.S Scene revert feature or PC reset on modifier page do not also help with this issue.
Conclusion and wishes:
Is there any workaround for this specific problem? Is there any method of using external switch and scene/preset change together while they respect each other's decisions?
OR is there any possible way to change Amp AND Cab together without changing scenes or presets?
(Control Switches can be used in many ways to accomplish by-pass like things of multiple blocks. However, for x/y switching Control Switches cannot be used)
Thank you for your ideas and suggestions
Best regards
