Thanks for your answer Edo.
I don't understand exactly what you say, but it is not dramatic. I must think about it !
I know that I/O setting (Axe FX II) and Input Status (Axe Edit) is something different, and at the moment it is enough for me.
(All things that I say or have tried is just to try to simulate the problem of Zolaive by myself in order to help him, and nothing else ; I have personally so far no problem with your presets)
But now, i must say that between I/O setting in Axe FX II and Input status in Axe Edit, both with the choice (left/right/sum L+R, .), there is a nice opportunity for confusion for people like me
Poll: How many owner of the Axe FX II really know the difference between I/O setting in Axe FX and Input status in Axe Edit ?
(just for fun
