I just bought a used hx stomp XL from a music shop a few days ago and I am encountering a couple of issues.
It is sometimes freezing on the loading screen and when scrolling through presets using the knob near the screen. It also has happened on the global settings at one point and when changing footswitches on snapshot mode.
I have tried updating to the latest firmware and factory resetting but it is still happening intermittently.
Also, the touch capacitance works for everything (swapping and copying snapshots ect...) but does not redirect me to the effect parameters page when I try to using it in stomp mode. Not as much of an issue but something I noticed too.
