Is anyone else having this issue?
I've tried downgrading firmware and everything works fine.
Upgraded to 2.20 multiple times, different USB cables, different ports, WindowsPC and Macbook, no setlists or IRs added, just firmware presets. No luck.
Scrolling through the presets on the Helix with no USB connected and after 3 - 8 different presets the output disappears and I think the Helix input is locked up because the tuner is locked on Ab.
The tones sound great with the upgrade but I don't think I should have to power off/on to change between them. :unsure:
