Mh, just played with it for a few minutes (I'll dive into it next weekend), but so far I've seen a few issues that will be hard to ignore:

* you can only use USB to control/update the device from a desktop app: too bad the app won't work on wine for me
* to have it seen as an audio device on desktop, I need to use USB-C (OTG) but that seems to have a noticeable latency (maybe because the device does 44100 and my Pipewire/JACK is 48000?)
* presets seem meh, but I really rushed through them

@lminiero I used to have a Ampero Hotone. The latency was also bad. But it was possible to monitor via the Ampero, so I used to send the Ardour mix to the Ampero, to play along and record new guitar tracks, with the headphones connected to the Ampero
