Really appreciate you sharing your experience. The consistency in shift/mod functions across the board is a big one, not self evident that it would be that way. After your first response I read the Oxi’s manual, it felt cramped just reading that but that’s not necessarily an indicator of the actual user experience with the device.
I def will try one down the line, I’m imagining it for eg a mobile setup. At it’s price point it’s not a huge “risk” to take anyway 
Now I’m super excited about the Hapax arriving hopefully in June…only issue is that — with the polyphonic limitations I had accepted in my sequencing setup before removed — I now also want an Iridium 
EDIT: @CarlosUnch do you know if the OxiOne is class compliant? I’m imagining that with an iPad could be a killer travel combo….oh boy, what have you done?!
