MIDI lack is a deal breaker for me. I still think it´s probable that a USB host can handle it (a PC, a smartphone, or a MIDI-USB host adapter), as it does on almost any pedal I know of. Zoom units respond to that MIDI, also Boss GT-1, all Hotones, Valetons, Mooers... all work with a USB-HOST capable device. I guess (just as an assumption) that any pedal with software editor can be handled by a USB-HOST, at least for preset changes.
Even so, it´s annoying to need a proper host adapter, with its cables and PSU.
Also, the input gain problen is still there. For those of us who pay attention to it, and don´t want to deal with guesswork, it´s a bad thing.
All in all, I find it interesting because of high quality profiling and size... but a personal no-go because of no midi and no standardized input gain system.
