Now, with the Airstep, the TONEX makes those 20 presets from the Preset Browsing Mode more easily accessible. That's nice but in order to do this, it runs in Stomp mode. That means that those two precious presets / amp tones you've selected for the Preset A and Preset B slots, after examining hundreds of captures, are now not accessible anymore. Solution: add them to the 20 presets.
I was kinda aware of the switching options - and for my personal use cases, I don't see that much of a limitation here, as the main purpose of the Airstep would be to deal with all the switching. Sure, ideally you'd be able to utilize the Tonex' switch additionally, but that's a pretty minor drawback for myself.
Fwiw, for me, the main drawback with the Airstep would be that I can only call up 4 patches per bank. There's some more or less regular gigs I'm playing where the feature set of the Tonex One would be pretty much perfect (ok, I might have to add a little RC booster kinda pedal in front to somewhat juice things up here and there). but I really need 5 patches for those particular gigs, 4 for electrics, one for an acoustic. Anything less would make things a lot less easy.
Along similar lines: There seems to be nothing to indicate the bank number, that's pretty bad. Guess you could partially work around that by coloring the patches per bank on the pedal, but that's a pretty bad workaround. A single digit display on the Airstep would be immensely helpful.
I also don't like dual switch presses at all - if they offered a mode without that but 5 patches instead, this would be vastly more attractive for me.
And then, buying a floor controller tied to one single unit is a bit of a questionable thing, too.
Maybe I should have a look at the Pirate MIDI offerings. With those, the Tonex actually becomes fully MIDI capable (so you could use any device to control it), I just don't know what to think of their browser based editor. And obviously, it's more of a fuss to set things up whereas the Airstep is pretty much plug'n'play.
Fortunately, I'm not in any kind of a hurry - and perhaps someone comes up with an even better solution. Ideally, IK would update their firmware so the Tonex One could communicate straight via MIDI, too. All you needed in that case was a MIDI-to-USB capable foot controller, of which there are quite some.
