Did you use it some more by now?
I'm traveling a lot for work, and the Airstep is quite heavy, so I didn't take it with me.
And at home I don't use TONEX, I have other options.
The TONEX One has two operating modes:
1)
Dual Mode: switch between Preset A and Preset B, using the main switch. You already discovered this mode, with the Dumble being preset B.
2)
Stomp mode: the pedal acts as a stomp box (overdrive) before a traditional amp or modeler.
When you press the main switch in Stompbox mode, the virtual stompbox is turned off, and you get a direct-through signal.
Which is handy when the pedal is before an amp, or when connecting the pedal to a computer and use the Tonex simulation from the software, not the pedal itself.
There's an additional 'mode':
Preset Browsing Mode. Through a difficult switch combination and knobs with too little range you can -in theory- switch between 20 presets. Too difficult to use to be useful without software.
To switch the TONEX the the two main modes without software, you have to hold ALT for like 6 seconds and use the Bass knob to switch modes.
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.
