I have a Scarlett Solo interface. It won't work with ToneX. I can't hear the amps, just my clean guitar tone then the monitors. It's impossible to edit presets this way. Works fine on Amplitube.
The audio settings read as follows on ToneX app:
Technology: ASIO
Input Device: Input 1
Output Device: Focusrite USB ASIO
Left Monitor: Output 1
Right Monitor: Output 2
I'm at a loss.
