I made precise adjustments for the preset #79 on Marshall Code. I tried many times to share it; my amp is well plugged to my computer, and each time I try to share my own preset I get this message: "You cannot share this preset, as the settings match an existing Factory Preset." I don't understand because my own adjustments don't match the original Factory Preset...
Has anyone ever had this problem?
Once again, I come to answer my own question ;-P I think I found out what I did wrong.
When you save your own presets on your Gateway App, once you've clicked on "Save" there's first a rectangle called "Amp", and underneath another rectangle called "Library"; you have to tick both, make sure there's a little X cross before "Amp" and "Library". This modification made it work well.
