I recently came across a comparison between the LINE6 HELIX STADIUM XL and the AXE FX3.
Regardless of the fact that the comparison should be made with the FM9 instead, a great part of it were to explain the advantages of having a touch-screen.
I have the following considerations:
Having a touch screen can give a sense of modernity and
appeal to many users, especially entry-level ones. For example, it's nice to see
images of the amplifiers to be click on instead of a list of their names to selected from...

... ... If this is way to make the things easier: thumbs down.
I'm absolutely pro-touch screen in nearly every context: I use them in PCs, my watch, my Korg keyboards and they are very useful and faster than any other UI.
I know I might be going against the grain here, but... in my opinion, for serious/professional live use, a
touch screen on a floor unit is a significant
weakness — regardless of whether it’s
capacitive or
resistive.:
- It's mechanically and electrically fragile, more environmentally sensitive
- Floor units are often protected by plexiglass covers, mainly in the screen, which makes the touch screen unusable
I'd much rather see
BT/WiFi added, allowing use of "FMxEdit" from a tablet/smartphone:
- You can adjust sounds while standing upright, without having to constantly bend down (I consider it a part of UI approach)
- Your touch UI stays away from possible knocks and spills of beer...
- It can be the same tablet/smartphone used to adjust your IEM settings
- You can choose the best display size for your use
- If you break your "touch screen" it's easy to replace in just a few minutes
On the contrary, I would like to have a touch screen in the AXE

but only as an
additional interface and not an exclusive one, keeping the possibility to do everything with buttons and knobs.
