It's easy to come blind to your own work, so having a fresh perspective (someone who has never used it) can be useful.
I feel Fractal's approach to UI design has often been based on:
- This is how it was easiest to program.
- That's why moving blocks is a nightmare on the onboard UI. It makes sense from a programming point of view: "Execute function to move block/row/column left/right/up/down" as row/col matrix manipulation. But it is completely unintuitive for the end user.
- Cram the new features somewhere in there, but don't spend time making them truly user friendly.
- For example on the Triple Crown model, you just need to know to turn on a TS input boost to match the amp's "Tight switch". Why not just have a "Tight" toggle switch in the Authentic view that does that for you behind the scenes?
- Don't spend any effort iterating on the onboard UI until next gen.
By comparison we have seen some improvements and redesigns on Axe-Edit that are most welcome. I guess this is because those are much easier to do compared to the onboard UI code.
Overall
all modelers are somewhat unfriendly to new (most likely hobbyist) users because they expect you to know about:
- Effects order and routing. The idea of "fx after the amp/cab" is foreign because you don't do that in anything but a studio environment.
- Amps vs cabs. For many people amp = combo amp = speaker.
- Micing an amp. Many people who have been playing real amps don't have any idea how to do it, at most they've used a smartphone to record themselves. So when you throw them things like movable mics, different mic models, low/high cuts etc they don't know what to do.
- Output systems. "Why my cheap ass headphones don't sound as good as my relatively decent combo speaker at twice the volume in the room?"
I don't like the Fender TMP for example because in some ways it feels too dumbed down for someone like me. But can see why it'd be liked by people who are used to using a combo with some pedals. Helix UI and its derivatives (QC, Hotone) strike a good balance where they work pretty well for both less experienced and power users, but obviously they have their own issues too.
