i tested this a bit again and i see a visual issue in the Amp and Delay block. when you change presets, many (not all) of the Values of the knobs in the Amp and Delay block display the numbers/knob position from the previous preset.
this does not affect the sound.
from there, if you go to the Edit view of the Amp or Delay block on hardware, Edit updates the values visually to the correct ones. but the sound never changes.
i also tried going to a new preset, seeing the "old" values, then pressing Save. the "old" wrong values do NOT save or overwrite what is actually there (visible on hardware). instead, the preset is saved (with no changes) and the correct values are displayed - nothing changed.
i also went to a new preset, seeing the "old" values, then changed just one parameter to see if that somehow "locked in" the other visual errors. it did not. changing that one value and saving only changed that one value, and the other knobs snapped to the correct values (visible on hardware) as before.
as far as i can tell, there is just a visual issue where Edit does not update the values of the Amp and Delay blocks in a preset you go to, instead displaying the values of the last preset you were on. again, only visual. if you go to the Edit screen of the Amp or Delay block on hardware, the correct values immediately load. the sound does not change in any of my tests, it's purely visual.
i'll keep testing to see if i can recreate any other issues mentioned in this thread, but during testing and after release, i did not see anything like what's been mentioned.
