[Dwarf] Control mode bug after saving snapshot

Contribute Bug Reports
#1

Description

After saving a snapshot and switching back to control mode (B+C), the HMI seems to still be in snapshot mode, leading to a faulty screen.

How to reproduce

  1. Switch to pedalboard mode (B+C)
  2. Switch to snapshot mode (A)
  3. create new snapshot or just overwrite the current entry by pressing SAVE twice
  4. Switch back to control mode (B+C). The screen should show the controls correctly.
  5. Try switching to another control page

Expected/suggested solution

The control mode should work normally. (When pressing B+C again the control mode works correctly.)

hah, you found the bug I was giving low priority to due to perhaps it being uncommon. :sweat_smile:

it is already on the sprint for things to fix, thanks for noticing though, it increases the seriousness of the bug if not anything else.

Ok, good to know, thanks :slight_smile: Maybe it’s uncommon, but it represents an actually common workflow when tweaking the sound of a specific snapshot on the device. I’d then switch between snapshot and control mode quite often.
