I think it would be useful, speed up and improve the workflow. Especially, when switching override on/off.
I m thinking about A + Bank button for example.
Or in case of setting a range:
Keep the first A press, then press the last A of the range, after release the range LED turns on
The video below is a quick simulation example of when I need to turn the whole bank override A buttons.
This is a 1 bar breakbeat multisliced to 8 pads running on 4 bars
If I want to do level variations I go to multilevel. As it’s already recorded I have to press A one by one for all the slices.
In the end I press Shift+A if I want to change a slice for all the 4 bars.
Otherwise I press REC then press all the A buttons again and keep a pad pressed if I only want the change for a certain step in a certain bar.
If I want to switch the override state on/off it’s time consuming.
