With the Kemper player I assigned bank up and down to footswitch 1 & 3. The two footswitch-led are constantly yellow and blue.
I think could be really useful to have them representing the colour of the bank that will be activated by pressing the footswitch. Or even better having the internal led representing the next bank, and the other for the "next next".
Bonus: I'll finally lern the sequence of color 😂
