How do you check which version firmware?and whats the procedure to update firmware on plaits
-- Broken-Form

The way I did it, was by trying if the color-blind mode works. You can find the details here: https://mutable-instruments.net/modules/plaits/firmware/ But basically, you turn on the module while pressing the right button. Instead of red/green LEDs, you'll get two levels of brightness. If that works, then you have v1.1, which is the latest.
