I recently bought an M-Play wing, and are now trying to update the firmware in order to get more responsive fader action. To do so, I've understood that I need to boot the M-Play in bootloader mode by pushing a button in the bottom of the small hole by the Martin logo on the side of the wing.
I have followed the instructions on the official website, but the problem is that there is no obvious button to push in. I'm trying different angles with the toothpick but just can't seem to find one. Anyone else having this problem? It looks like all pictures in the tutorial are on an M-Touch, but the text refers to M-Play as well.
