@MLaf - I have exactly the same problem, and it seems that there are other Midronomes with broken "Play" switches out there as well.
@Simon - To follow up on our email exchanges: could you give us any kind of timeline and indication about how you are planning to fix this, please?
Hello, trying to update firmware, but my Midronome does *not* enter into bootloader mode when I press the three buttons and unplug/replug the usb connection. Thanks for your help!
