Hi Gijs, We're using Ubuntu 16.04 on our BBB based midi controller - and that saves about 30 seconds on the boot time and the system is generally much better behaving than under 14.04. The image I use for flashing are from : http://elinux.org/BeagleBoardUbuntu - basically using an SDCard with the flasher to flash.
I use an a bit of code in my apps to change the polarity - but basically it comes down to entering a 0 or 1 into the gpioXX/active_low I've recently modified the simpleGPIO lib from Derek Molloy to include this code over the past weeks for a small project.
