I did try using a MPR121 for 12 capacitive touches and a second MPR121 for 6 more 'knobs' and 6 status showing LEDS.
It works like a charm! Thanks for the objects! Great job. The only thing I have difficulties figuring out is how to drive the LEDs. I have been looking and reading around on the forum, but did not find whether or not some objects have been written to drive them. Anybody ideas?
For now my project is quite feature-full; Since I have not introduced myself on the forum before, I'll try to do a short presentation of my box in the near future. Thanks for all the good work that made figuring this out so much easier!
