To sum up what I heard today at the Messe:
Xavier, the guy who makes the UnO chip, is working on an eprom specifically for the KPA.
This eprom will enable the FCB
- for a special learn mode
- 2 way communication ( i.e. switching an FX on the KPA will reflected on the FCB)
- tuner LEDs will be visible on FCB display.
Boom. That's what I wanted to hear. As the FCB1010 is midi only, my bet is the 2-way communication will actually work with many foot controllers (including the UNO FCB).
