Hi @brusch !!
Thanks for the reference @jesseverhage !
Yes, I´v been using FCB1010 for a long time (with my Avid 11 Rack), and now, it´s really usefull to work with the ModDuo, while I´m waiting for the Extended Footswitch and Expression Pedal from ModDevices.. .
My FCB1010 has an EurekaProm 3.2 chip, that is a really helpfull and great enhancement to control all the things (because has a lot and diffrent configs)..and, I can tell you, the MIDI learn of Mod it´s an awsome feature, and works really fine with it!
The only "issue" (I don´t know if it´s an issue, or not..) that I had, was, at the first time that I´d tried to connect, the MOD did not recognize any MIDI control when I´m using only MIDI cable direct (MIDI OUT of FCB x MIDI IN of MOD).
I needed to use a Ediroll (or any MIDI x USB), to connect MIDI x USB at the first connection to the MOD .
After that, I can use it only the MIDI cable, that works great.
The 2 expression pedals works fine and control any parameter that could be mapped (Wahs, Gain, etc..).
And you can map any other CC# to a various parameters of the plug ins.
The Program Change works great too.
All depends of what config you are using in the FCB.
If you need some help or some tips, just ask.
