Multiple Midi controller

[lukakiro]

Hi,

two questions:
-is there any way I can use 2 or more midi controller as input?
-I've create a frame with 2 pages and in the second page I placed a frame solo with 2 pages. To change page on each frame I setted a button on the midi controller. The first frame works well, but I'm unable to change page in the solo frame with the midi controller. How can I solve it?
Thanks
