I want to play sounds from my jv-2080 on my jv-90, especially with the following expansion boards: (sr-jv80-o2 orchestral, sr-jv80-05 world, sr-jv80-11 techno, sr-jv80-13 vocal)

So I wish to know what is the best way to make it possible, which midi channel to programm, if it is possible to make performances on a jv-2080 such on a jv-90, and I want to know if it is possible to change the patches of a performance on my jv-2080 from my jv-90. In fact, I want to know if it is possible to make performances exactelly as the same way as on a jv-90 but on a jv-2080 and change sound patches from my master keyboard jv-90.

Thank you for all info you can give me, I am a newbie on the midi domain.
