Change programs to combination with midi

[Angelomaga]

Dear all
I write from Italy
My question is to know if it exist the way to change the programs with the combination by a midi message: which it should be ???
I play 2 Keyboard: a Clavia Nord stage that is the master and a Korg Trinity that is the slave. It should be wonderful to play a sing with the combination and un'other sing with the programs to use the full performance of Trinity. Of course the change must be with a midi message sent from NordStage to Trinity!
Thank you in advance
