Changing patches on slave with Midibuddy

[rockitboy]

Hi Everyone,


Midi newbie here ! I use a Roland piano (master) and midi it with a Korg X3 (slave), Sometimes I play the Korg on it's own keyboard and sometimes I midi them
and play them both from the Roland. I recently purchased a Rolls MP 128 Midibuddy to make patch changes on the Korg using my foot instead of having to do it on Korg keypad. What I am trying to figure out is how to use the Midibuddy to change patches on the Korg ONLY. I need to plug the Roland into the Korg, but since it has only 1 "midi in" , how do I also plug the Midibuddy into it to change patches ?
Thanx for your time.

Don

Something like this - a midi merger.

Roland into 1 of the "ins", Rolls into the other "in", "out" to Korg.
