question about controlling 2 midi units with one midi controller

[weatherbill007]

I was wondering if there were any midi foot switches made out there that allow you to control two seperate midi pieces with one controller and the controller controling them seperately, kinda like a top bank of switches would control one unit and the bottom bank controlling another.
I am looking to get a midi set up for for a vocal processor, so I can change vocal fx witha midi pedal on stage..... and also control thru midi foot switches, a sampler with stored sound clips..... is there a midi foot switch unit that can control both these units seperately, instead of me having to buy two different midi foot switches......my thinking is that the midi foot switch unit would need to have two midi out jacks to go to both the sampler and the vocal fx unit.........

If one of your processors has a MIDI Thru port, it will echo what's coming in the MIDI In. You should be able to set the MIDI REcieve channel of the processors. So you can send messages on, say, channel 1, and only one device will pay attention to them, and other messages on, say Channel 2, and the other device will listen to those.
