Arbitrary midi message from midi controller

[jaberbob]

Hello!

I am using mainstage to control program changes and routing for my keyboard rig. I have a midi pedal I want to be able to assign to arbitrary midi signals for each patch on mainstage. Specifically, for one patch, I want to send a single note on/off messages to a particular software instrument. I could map the midi pedal directly to that note, but then that pedal would be reserved for that one patch, which seems ridiculous. For another patch, I might want to use that pedal to send control change messages or perhaps a different note on/off message. I can't seem to figure out any way to do anything like what I want to do. Any tips? If there is any hardware that can be programmed flexibly like this (I send a midi message to it with each patch to specify its routing) that would work, but I'm not aware of anything that does this. 

 

Thanks!
