Hello, my name is Rusty. I think what's going on here is your midi channels. I'm seeing mention of channels 1-16, but let's take that a bit further.
When you're controlling midi, remember that each midi channel is a path to send another set of midi signals. Basically give each element its own channel, and the receivers will change as necessary. For your Midi Solutions, be sure to set that up on an unused midi channel. It's not difficult, just think each part one at a time, and assign the midi channels accordingly. Reading your question, it seems like you may have set up the basic midi, so go over your setup again, and double check that every path has a unique send and receive channel. As long as they match (send and receive), it will open 2 way communication between the devices that are listening in on that channel.
Getting into the SysEx is not any more complicated than setting up basic midi channels, but it will take some understanding. Click here. There are different examples of how to set up those numbers, see if you can get your system to work like one of these models. We'll adjust if necessary.
