Create a button to reroute MIDI Input to a different channel?

Question

Let's say I have a keyboard transmitting on MIDI channel 2, connected to a 16 channel multitimbral sound module, and I'd like to create 16 on screen buttons which I could use to instantly choose which of those 16 sounds I was playing (i.e. which of the 16 channels I was transmitting on), toggling so that, for example, if I was playing the sound that was associated with MIDI Channel 4, and hit the 5 button, it would stop transmitting on channel 4, and start transmitting on channel 5. Is this something that can be done?

To make it trickier... Ideally, I don't want held notes to cut off when making the change from the Channel 4 sound to the Channel 5 sound. So rather than do the easy thing and send All Notes Off when about to change to the new channel 5 sound, I'd want it to switch to 5 but still send any subsequent Note Off events from previously held notes to channel 4. I suspect that the logic for this may be beyond what this app can do?

You need Midi Fire, the new app by Audeonic (replacement for MidiBridge). Even if you could do this in MD, it would be quite kludgey. A Midi Translator would do what you need.
