sorry, that is a no for both.
you have to understand that the patch, once loaded onto the axoloti is actually a program that is compiled. so you would need a decompiler to get a patch again, not a trivial task...
or you look at the generated binary and you try to find the midi channel in there, good luck with that
hmm, best to find that patch again somehow. other "solution" i can think of is to get a second axoloti and patch up a midi channel offset. you can then feed the midi out of your offset axoloti into your patch... (or buy some other gear where you can change the incoming midi channel to something else)
