I solved it. I have a registration memory with 4 variations. It was a bit complicated because what is altered when pressing the registration buttons depends on the default values of the voices and styles, for reverb and chorus. Those effects cover both the voices and style plus the microphone. BUt it makes sense that the reverb type would be the same for the microphone as for the instruments: ROom, hall, medium hall, stage etc. So programming just the wet amount at a fair value covering both large hall and medium hall etc would make the microphone and instruments fit: Or one saves it along with the registration banks of one's various songs and styles, hence not needing to alter that once stored.
Else just registering the microphone (DSP 5) and and memorizing just the Mic values, makes this value available in all situations and you simply choose your setup of sounds etc (including an already saved memory) and then push the saved registration of the mic value, afterwards (in that particular registration memory saved at the front of all other memories), which will not alter other than the microphone's wet values (rev, chor, microphone DSP) plus the dsp 5 type of effect for the microphone exclusively.
