Good job, standingwave!
Nice to see what others are up to. It should be of interest to both experienced and beginner synthesists owning or cpnsidering the MxB!
I also like to make paraphonic patches, sometimes with even lower levels to avoid saturation on certain note combinations. You can get some very smooth sounds with it. One thing about paraphonic that is little talked about: the voices/oscs sharing the filter section is akin to acoustic instruments that have a single resonant body, like e.g. piano and guitar, giving a different feeling than a filter on each voice. And of course on the MxB you can make a huge variety of those "resonant bodies".
