Hi Roland,
Hope you're enjoying the module!
I've added a VALUE jack where a -5v to 5v signal corresponds to 0 to 255, so sending in an LFO gives you interesting patterns (but does sort of go against the point of the Gray Code to begin with, but it sounds good!)
I'm not sure about the preset knob for this particular case, but based on this module and looking at a range of ideas based on the concept of converting a signal into an 8-bit number, then splitting out those individual bits. I'm having some fun using the 8-bit values as sequences, and sending in related numbers each bar to get anew sequence,m such as the below:

Coming soon... hopefully!
